The BZ-50 Universal Voltage Power Pack provides 24 VDC operating voltage to WattStopper’s low-voltage occupancy sensors. This device is constructed with environmentally friendly materials and is RoHS-compliant. The BZ-50 consists of a high-efficiency switching power supply and a high-current relay. It has an input of 120/230/277 VAC, 50/60Hz, and an output of 24VDC, 225mA. It turns the connected load on and off automatically based on occupancy sensor input.  The BZ-50 Power Pack is comprised of Tefloncoated low-voltage leads and an ABS, UL 2043 and 94V-0 plastic resin enclosure that is plenum-rated. As a result, the BZ-50 does not require installation into the junction box, but can be cost-effectively installed directly into the plenum.  The BZ-50 Power Pack is designed to be flexible enough to control almost any lighting or HVAC load, such as lighting circuits, self-contained air conditioners, pumps, fans, motors, VAV systems, motorized damper controls and setback thermostats. The BZ-50 is well-suited for any application which requires high-voltage switching through low-voltage controls. By linking power packs and sensors, an almost unlimited number of configurations can be obtained.
