ProCap™ Electronic Capacitor Controls

Maysteel Electronic Capacitor Controls are designed to automatically switch pole-mount and pad-mount capacitor banks. Depending on the series and model, Maysteel Capacitor Controls can monitor and control capacitor banks based on combinations of time of day, ambient air temperature, system voltage and system VARs. Programming can be accomplished through the simple front panel controls and LCD digital display, or via a portable computer through the supplied RS-232 interface.

All of our capacitor controls feature Adaptive Trip. The control anticipates voltage changes caused by the opening and closing of the capacitor bank by measuring the line voltage before and after each switching operation. The stored information is used to prevent or defer unnecessary capacitor bank switching operations, extending the life of the switches and the capacitors.

The following models are currently available:

ProCap™ 140T/150T Voltage/Temperature Controls
1300 Time Control with Voltage Override
1600 Time with Voltage and Temperature Override
2000 VAR Control with Voltage Override
