4.1 INPUT FUSE

Time-lag 20 A input fuse (5.4 x 22.5 mm) in series with the L -line inside the power supply protects against severe defects. The fuse is not accessible from the outside and is therefore not a serviceable part.

4.2 INRUSH CURRENT

The AC-DC power supply exhibits an X capacitance of only 4.7 µF , resulting in a low and short peak current, when the supply is connected to the mains. The internal bulk capacitor will be charged through a PTC which will limit the inrush current. NOTE: Do not repeat plug-in / out operations within a short time, or else the internal in -rush current limiting device (PTC) may not sufficiently cool down.

5.2 CLOSED LOOP STABILITY

The power supply shall be unconditionally stable under all line/load/transient load conditions including capacitive load ranges. A minimum of: 45 degrees phase margin and -10dB-gain margin is required. The power supply manufacturer shall provide proof of the unit’s closed-loop stability with local sensing through the submission of Bode plots. Closed -loop stability must be ensured at 10%, 20%, 50% and 100% loads as applicable, 0% is just for reference.

5.3 RESIDUAL VOLTAGE IMMUNITY IN STANDBY MODE

The power supply should be immune to any residual voltage placed on its outputs (Typically a leakage voltage through the system from standby output) up to 500mV. There shall be no additional heat generated, nor stressing of any internal components with this vo ltage applied to any individual or all outputs simultaneously. It also should not trip the protection circuits during turn on. The residual voltage at the power supply outputs for no load condition shall not exceed 100mV when AC voltage is applied and the PSON_L signal is de-asserted.

5.4 COMMON MODE NOISE

The common mode noise on any output shall not exceed 350mV pk-pk over the frequency band of 10Hz to 20MHz. The measurement shall be made across a 100 Ω resistor between each of DC outputs, including ground at the DC power connector and chassis ground (power subsystem enclosure), the test set -up shall use a FET probe such as Tektronix model P6046 or equivalent.

5.5 SOFT STARTING

The Power Supply shall contain control circuit which provides monotonic soft start for its outputs without overstress of the AC line or any power supply components at any specified AC line or load conditions.

5.6 ZERO LOAD STABILITY REQUIREMENTS

When the power subsystem operates in a no load condition, it does not need to meet the output regulation specification, but it must operate without any tripping of over-voltage or other fault circuitry. When the power subsystem is subsequently loaded, it must begin to regulate and source current without fault.

5.7 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 shall use a latching mechanism to prevent insertion and extraction of the power supply when the AC power cord is inserted into the power supply.

5.8 FORCED LOAD SHARING

The PES front-ends have an active current share scheme implemented for V1. All the ISHARE current share pins need to be interconnected in order to activate the sharing function. If a supply has an internal fault or is not turned on, it will d isconnect its ISHARE pin from the share bus. This will prevent dragging the output down (or up) in such cases. The current share function uses an analog bus to transmit and receive current share information. The controller implements a Master/Slave current share function. The power supply providing the largest current among the group is automatically the Master. The other supplies will operate as Slaves and increase their output current to a value close to the Master by slightl y increasing their output voltage. The voltage increase is limited to +250 mV. The output will share within 10% at full load. The 12VSB output is not required to actively share current between power supplies (passive sharing).

9.2 EEPROM PROTOCOL

The EEPROM follows the industry communication protocols used for this type of device. Even though page write / read commands are defined, it is recommended to use the single byte write / read commands. WRITE The write command follows the SMBus 1.1 Write Byte protocol. After the device address with the write bit cleared a first byte with the data address to write to is sent followed by the data byte and the STOP condition. A new START condition on the bus should only occur after 5ms of the last STOP condition to allow the EEPROM to write the data into its memory. READ The read command follows the SMBus 1.1 Read Byte protocol. After the device address with the write bit cleared the data address byte is sent followed by a repeated start, the device address and the read bit set. The EEPROM will respond with the data byte at the specified location.

9.3 PMBus® PROTOCOL

The Power Management Bus (PMBus®) is an open standard protocol that defines means of communicating with power conversion and other devices. For more information, please see the System Management Interface Forum web site at: www.powerSIG.org. PMBus® command codes are not register addresses. They describe a specific command to be executed. The PES1600-12-080NA supply supports the following basic command structures:

  • Clock stretching limited to 1 ms
  • SCL low time-out of >25 ms with recovery within 10 ms
  • Recognized any time Start/Stop bus conditions WRITE The write protocol is the SMBus 1.1 Write Byte/Word protocol. Note that the write protocol may end after the command byte or after the first data byte (Byte command) or then after sending 2 data bytes (Word command). In addition, Block write commands are supported with a total maximum length of 255 bytes. READ The read protocol is the SMBus 1.1 Read Byte/Word protocol. Note that the read protocol may request a single byte or word. In addition, Block read commands are supported with a total maximum length of 255 bytes.

9.4 POWER SUPPLY DIAGNOSTIC “EVENT RECORDER”

The power supply shall save the latest data and other pertinent data into nonvolatile memory when a critical event shuts down the power supply. This data shall be accessible via the PMBus® interface with an external source providing power to the 12Vstby output. Critical Events to trigger an update to the Event Recorder includes:

  • Output OVP
  • Output OCP
  • Input OV/UV Fault
  • Fan fault
  • OTP
  • Other faults to cause output shutdown. Refer to BCA.00199_PES1600-12-080NA PMBus® Communication Application Note for further information about the PMBus® commands to support this function.

9.5 FIRMWARE UPDATE

The power supply shall have the capability to update its firmware via the PMBus® interface while it is in standby mode. This FW can be updated when in the system and in standby mode and outside the system with power applied to the 12Vstby pins. BPS standard GUI supports the firmware upgrade function.

9.6 GRAPHICAL USER INTERFACE

Bel Power Solutions provides with its “I2C Utility” a Windows® XP/Vista/Win7 compatible graphical user interface allowing the programming and monitoring of the PES1600-12-080NA Front-End. The utility can be downloaded on: belfuse.com/power-solutions 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 YTM.00103 Evaluation Board it is also possible to control the PSON_L pin(s) of the power supply.
