ORDERING INFORMATION PET 800 - 12 - 074 x A Product Family Power Level Dash V1 Output Dash Width Airflow Input PET 800 W 12 V 74 mm N: Normal R: Reversed A: AC 2. OVERVIEW The PET800 -12-07 AC -DC power supply is a mainly DSP controlled, highly efficient front-end. It incorporates resonance-soft-switching technology and interleaved power trains to reduce component stresses, providing increased system reliability and very high efficiency. With a wide input operating voltage range, the PET800 -12-074 maximizes power availability in demanding server, network switch, and router applications. The front-end is fan cooled and ideally suited for server integration with a matching airflow path. The PFC stage is controlled using interleaved Critical mode to guarantee best efficiency and unity power factor over a wide operating range. The DC-DC stage uses soft switching resonant technology in conjunction with synchronous rectification. An active OR- ing device on the output ensures no reverse load current and renders the supply ideally suited for operation in redundant power systems. The always -on standby output, provides power to external power distribution and management controllers. It is protected with an active OR-ing device for maximum reliability. Status information is provided with front-panel LED. In addition, the power supply can be controlled and the fan speed set via the I2C bus. It allows full monitoring of the supply, including input and output voltage, current, power, and inside temperatures. Cooling is managed by a fan controlled by the DSP controller. The fan speed is adjusted automatically depending on the actual power demand and supply temperature and can be overridden through the I2C bus. Figure 1 - PET800-12-074 Block Diagram

Grounding The output ground of the pins of the power supply provides the output power return path. The ground output at the PCB card edge shall be connected to the safety ground (power supply enclosure). This grounding should be well designed to ensure passing the max allowed Common Mode Noise levels. The power supply shall be provided with a reliable protective earth ground. All secondary circuits shall be connected to protective earth ground. Resistance of the ground returns to chassis shall not exceed 1.0 m Ω. This path may be used to carry DC-current. 4.2. HOT Swap Requirements Hot Swapping a power supply is the process of inserting and extracting a power supply from an operating power system. During this process the output voltages shall remain within the limits with the capacitive load specified. The hot swap test must be conducted when the system is operating under static, dynamic and zero loading conditions. The power supply can be hot swapped by the following method: Extraction: The power supply may be removed from the system while operating with PSON asserted, while in standby mode with PSON de-asserted or with no AC applied. No connector damage should occur during un-mating of the power supply from the power distribution board (PDB). Insertion: The power supply may be inserted into the system with PSON asserted, with PSON de-asserted or with no AC power present for that supply. No connector damage should occur due to the mating of the output and input connector. In general a failed (of by internal latch or external control) supply may be removed, then replaced with a good power supply, however, hot swap needs to work with operational as well as failed power supplies. The newly inserted power supply will get turned on into standby or Power On mode once inserted. 5.

Over Voltage Protection The PET front-ends provide a fixed threshold over voltage protection implemented with a HW comparator. Once an over voltage condition has been triggered, the power supply will shut down and latch the fault condition. The latch can be unlatch by disconnecting the supply from the AC mains or by toggling the PS_ON input. 5.2. Under Voltage Protection The main output will latch off when V1 drop to below the UV threshold. The latch can be unlatch by disconnecting the supply from the AC mains or by toggling the PS_ON input. The main output will shut down if the VSB voltage drop below 8V and recover when VSB voltage higher than 10 V.

Interfacing with Signals All signal pins have protection diodes implemented to protect internal circuits. When the power supply is not powered, the protection devices start clamping at signal pin voltages exceeding ± 0.5 V. Therefore all input signals should be driven only by an open collector/drain to prevent back feeding inputs when the power supply is switched off. If interconnecting of signal pins of several power supplies is required, then this should be done by decoupling with small signal schottky diodes as shown in examples in Figure 7 (except for SMB_ALERT, PW_OK pins). This will ensure the pin voltage is not affected by an unpowered power supply.

Front LEDs Status information is indicated by front-panel LED, LED is bi-colored: green and yellow. See Table 2 for different LED status. POWER SUPPLY CONDITION LED No AC power to all PSU OFF AC present/only standby output on 1 Hz Flashing Green Power supply DC output ON and OK Green Power supply failure Yellow Power supply warning 0.5 Hz Flashing Yellow*/Green* NOTE: * Flashing frequency: 1 Hz (0.5 sec Yellow/ 0.5 sec Green) Table 2 - LED Status 8.4. PS_ON The PS_ON signal is required to remotely turn on/off the main output of the power supply. PS_ON is and active low signal that turns on the main output power rail. When this signal is not pulled low by the system or left open, the outputs (except the Standby output) turn off. PS_ON is pulled to a standby voltage by a pull-up resistor internal to the power supply. 8.5. PWOK PWOK is a power good signal and shall be pulled HIGH by the power supply to indicate that all outputs are within regulation limits. When any output voltage falls below regulation limits, an internal failure or when AC power has been removed for a time sufficiently long, so that power supply operation is no longer guaranteed, PWOK will be de-asserted to a LOW state. The start of the PWOK delay time shall inhibited as long as any power supply output is in current limit. 8.6. SMB Alert The SMB_ALERT is an output signal and it is pulled to 3.3 V by a 4.7 K resistor in power supply. This signal indicates that the power supply is experiencing a problem that the user should investigate. This shall be asserted due to Critical events or Warning events. The signal shall activate in the case of critical component temperature reached a warning threshold, general failure, over-current, over-voltage, under-voltage, failed fan. This signal may also indicate the power supply is reaching its end of life or is operating in an environment exceeding the specified limits. 8.6.1. Thermal CLST SMB Alert shall also be utilized for warning of critical ther mal component temperatures. The Thermal CLST shall assert when the component temperature, which shall be reported by a dedicated thermal probe, is reaching below specified _T to critical shut down. The power supply shall report the temperature in addition to Thermal CLST through. 8.7. PDB_ALERT To receive ALERT signal from system or PSU backplane, If signal is pulled LOW, the PSU internal fan shall be forced to run at maximum speed to improve thermal performance. 8.8. PDB_FAULT To receive a FAULT signal from system or PSU backplane. PSU shall shutdown if this pin is pulled HIGH. 8.9. Current Share All outputs shall be capable of operating in a redundant current share mode. Eight power supplies may be operated in parallel. All outputs shall incorporate an isolation diode for fault isolation. Filter capacitors that are located after the isolation diode shall be of high reliability and shall be de-rated sufficiently to minimize failures. The +12 V current sharing shall be a single wire type. Connecting the ISHARE pins of each power supply together shall enable the current share feature. With the current share pins tied together, the output load current shall be balanced as defined below. The load share (ISHARE) shall be a single wire type. Connecting ISHARE pins of each PCM together shall enable the current
© 2015 Bel Power Solutions, Inc. 866.513.2839 tech.support@psbel.com belpowersolutions.com BCD.00505_AC share feature. With the current share pins tied together, the output load current shall be balanced to within 10% of full load (current difference should be less than 6.5 A). Shorting or opening of a current share pin shall not cause the output voltage to go out of steady state regulation. For 65 A the ISHARE voltage shall be 6 V for a single power supply. 8.10. Remote Sense Main output has sense lines implemented to compensate for voltage drop on load wires. The maximum allowed voltage drop is 200 mV on the positive rail and 200 mV on the output return rail. 8.11. I2C / PMBus Communication The interface driver in the PET supply is referenced to the V1 Return. The PET supply is a communication Slave device only; it never initiates messages on the I2C/SMBus by itself. The communication bus voltage and further characterized referenced in the Figure 8: There are 10K internal pull-up resistors The SDA/SCL IOs are 3.3/5 V tolerant Full SMBus clock speed of 100 kbps Clock stretching limited to 1 mS SCL low time-out of >25 mS with recovery within 10 mS Figure 8 - Physical layer of communication interface The SMB_ALERT signal indicates that the power supply is experiencing a problem that the system agent should investigate. This is a logical OR of the Shutdown and Warning events. Communication to the DSP or the EEPROM will be possible as long as the input AC voltage is provided. If no AC is present, communication to the unit is possible as long as it is connected to a life V1 output (provided e.g. by the redundant unit).

Graphical User Interface Bel Power Solutions provide with its “Bel power solutions I2C” a Windows® XP/Vista/Win7 compatible graphical user interface allowing the programming and monitoring of the PET800-12-074 Front-End. The utility can be downloaded on: www.belpowersolutions.com and supports both the PSMI and PMBus™ protocols. The GUI allows automatic discovery of the units connected to the communication bus and will show them in the navigation tree. In the monitoring view the power supply can be controlled and monitored. If the GUI is used in conjunction with the PET800-12-074 Evaluation Kit it is also possible to control the PS_ON pin(s) of the power supply. Figure 11 - Monitoring dialog of the I2C Utility 9. TEMPERATURE AND FAN CONTROL To achieve best cooling results sufficient airflow through the supply must be ensured. Do not block or obstruct the airflow at the rear of the supply by placing large objects directly at the output connector. The PET800-12-074 is provided with a normal airflow, which means the air enters through the DC-output of the supply and leaves at the AC- inlet. The fan inside of the supply is controlled by a microprocessor. The RPM of the fan is adjusted to ensure optimal supply cooling and is a function of output power and the inlet temperature. For the normal airflow version additional constraints apply because of the AC-connector. In a normal airflow unit, the hot air is exiting the power supply unit at the AC-inlet. The IEC connector on the unit is rated 100 ° C. . If 70 ° C mating connector is used then end user must derate the input power to meet a maximum 70 ° C temperature at the front, the rated output power should be 740W if input voltage less than 100VAC for PET800-12-074NA. don’t need derate for PET800-12-074RA. NOTE: It is the responsibility of the user to check the front temperature in such case. The unit will not limit its power automatically to meet such a temperature limitation.
