BZ-250 – LIGHTING & PLUG LOAD FLEX CONTROL POWER PACK

$65.00$80.00

THE BZ-250 CAN CONTROL LIGHTING CIRCUITS, PLUG LOAD CIRCUITS, SELF-CONTAINED AIR CONDITIONERS, PUMPS, FANS, MOTORS AND MOTORIZED DAMPER CONTROLS. BI-LEVEL SWITCHING WITH MANUAL-ON OPERATION CAN BE ACHIEVED USING TWO LOW-VOLTAGE SWITCHES, A CEILING SENSOR AND TWO BZ-250S (ONE SET TO AUTO-ON AND ONE SET TO MANUAL-ON). THE HOLD-ON INPUT IS IDEAL FOR OVERRIDING AN OCCUPANCY SENSOR TO FORCE LIGHTING ON DURING NORMAL BUSINESS HOURS IN RETAIL AND COMMERCIAL FACILITIES. AFTER HOURS, A TIME CLOCK SIGNALS THE BZ-250 TO CANCEL THE HOLD-ON MODE, ALLOWING THE SENSOR TO RESUME CONTROL. THE HOLD-OFF INPUT CAN BE USED FOR LOAD SHEDDING OR SECURITY SYSTEMS – BY WATTSTOPPER

Description

This is the lighting & plug load flex control power pack. The BZ-250 power pack switches lighting or plug loads On and Off in response to low voltage control inputs, and provides up to 225mA at 24VDC to power Wattstopper occupancy sensors. It enables Manual-On sequences of operation, as well as HoldOn, Hold-Off and load shed applications when used with lighting control panels or building automation systems. This device is constructed with environmentally friendly materials and is RoHS-compliant.

The BZ-250 consists of a high-efficiency switching power supply and a high-current relay. It turns the connected load Off automatically based on occupancy sensor input, and On either automatically based on occupancy, or manually in response to a low-voltage momentary switch. The installer can select Auto-On or Manual-On operation via an actuator switch on the power pack. The BZ-250 also accepts low-voltage Hold-On and Hold-Off inputs for broader applications. The BZ-250 relay can be set to open, close or maintain state prior to loss of power, so that lighting is in the preferred state (On, Off or last state) when power is restored.
