Product Short Description
Product Name: Modicon AS-P830-000, 800 Series 24 VDC Power Supply Module
Product Introduction: The AS-P830-000 is a rugged, industrial-grade power supply module belonging to the legacy Modicon 800 Series PLC family, originally developed by Gould/Modicon and now part of Schneider Electric. It is designed to provide stable, regulated 24 VDC power to the PLC backplane, supporting the operation of processor modules and I/O cards in large-scale control systems.

Functional Features: The module utilizes a linear or early switching regulator design to convert raw AC power into clean, ripple-free 24 VDC. It includes sophisticated filtering circuitry to suppress EMI and RFI, which is critical for preventing logic errors during motor starts or switching events. It acts as the core power distribution component across the backplane pins.
Application Scenarios: Widely used in heavy industry — automotive manufacturing (assembly lines, robotic welding cells), steel mills (rolling mill control), water treatment (pumping stations, filtration), and chemical processing (batch processing, safety interlock systems).
Operating Principle: Converts field-selectable AC input (115/230 VAC) into regulated 24 VDC through a linear or early switching regulator, then distributes filtered power across the 800 Series rack backplane to all connected modules.
Installation Requirements: Before applying power, ensure the input voltage jumper or switch matches local utility (115V or 230V). Slide the module into the dedicated power supply slot of the 800 Series rack and secure the mounting screws to guarantee mechanical and ground connection to the backplane. Connect AC line, neutral, and ground wires to the specified terminal block using appropriately rated wire gauges.
Usage Precautions: Upon energizing, verify the “Power” LED is illuminated. If off, check primary fuses or backplane load for potential short circuits. The unit is proprietary to the Modicon 800 Series mechanical and electrical backplane architecture and is not compatible with Quantum Series PLCs.
