System compatibility39PSR4ANEN is compatible with SIEMENS MOORE APACS+ and QUADLOG safety DCS. It supplies power to rack-based ACM controllers, QLCCM safety processors and all I/O modules within the rack.

FunctionThis 400W power supply rack converts AC mains input to regulated 24VDC power for the entire DCS rack assembly. It delivers stable power to processor cards, analog & discrete I/O modules and communication boards. Built-in power monitoring circuit detects undervoltage, overload and short-circuit faults to protect the whole rack hardware.

InstallationCut off AC power before installation. Install the power rack into the APACS/QUADLOG cabinet chassis. Connect AC input wiring to terminal block, then connect internal 24VDC distribution bus to rack backplane. Apply power and verify output voltage before loading controller and I/O modules.

InterfaceAC input screw terminals, 24VDC backplane power connector, front LED indicators for power ok, fault status.

Feature400W high capacity rack power unit, automatic 115/230V AC input selection, overload, short circuit and overvoltage protection, built-in power health monitoring. Obsolete legacy spare part, used for APACS+ / QUADLOG DCS rack power system maintenance and replacement.

DiagnosticNo power output: check AC input wiring, fuse and mains supply. Power fault LED on: inspect for short circuit on backplane or module overload. Intermittent dropout: verify terminal tightness and cooling ventilation.

Product BriefSIEMENS MOORE 39PSR4ANEN is 400W rack mount power supply for APACS+ and QUADLOG DCS, widely used in petrochemical, power and pulp & paper industries to provide 24VDC power for control rack hardware.
