The module measures 105 mm in width and 85 mm in height. Its total depth reaches 70 mm. The FUJI NP1S-81 weighs approximately 520 grams. This unit contains a switching power supply PCB with input filtering and output regulation. Energy storage uses large electrolytic capacitors for hold-up during short interruptions.
You will find a removable terminal block on the bottom edge. A green LED indicates normal output status. 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 NP1S-81 directly into the first slot of a MICREX-F rack. The module requires an external AC source for operation. Therefore, you need proper circuit protection on the input side. The passive backplane distributes power to all other modules automatically.
