Pro Power Essential Constant Current Regulators

The Pro Power regulator uses a ferroresonant core designed to withstand overvoltage and surges and runs more efficiently.  These regulators are air cooled and designed for long life indoor service.

The Pro Power design also creates a cleaner sine wave that improves communication on the power lines and helps to prolong the life of incandescent lamps on the circuit.

Offering full L-829 capabilities, the Pro Power displays all of the CCR inputs and makes monitoring the system easy.
