The module measures 105 mm in width and 85 mm in height. Its total depth reaches 75 mm. The FUJI NP1PS-81 weighs approximately 550 grams. This unit contains a switching power supply PCB with input filtering. Energy storage uses large electrolytic capacitors for 20 ms hold-up time.

You will find a removable terminal block on the bottom edge. A green LED indicates normal output operation. A red LED lights up during fault conditions. Consequently, you can diagnose power issues quickly without a meter.

Installation and System Integration

You can mount the FUJI NP1PS-81 directly into the first slot of a MICREX-F rack. The module requires an external AC source with proper circuit protection. Therefore, install a breaker on the input line. The backplane distributes power to all other modules automatically.
