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 and is factory mounted and factory wired to the Bray Series 70 24VAC actuator.

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.

The Series 70 industrial actuators have become the industry standard in the Commercial HVAC industry due to it’s compact, reliable design that mounts directly to Bray’s industry leading butterfly and industrial ball valves without the need for brackets and linkages. Available in torque outputs from 600 to 18,000 lb.-in. (68 to 2033 NM), 24V and 120VAC, On/Off and Modulating units all in NEMA 4x and IP65 rated housings. These actuators are ideal for use on valves for Chillers, Cooling Towers, Boilers, Heat Exchangers and other outdoor applications. Furthermore, its advanced electronics assure reliable compatibility with virtually any analog control signal used in today’s building automation and temperature control system.

The Series 70 Servo NXT provides precise modulating control of valve position:
- Single Finger Technology (SFT) menu driven, pushbutton, programming with LED confirmation of all settings.
- Optical isolation of all inputs/outputs.
- Input Control - 4-20 mA or 0-10 VDC or 0-5 VDC or 2-10 VD.
- Position Feedback - 4-20 mA or 0-10 VDC or 0-5 VDC.
- Auto Calibrating.
- Fail Position.
- Speed Control.
- Manual Mode.
- On board signal generator to simplify field set up.
- Fault display simplifies troubleshooting.
- Stall detection- Eliminates mechanical damage in case of obstruction or bad switch settings.
- Provides interoperability with all controllers.
- Earth ground tolerant.
- Allows for parallel operation.
