The night nPP16 family of power packs is the workhorse of an night system, delivering robust system performance and design versatility for commercial and industrial lighting control applications. The nPP16 family is capable of switching loads up to 16 Amps via an internal latching relay designed with robust protection from the harsh switching requirements of T5 fluorescent and LED loads. These power packs also provide night system bus power - up to 40mA from each of its two RJ-45 ports - by transforming Class 1 line voltage (120/277 VAC or 347 VAC) to Class 2 low voltage (15 VDC). This power is typically utilized by other night devices within the power pack's local control zone, however, remaining power is also made available over the network for Bridges and devices in other zones to utilize.
