Schneider Electric NF120PSG3L Power Interface Module

Schneider Electric NF120PSG3L Power Interface Module is an externally powered 120 V Powerlink G3 power supply designed to energize the Powerlink control bus in NF panelboards. Housed in a surface-mount NEMA 1 enclosure with cover, it mounts like a standard circuit breaker and provides voltage to the Powerlink G3 network. The unit includes LEDs for line voltage and the C-Bus network, enabling quick status checks, and it can source up to 700 mA to the C-Bus network, supporting multiple devices on the Powerlink system. It is available in configurations for 121 V or 277 V AC systems, and a UTP connection jumper is included to support dual-supply installations. The NF120PSG3L is the externally powered option (as opposed to the NF120PSG3 panel-bus powered version) and works with Powerlink G3 control buses to interface between the system controller and the network, including operation of ECB remotely operated circuit breakers and Powerlink controllers within Square D Powerlink installations. This module is part of Schneider Electric’s Powerlink G3 family and is designed for use in NF panelboard environments where a local external power source is required to energize the Powerlink network.
