Questions & Answers

Can I use this power pack with the LVSW-102-W? I want to use this switch to turn lights off/on. No occupancy sensor needed. If so, could you send me a wiring diagram. If not the correct power pack could you recommend one to use with this switch. Thank You

Asked by: Andrew
Hi, We recommend using the BZ-50 power pack for a LVSW-102 switch. Wiring diagrams and cut sheets are available within each product page under resources.

would the S120/277/347E-P relay pack be the correct relay pack for use in combination with a power pack (say: Wattstopper BZ-150) to switch a 208V (2P, line-to-line) lighting load controlled by an occupancy sensor? or is a 2P power pack available?

Asked by: Thierry
The S120/277/347E-P relay pack can be used in combination with other power packs as well as the BZ150 but the power consumption is either 120/277 or 347 and if you are trying to switch to 208 volts this will require a contactor.
