5 Redundant power systems requiring parallel operation and hot-plug capability

6 Equipment needing remote monitoring and control via I2C/SMBus

注意事项 PRECAUTIONS

1 Airflow:RA model features reversed airflow (air enters AC inlet, exits DC output side); ensure no obstruction to airflow paths

2 Hot swap:Follow correct procedures—insert/extract only when allowed (e.g.,PSON asserted, standby mode, no AC applied) to avoid connector damage

3 Fan control:If PDB_ALERT pin is pulled LOW, the internal fan will run at maximum speed

4 Fault handling:The PSU will shut down if PDB_FAULT pin is pulled HIGH

5 Sense lines:Main output has remote sense lines to compensate for voltage drop (max allowed:200mV on positive rail and return rail)

6 I2C/SMBus:The PSU acts as a slave device only; SDA/SCL pins are3.3V/5V tolerant with10K internal pull-up resistors

7 EEPROM:2K bytes of user memory available; disable write protection via DSP command before writing, wait5ms after STOP condition before new START for write operations

8 Grounding:Ensure proper grounding with resistance ≤1.0mΩ between ground returns to chassis

9 Temperature:Operating ambient (inlet air) range is0~50°C; standby mode supports-5~50°C; non-operating range for RA model is-40~60°C

10 Safety:Do not repeat input-to-output electric strength tests in the field as it may void warranty

11 Connector:Use compatible mating connectors (FCI10035388-102LF or equivalent) for DC output
