Product Details

Modicon AS-P930-001, commonly shortened and ordered as ASP930001, is a rugged rack mount power supply module and reliable backplane power unit belonging to the Modicon 900 series legacy power lineup under AEG Modicon. This plc chassis power module is designed to plug directly into the 900-series backplane and deliver stable regulated DC power to the chassis CPU, discrete I/O, analog modules and communication adapters. It accepts universal AC mains input and converts it into clean, low ripple DC power required by sensitive control electronics. Front panel LED indicators clearly display power good, overload and fault status for rapid visual diagnosis, while heavy-duty screw terminals simplify mains wiring. Built with industrial-grade components and internal EMI filtering, it can run continuously under fluctuating power, vibration and dust conditions common in process plants. As a discontinued legacy spare, this rack mount power supply module serves as a drop-in replacement to restore stable backplane power distribution for ageing Modicon 900 automation racks.

Supported Functions

This rack mount power supply module supplies continuous regulated power across the entire chassis backplane. The backplane power unit maintains steady output voltage during transient load changes caused by I/O switching. This plc chassis power module integrates complete protective circuits including overcurrent shutdown, overvoltage clamping and thermal cut-off to protect the CPU and I/O modules from electrical damage. It continuously monitors its internal operating state and signals fault conditions over the backplane for system diagnostics. It works in tandem with Modicon 900 CPUs, analog cards, discrete I/O and remote I/O adapters to sustain reliable operation of the whole legacy control system.

Core Functions

As the central backplane power source, this rack mount power supply module converts AC line power into the regulated DC power required by all plugged-in control modules. Its built-in filtering suppresses conducted noise from factory power lines and limits fault spread across the backplane. This backplane power unit acts as a direct spare to rebuild stable chassis power feed for ageing Modicon automation racks.
