Description
The easy-Drive RPU-100 is a reserve power unit designed to provide backup power to the easy-Drive actuator upon
loss of incoming power. The RPU-100 provides enough power to the actuator to allow the actuator to drive the valve
to the pre-defined loss of power or loss of signal position. The RPU-100 can be ordered with a new easy-Drive assembly
or be retrofit into existing easy-Drive units that have the Gen2 control board.
