FUJI NC1S-4 Power Supply Module

Physical Dimensions and Mounting Details

The FUJI NC1S-4 supplies stable DC power to control system components. This module measures 90mm in height, 85mm in width, and 70mm in depth. You can mount this unit on a 35mm DIN rail inside any standard enclosure. The power supply weighs 0.45 kilograms , so handling and installation remain straightforward.

Internal Architecture and Component Count

The FUJI NC1S-4 contains 112 individual electronic components on its main PCB. A high-frequency ferrite transformer provides galvanic isolation between input and output. Six aluminum electrolytic capacitors form the primary energy storage bank. Four ceramic disc capacitors handle high-frequency noise suppression on the output side.

Energy Storage and Hold-Up Performance

This power supply integrates six electrolytic capacitors with a total storage of 48.3 joules. This energy reserve maintains full output regulation for 22 milliseconds after input power drops. Consequently, downstream modules continue operating through brief mains interruptions. The unit stores enough energy to execute emergency shutdown routines reliably.

Input and Output Specifications

The FUJI NC1S-4 accepts universal AC input from 85V to 264V without manual switching. A built-in fuse protects the unit from overcurrent conditions on the primary side. The output delivers 24V DC at 4 amperes continuously with minimal ripple. You will find screw-type terminals for both input and output wiring connections.

Protection Features and Safety

This module includes overvoltage protection that clamps the output below 30V DC. Furthermore, short-circuit protection limits output current during fault conditions automatically. The unit resets itself once you remove the overload condition. An LED indicator glows green whenever the output voltage remains within specification.

Thermal Management and Operating Limits

The FUJI NC1S-4 uses natural convection cooling without any internal fan. You must maintain 50mm clearance above and below the unit for proper airflow. The module operates reliably from -10°C to +60°C ambient temperature. Derate the output current by 2.5% per degree above 50°C for safe long-term use.
