Output Design and Distribution

The Schneider ASBDNP023 delivers two regulated DC outputs for the PLC system. A +5 VDC rail powers all backplane logic and CPU circuits. The +24 VDC output provides energy for connected field sensors and small relays. Both outputs share a common return terminal for simplified wiring.

Power Performance Characteristics

This supply maintains 72% typical efficiency across its normal load range. It holds up the +5 VDC output for 15 milliseconds after input power loss. Consequently, your CPU continues operating through most momentary line disturbances. The unit draws a peak inrush current of only 12 Amps at 115 VAC.

Installation and Compatibility

Mount this power supply into any TSX Micro or Compact rack slot. The 4-pin terminal block accepts solid or stranded wires from 16 to 22 AWG. This module replaces earlier ASBDNP022 and ASBDNP021 units directly. You do not need any adapter plates or wiring changes for retrofits.

Energy Storage and Filtering

A 220 µF primary capacitor stores enough energy for the hold-up time specification. This capacitor also filters incoming AC line noise and reduces output ripple. The supply requires no external batteries or additional storage devices. Therefore, you get a low-maintenance power solution for your compact PLC.

Thermal and Protection Features

The supply includes automatic overcurrent protection on both output rails. Short-circuit conditions will not damage the module or connected equipment. An internal thermal limiter reduces output current if the internal temperature exceeds 75°C. A single green LED on the front panel indicates normal operation of all outputs.

Physical Design and Space Savings

The compact 3.8 cm width saves valuable space in crowded control cabinets. You can mount this unit vertically or horizontally without performance changes. The lightweight 0.35 kg design puts minimal stress on the backplane connectors. Therefore, this supply suits small machinery, conveyors, and standalone equipment.

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.
