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.

6.3 GRAPHICAL USER INTERFACE

Bel Power Solutions provide with its “Bel Power Solutions I²C Utility” a Windows® XP/Vista/Win7 compatible graphical user

interface allowing the programming and monitoring of the PET1300-12-054xA 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.

6.4 PRESENT_L

The PRESENT_L is an output signal and it is used to sense the number of power supplies in the system (operational or not).

This signal is connected to the power supply’s output ground. Electrical characteristics see 6.2.

Figure 8. Interconnect Diagram of PRESENT_L Signal

6.5 SMB_ALERT_L

The SMB_ALERT_L is an output signal and shall be an open collector with the pull-up resistor located at the receiving end and

shall capable of sinking up to 4 mA.

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.

Figure 9. Interconnect Diagram of SMB_ALERT_L Signal

6.6 PSKILL_H

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.

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.

6.8 PW_OK

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.

CURRENT SHARING

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.

6.11

REMOTE SENSE

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.
