Replace Aging Power Supplies with the Schneider AS-P120-000
Downtime from a failed power supply cripples production. The Schneider AS-P120-000 power supply module restores dependable power to Modicon control systems. This unit accepts 115/230V AC input and delivers 0.6A at 115V or 0.3A at 230V. It mounts on a standard DIN rail and weighs just 0.44 lbs (0.20 kg). The AS-P120-000 belongs to the Modicon product line and carries an IP20 protection rating for internal use.
Key Technical Parameters That Matter
Voltage Flexibility Across Systems
The AS-P120-000 operates on both 115V and 230V AC networks. This dual-range capability simplifies inventory because one module serves different plant voltages. The current draw adjusts automatically: 0.6A at 115V and 0.3A at 230V.
Temperature Resilience in Harsh Environments
This module functions from -25°C to 55°C. Storage tolerance extends from -40°C to 85°C. Such wide ranges suit unheated cabinets, rooftop enclosures, and process areas with varying climates.
Compact DIN Rail Mounting
The DIN rail mount saves panel space and speeds replacement. Technicians swap the unit without drilling new holes or fabricating brackets.
Solving Real Engineering Pain Points
Pain Point: Obsolete Power Modules Halt Production
Legacy Modicon systems often rely on discontinued power supplies. The AS-P120-000 offers a direct-fit replacement path. Its 115/230V AC input matches common control voltages. The DIN rail mount aligns with standard enclosures. When a supply fails, you restore power quickly instead of waiting weeks for a custom build.
Pain Point: Voltage Mismatch Across Global Facilities
Plants in different regions use different mains voltages. The AS-P120-000 handles both 115V and 230V AC without a selector switch or jumper change. Maintenance teams stock one part number for multiple sites. This reduces spare-parts inventory and simplifies procurement.
Pain Point: Temperature Extremes Cause Random Shutdowns
Power supplies that lack thermal headroom fail unpredictably in hot or cold areas. The AS-P120-000 operates from -25°C to 55°C. That range covers most industrial control rooms and outdoor cabinets. You avoid nuisance trips and extend service life.
Installation and Setup Guidance
Mount the AS-P120-000 on a standard DIN rail inside a protective enclosure. The IP20 rating means the module requires a clean, dry environment free from conductive dust and moisture. Follow Schneider Electric’s official installation manual for wiring and torque specifications. Do not exceed the rated input voltage or current. Verify that the enclosure provides adequate ventilation to keep ambient temperature within the operating range.
Maintenance and Reliability for Long-Term ROI
Inspect the module periodically for loose connections, dust accumulation, and signs of overheating. Because the unit has no moving parts, wear is minimal. However, electrolytic capacitors age over time, especially in high-temperature environments. Keep spare units on hand to minimize downtime. The wide storage temperature range allows long-term warehousing without degradation. This reliability translates to lower total cost of ownership and fewer unplanned outages.
Compatibility and Integration with Modicon Systems
The AS-P120-000 belongs to the Modicon product line. It integrates with Modicon control and automation systems that require a 115/230V AC power supply. The module’s DIN rail mount fits standard enclosures used in Modicon installations. Always verify compatibility with your specific chassis and I/O configuration before ordering.
Selection Guide: What to Verify Before Buying
Before purchasing the AS-P120-000, confirm your system’s input voltage (115V or 230V AC) and current requirements. Check that the DIN rail type matches your panel. Ensure the operating temperature range suits your environment. The IP20 rating limits use to indoor, protected locations. For availability and replacement options, contact SpareTechPLC. They specialize in industrial automation parts and can confirm current lifecycle status.
