Sensor Switch Npp16 Nlight Power Pack Enclosed Energy Management Equipment 120/277 Vac

The nLight nPP16 family of power packs is the workhorse of an nLight 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 nLight 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 15 VDC. This power is typically utilized by other nLight 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. Besides switching, the nPP16 family has an optional 0-10V dimming output. This output can be directly wired to 0-10 VDC dimmable ballasts or LED drivers, and is fully isolated internally from ingress noise or line voltage faults. Models are available with dimming wires running through the chase nipple (nPP16 D) or out the side of the enclosure (nPP16 DS). The nPP16 ER and nPP16 D ER version relay packs provide a UL 924 compliant solution for controlling luminaires powered via an emergency circuit. Packs are wired to both normal and emergency power feeds. A unit only monitors the normal feed, while the emergency feed is connected to the line side of its relay. The power feed to emergency lighting is connected to the load side of the unit's relay. When normal power is present the relay is free to switch the emergency power feed as directed by sensors, switches, and schedules. However, if the normal power feed is lost the nPP16 (D) ER will override its relay closed and set its dimming output to full bright, thus ensuring emergency lighting is on. During this emergency operation period, the unit will not allow any switching or dimming to take place regardless of the presence of an occupancy,
