BI-TORQ provides battery back-up systems for 115VAC and 230VAC electric actuators for applications that require a safety system in case of catastrophic power loss. The battery back-up is enclosed in a NEMA 4 enclosure and can be panel mounted or mounted on to the conduit of the actuator.
The square sine wave power supply is routed to the operator selected designated fail position which drives the actuator open or close as selected. Upon return of utility power the electric fail-safe device automatically reverts to standby status allowing the control of the actuator to transfer back to the controller. The actuator will travel to the position transmitted by the controller at the time the utility power resumes.
