ABB 500PSM03a 1MRB 150038 R1 Rack Power‑Supply Module

‑ Input Voltage：88‑264 V AC，frequency 47‑63 Hz

‑ Rated Output Power：100 W，continuous output current 4.2 A

‑ Power Consumption：approx 11 W

‑ Mechanical Structure：Eurocard plug‑in board for Procontrol P13 rack, metal front panel, back‑plane bus connector, AC input terminal block

‑ On‑board Resources：AC‑DC conversion circuit, EMI filter circuit, over‑voltage / over‑current / short‑circuit / thermal protection unit, power‑supply monitoring sampling circuit, module self‑diagnosis unit, conformal coating protection layer

‑ Communication Interface：Internal dedicated local back‑plane bus for rack main processor

‑ Galvanic Isolation：galvanic isolation between AC input side and rack internal logic bus

‑ Protection：over‑voltage protection, over‑current protection, short‑circuit protection, thermal shutdown, input undervoltage alarm, inrush‑current limiting

‑ Status LED Indicators：Power indicator, Module Fault indicator, output status LED

‑ Weight：approx 0.95 kg

‑ Accepts wide‑range AC mains input, converts and filters to supply stable multi‑channel DC power to rack back‑plane bus for all plug‑in modules inside the cabinet.

‑ Supports multi‑module parallel redundant N+1 configuration; when one power‑supply unit fails, remaining units undertake full rack load without system shutdown.

‑ Real‑time monitors input voltage, output voltage, output current and internal temperature; triggers protection action under over‑voltage, over‑current, short‑circuit and overtemperature conditions.

‑ Module self‑diagnosis detects power‑supply internal fault, input power loss and back‑plane bus communication abnormality, uploads module‑level fault‑alarm information to main processor.

‑ Cannot run independently; must be installed inside Procontrol P13 rack and cooperate with back‑plane frame. 1MRB150038R1 is hardware revision variant of 500PSM03a series; pin‑compatible within 500PSM03a revision family, cannot directly interchange with other series power‑supply modules.

‑ Continuously monitors input power, output load state, internal temperature and module hardware health. Detected faults activate fault LED and send fault word to main processor.

‑ No local numerical display; power‑supply running status and fault codes are read via commissioning software or upper‑level HMI workstation.

‑ Under redundant configuration, single‑module hardware failure will not affect rack whole‑system operation; non‑redundant single‑unit failure will cause power loss of the whole rack and system stop running.

‑ Back‑plane connector：connects to Procontrol P13 internal local bus, transmits power‑supply diagnostic status to main processor.

‑ AC input terminal block：wiring terminals for site AC power source.

‑ Mounting：Plug‑in installation inside Procontrol P13 system rack

‑ Operating Temperature：‑20 °C ~ +60 °C，derating above +50 °C

‑ Storage Temperature：−40 °C ~ +85 °C

‑ Relative Humidity：5‑95 %RH, non‑condensing

‑ Protection Class：IP20 (cabinet internal)

‑ Power off the whole rack before inserting or removing this power‑supply module. Strictly confirm input voltage rating before power‑on; avoid wrong voltage input causing module burnout. For redundant configuration, match two modules of same hardware revision.

‑ For spare‑part replacement：Verify complete part number 1MRB150038R1. After replacement, confirm back‑plane bus identification, verify power‑output performance and fault‑reporting function. Mismatched power‑supply module will lead to unstable rack power supply.

‑ Module hardware fault will lead to power supply abnormality of whole rack.
