Output Design and Distribution

The Schneider ASBDNP210 delivers two regulated DC outputs for the PLC system. A +5 VDC rail provides 3.0 Amps for all backplane logic and CPU circuits. The +24 VDC output delivers 0.5 Amps for connected field sensors and small relays. Both outputs share a common return terminal for simplified wiring installation.

Power Performance Characteristics

This supply maintains 74% typical efficiency across its normal load range. It holds up the +5 VDC output for 18 milliseconds after input power loss. Consequently, your CPU continues operating through most momentary line disturbances. The unit draws a peak inrush current of only 15 Amps at 115 VAC.

Installation and Compatibility

Mount this power supply in the leftmost slot of any TSX Compact rack. The 5-pin terminal block accepts solid or stranded wires from 14 to 22 AWG. This module replaces earlier ASBDNP208 and ASBDNP209 units directly. You do not need any wiring changes or adapter plates for simple retrofits.

Energy Storage and Filtering

A 470 µF primary capacitor stores enough energy for the hold-up time specification. This capacitor also filters incoming AC line noise effectively. The supply requires no external batteries or additional energy storage devices. Therefore, you get a low-maintenance power solution for your Compact PLC system.

Thermal and Protection Features

The supply includes automatic overcurrent protection on both output rails. Short-circuit conditions will not damage the module or the backplane. An internal thermal limiter reduces output current if the internal temperature exceeds 80°C. A single green LED on the front panel indicates normal operation of all outputs.

Physical Design and Cooling

The compact 4.2 cm width saves valuable space in crowded control cabinets. Passive convection cooling eliminates the need for any internal fans. The 0.52 kg unit provides stable mounting without stressing backplane connectors. Therefore, this supply suits small machinery, conveyors, and standalone equipment perfectly.

Why Choose This Supply

Machine builders prefer this power supply for its universal 85–264 VAC input range. You can install this module anywhere worldwide without voltage selector switches. Therefore, this unit works perfectly for OEM applications and international machine exports.
