Fuji NC1S-2 Power Supply Module

The Fuji NC1S-2 converts AC line voltage into stable 5V and 24V DC outputs. This module supplies energy to the entire NC1 series backplane. It feeds CPU and I/O modules with clean, regulated power. Many system builders trust this unit for small to medium control racks.

Physical Layout and Connection Points

The Fuji NC1S-2 weighs 0.52 kilograms for secure mounting. Its 82 mm width fits standard NC1 racks perfectly. A three‑terminal connector accepts L, N, and ground wires. Two separate output headers provide 5V and 24V distribution. The front panel includes a green LED for power status confirmation. An internal 1200 µF capacitor stores energy for 20 milliseconds of hold‑up time.

Output Characteristics and Power Distribution

This power supply delivers 4 amperes on the 5V rail. The 24V rail provides 0.5 amperes for field devices. Therefore, calculate your total load before adding modules. The unit runs at 80% efficiency under normal conditions. Consequently, it produces moderate heat but requires no external fan. Keep the ambient temperature below 55°C for reliable operation.

Installation and Wiring Guidelines

Mount the Fuji NC1S-2 into the leftmost slot of the base board. First, disconnect AC mains supply completely before wiring. Then connect L, N, and ground wires to the input terminals. Use twisted pair cables for the DC output lines. The module automatically starts when you apply power. Wait for the green LED indicator to illuminate. After that, check both output voltages with a multimeter.

System Integration and Application Notes

This power supply works with any NC1 series CPU and I/O modules. It powers up to eight additional modules in a single rack. Do not connect external loads directly to the 5V output. Use the 24V rail for sensors or small relays instead. Typical applications include small assembly stations and test fixtures. For larger systems, add a second power supply module.
