The Battery Backup BBU option for the Bray Series 70 24VAC actuators provides a convenient and cost effective solution to provide return of the valve or damper to a user-selectable position upon loss of supply power. The BBU is available for both On/Off and modulating actuators. The advanced circuitry of the BBU continuously monitors battery strength and provides a visual indication (LED) and remote indication (via dry contact). The BBU is housed in sturdy die cast aluminum NEMA 4x (IP 65) enclosure.

Battery Backup Operation: In the normal mode of operation with power supplied to the actuator, the batteries maintain a charge and are in an offline mode. The power applied to the motor is from the power supply, not the batteries. When a power loss occurs, the BBU pauses for 5 seconds and then reads the “Open/Close” fail position switch setting. The BBU circuitry applies the stored power in the batteries to move the valve or damper to the full open or full closed position designated by the user. The actuator remains in this position until external power is restored to the unit.  For two position (on/off units), and modulating units, the BBU board automatically detects when the actuator has reached the desired position and then disconnects the battery power from the motor.
