Power Conversion and System Role

This power supply module provides reliable DC power for Schneider control systems. It converts 120/240 VAC input into 24 VDC output for field I/O. The module delivers 10 A continuous current for demanding automation applications. Overload and short-circuit protection safeguard connected equipment from damage. Consequently, this unit ensures stable system operation in industrial environments.

Technical Specifications

Power Conversion and Output Regulation

The AS810000 converts AC mains into a tightly regulated 24 VDC output. It delivers 10 A continuously for powering multiple I/O modules and field devices. The module maintains output voltage within ±0.5% across varying loads. Internal filtering reduces ripple to less than 100 mV peak-to-peak. This clean power ensures reliable operation of sensitive control electronics.

Protection Features and Fault Tolerance

The module includes comprehensive protection for safe and reliable operation. Overcurrent protection limits output current during short-circuit conditions. Overvoltage protection prevents damage to connected devices from voltage spikes. An internal thermal sensor shuts down the unit during overtemperature events. These features enhance system reliability and reduce downtime.

Input Power Connection and Configuration

The module accepts 120 VAC or 240 VAC through a selector switch. Screw terminals provide secure connections for input and output wiring. The unit includes an internal fuse for input overcurrent protection. Connect the ground terminal to the system earth ground point. Always verify the selector switch matches the supply voltage before power-up.

Installation and Mounting Instructions

Mount the power supply on a 35 mm DIN-rail using the integrated clips. Alternatively, secure it to a panel using the mounting flanges. Ensure adequate clearance for airflow and cable access. Connect input and output wiring with properly sized cables. Tighten all terminal screws to 0.5–0.6 Nm for reliable connections.

Thermal Performance and Cooling

The module uses natural convection cooling without an internal fan. This design eliminates fan noise and maintenance requirements. The unit operates reliably from –20°C to +60°C ambient temperatures. Users should maintain clearance around the module for proper heat dissipation. Derate output current by 2.5% per °C above 50°C.

Construction Quality and Durability

The power supply uses industrial-grade components for long service life. The housing features rugged construction with corrosion-resistant finish. All terminal blocks use plated contacts for reliable connections. This robust design suits demanding factory floor and process plant environments. The unit meets all relevant safety and EMC standards.

Maintenance and Service Guidelines

Inspect terminal connections periodically for tightness and oxidation. Clean the unit using compressed air to remove dust buildup. Monitor the Power OK LED for normal operation status. Replace the module immediately if the output voltage becomes unstable. Keep the ventilation openings unobstructed for proper cooling.
