VMIC 332-000132-B VME Chassis Power Supply Module

Module Feature

332-000132-B is a single-slot 6U VMEbus chassis power supply module developed by VMIC (GE Fanuc / Abaco Systems),designed to provide regulated multi-rail power for full VME backplane and all plugged-in VME functional boards. It supports universal AC input 115/230 V AC or optional 24/48 V DC input variant. Output rails include +5 V DC main power, +12 V DC and -12 V DC auxiliary power, total power rating from 300 W up to 500 W depending on hardware revision. Built-in complete protection circuit: overvoltage protection(OVP), overcurrent protection(OCP), overtemperature protection(OTP). When any fault condition triggers,the power supply shuts down output immediately and latches fault state. Integrated BIT diagnostic circuit monitors output voltage,output current and internal temperature continuously,front panel LED indicates power good and fault alarm status. Rugged Eurocard PCB with conformal coating,shock and vibration screened for power plant cabinet environment,widely used in gas/steam turbine VME control rack,aerospace ground test bench and multi-board hardware-in-loop simulation VME chassis.

Working principle

AC or DC input power enters EMI filter first,then converted by switching power topology into stabilized +5 V, +12 V and -12 V DC power for VME backplane distribution. OVP, OCP and OTP circuits continuously sample output and internal temperature; once threshold exceeded,power output cuts off to protect downstream VME boards. BIT circuit samples each rail voltage and temperature sensor,updates status register and front panel LED state.

Installation

Follow ESD safety procedure before handling.Fully power off VME chassis.Insert 332-000132-B into dedicated 6U VME power slot and lock front panel ejector latches.Connect main input power cable to front panel inlet.Power on chassis,run BIT power rail diagnostic before commissioning.

Interface

VME J1/J2 backplane connector,front-panel main power input connector,power status register pins.

Diagnostic

Board undetected: power module does not occupy VME address space. No output power: input power missing or OTP/OVP latched fault. Intermittent voltage drop: overload or fan cooling failure. Fault LED lit: overcurrent,overvoltage or overtemperature detected by BIT circuit.
