N: Normal R: Reversed Input A: AC The PET1300-12-054xA AC/DC power supply is a fully DSP controlled, highly efficient front-end power supply. 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 operational voltage range and minimal linear derating of output power with input voltage and temperature, the PET1300-12-054xA maximizes power availability in demanding server, network, and other high availability applications. The supply is fan cooled and ideally suited for integration with a matching airflow paths. The PFC stage is an analogue solution; MCU is used to communicate with DSP chip on secondary side. The DC/DC stage uses soft switching resonant techniques in conjunction with synchronous rectification. An active OR-ing device on the output ensures no reverse load current and hence it is ideally suited for operation in redundant power systems. The always-on standby output with voltage level (3.3 Volts), 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 LEDs. In addition, the power supply can be controlled and the fan speed set via the I2C bus. The I2C bus 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.

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.

This signal indicates that the power supply is experiencing a problem that the user should investigate. This may be asserted due to Critical events or Warning events. See PMBUS specification for further details. Interconnect Diagram of SMB_ALERT_L Signal This is an input signal and is used to force the 12 V main output off if the supply is removed from the system. At the system level this pin will be connected to the output return directly. When this input is low the power supply will operate. If the input is floating the 12 V main output will turn off while the 3.3 VSB will remain on. This signal overrides all other on-and-off signals. On the power supply connector, this pin is shorter than the others so it is a last-make and first-break contact. See below Table 3 for Logic Table. Interconnect Diagram of PSKILL_H Signal

Pull-up to 3.3 VSB located in the power supply. PS_KILL = Low, PS_ON = Low ON PS_KILL = Open, PS_ON = Low or Open OFF PS_KILL = Low, PS_ON = Open OFF MIN MAX Source current, Vps_kill =Low 4 mA The PS_ON_L signal is an input signal used to remotely turn on/off the power supply. PS_ON_L is an active LOW signal that turns on the 12 V main output. In the low state this input will not source more than 4 mA of current. The 12 V output will be disabled when this input is driven HIGH, or open circuited. See Table 4 for Logic Table. Interconnect Diagram of PSON_L Signal Table 4 - PS_ON_L Signal Characteristics SIGNAL CHARACTERISTICS Signal Type: Input signal to the power supply Accepts an open collector/drain input from the system. Pull-up to 3.3 VSB located in power supply. PS_ON_L = Low, PS_KILL = Low ON PS_ON_L = Open, PS_KILL = Low or Open OFF PS_ON_L = Low, PS_KILL = Open OFF MIN MAX Output Source Current, VPS_ON_L= Low 4 mA PW_OK is an output signal and will be pulled HIGH by the power supply to indicate that all the outputs are within the regulation limits of the power supply. When 12 V main output is < 10.9 V or > 13.2 V, or if any of the outputs fail due to over current protection, over voltage protection, over temperature, or fan failure then this output will be driven LOW. In the event when AC mains power is lost, this signal will be driven LOW at least 20 mS before the +3.3 VSB output is lost. The output will be an open collector/drain. The start of the PW_OK delay time shall be inhibited as long as any power supply’s 12 V output is in current limit. See Table 5.

After falling outside the input voltage requirements for more than 20 mS, the signal must be driven LOW. The output will be an open collector/drain. See below Table 6.

© 2015 Bel Power Solutions, Inc. 866.513.2839 tech.support@psbel.com belpowersolutions.com BCD.00420_AE All outputs shall be capable of operating in a redundant current share mode. A maximum of 6 power supplies may be operated in parallel. All outputs shall incorporate an isolation device (Or-ing MOSFET or diode) for fault isolation. Filter capacitors that are located after the isolation device shall be of high reliability and shall be de-rated sufficiently to minimize failures. The 3.3 V output current sharing shall be of a droop type. The +12 V current sharing shall be a single wire type, active current sharing. Connecting the Ishare (current share) pins of each power supply together shall enable the current share feature. Shorting or opening of a current share pin shall not cause the output voltage to go out of steady state regulation. For 12 V output the Ishare (load sharing) voltage shall be a linear function Ishare [V] = 8 x Iout/108 (with 8 V at 108 A) for a single power supply (~74 mV/A). At light load, the load share becomes difficult because of low feedback signal. Refer to Table 2 for current sharing accuracy. The current balance accuracy is calculated as: 2*|I1-I2|/ (I1+I2), where the I1 is the PSU1 load current and I2 is the PSU2 load current. The outputs specified shall incorporate remote sense and will compensate for specified load cable drop. In the event of loss of remote sense, all outputs shall revert to internal sense so as to limit the outputs to less than 105% of nominal. Unless defined otherwise, all control signals shall be TTL compatible with respect to the output return and shall be isolated from the primary circuit and be SELV rated. All input signals shall be driven from an open collector with the pull-up resistor located in the power supply and shall be capable of sourcing up to 4 mA. General LVTTL signal levels are specified in below table except where explicitly specified otherwise.
