Introduction
Downtime in a control cabinet often starts with a power supply that no longer meets the demands of the system. The AS-P120-000 from Schneider Electric addresses this exact pain point. This Modicon power supply module converts a 115/230V AC input into a stable supply for compatible automation hardware. With a weight of only 0.44 lbs (0.20 kg), it adds minimal load to a DIN rail assembly. Engineers who maintain legacy Modicon installations will recognize this module as a practical replacement option when original units fail or become hard to source.

Technical Specifications That Matter
The AS-P120-000 carries a voltage rating of 115/230V AC. This dual-range input lets the same module operate in facilities with different mains standards. At 115V, the current rating reaches 0.6A. At 230V, the current rating is 0.3A. That difference reflects the constant power demand of the connected load, so technicians can verify branch circuit capacity before installation.
Environmental tolerance is another strong point. The module operates between -25°C and 55°C, covering most industrial control rooms and process cabinets. Storage limits extend from -40°C to 85°C, which protects the unit during shipping or long-term warehousing. The IP20 protection rating means the enclosure resists solid objects larger than 12.5 mm but does not seal against water. DIN rail mounting simplifies replacement because technicians can swap the unit without drilling new panel holes.

Where This Module Fits
Replacing Failed Power Supplies in Legacy Panels
Many compact 984 and A210 chassis systems still run critical processes. When their original power supply fails, a direct-fit module like the AS-P120-000 keeps the line running. The DIN rail mount and 115/230V AC input reduce the time a maintenance team spends on the swap.
Supporting Modicon I/O Racks
The Modicon product line includes I/O and chassis hardware that depends on a stable supply. This module belongs to the 18130-COMPACT 984 A210 I/O & CHASSIS category, so it aligns with those assemblies. A technician can restore power to an I/O rack without redesigning the cabinet.
Operating in Harsh Plant Environments
Temperature swings challenge electronics in remote cabinets or unheated buildings. The -25°C to 55°C operating range lets the module function in cold storage areas and warm process rooms alike. The IP20 rating suits clean, dry enclosures where dust and moisture stay controlled.
Installation and Setup
DIN rail mounting makes the physical installation straightforward. Clip the module onto a standard rail, then verify that the rail is clean and free of burrs. Because the unit accepts 115/230V AC, confirm the actual mains voltage at the panel before applying power. Match the branch circuit to the current rating: 0.6A at 115V or 0.3A at 230V. Keep the module inside an enclosure that maintains the IP20 environment. Do not expose it to dripping water or conductive dust. Follow all local electrical codes and the manufacturer’s documentation during wiring.
Maintenance and Reliability
A power supply module has no moving parts, so wear mainly affects external connections and surrounding components. Inspect terminal screws periodically for tightness. Check for discoloration or heat marks that could indicate an overload. Keep the cabinet filter clean so airflow remains adequate. Because the storage range reaches 85°C, a spare unit can sit on a shelf for years without damage. That makes the AS-P120-000 a sensible item to stock for critical Modicon systems. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
Compatibility and Integration
The module belongs to the Schneider Electric Modicon family and the 18130-COMPACT 984 A210 I/O & CHASSIS category. It integrates with compatible Modicon chassis and I/O hardware that expects a 115/230V AC supply. The DIN rail format fits standard enclosures, so it drops into existing panel layouts. The GTIN 3595861130708 helps buyers confirm they receive the correct unit. Country of origin is DE.
Selection Guide
Before you buy, confirm the input voltage at your site and the current demand of the connected load. Verify that your enclosure provides an IP20 environment and a standard DIN rail. Check that your Modicon chassis or I/O rack matches the 18130-COMPACT 984 A210 category. Note that this item is not returnable, so accuracy matters. SpareTechPLC supplies industrial automation parts and can help you confirm fitment before purchase.
