Electric Options – Series 94 Protek Battery Pack

The Quarter master Protek Failsafe Electric Actuator features a rechargeable battery pack that is capable of 25 cycles under full load conditions, a built-in trickle charger, a low battery indicator, and an auxiliary limit switch that is calibrated with the fail position. The battery pack is installed inside of the actuator housing, so a separate enclosure to house the battery in not required.

When power is received from the primary power source, it is directed to the actuator motor and switches for normal cycling of the actuator. When the primary power source is interrupted, the battery pack is then connected to the motor and switches, and powers the actuator to the failsafe position. In this failsafe position, the auxiliary limit switch is tripped, and can be wired to an alarm. Once the primary power source is restored, the battery pack is disconnected and normal operation resumes.

Ideal Applications Include: 

Chemical Processing, Water & Wastewater, Landfills, Irrigation, Food Processing, Mining
