Fuji NP1S-22 Power Supply Module

Reliable DC Power for Your PLC Rack

This power supply module provides stable electrical power to all backplane cards. The Fuji NP1S-22 converts 24V DC input into regulated 5V DC for the system. It supplies up to 2.5A of continuous current to I/O and CPU modules. A green LED on the front panel indicates normal power output status. Consequently, this unit ensures reliable operation for your MICREX-SX automation system.

Input & Output Specifications

The Fuji NP1S-22 accepts a wide input voltage range from 20V to 28V DC. This flexibility allows operation from standard industrial 24V DC power supplies. The module delivers a steady 5V DC output with minimal electrical noise. Built‑in overload protection automatically shuts down during short circuits. A manual reset button restores normal operation after fault conditions clear.

Installation & System Integration

You insert the Fuji NP1S-22 into the dedicated power supply slot of your MICREX-SX rack. Connect 24V DC power to the two input terminals on the front panel. The module then distributes 5V DC to all backplane cards automatically. You can add up to 12 I/O modules in adjacent slots without additional power wiring. Therefore, this power supply simplifies system assembly significantly.

Operational Advantages & Reliability

The Fuji NP1S-22 includes a large capacitor for brief power interruption ride‑through. This feature prevents system resets during momentary voltage dips or spikes. The module runs silently without any cooling fan for maintenance‑free operation. An output OK LED allows instant visual verification of normal power status. Consequently, this Fuji power supply provides years of reliable service in industrial control cabinets.
