Power factor controller RVT-DL

Smart control for dynamic reactive power compensation

RVT-DL is specifically designed to control the operation of static (thyristor) switches in an automatic capacitor bank. Loaded with a wide range of monitoring and control feature, it is a user-friendly and efficient device that can be commissioned manually or automatically.

RVT-DL can perform both single phase as well as three-phase measurements. Based on the measured values of currents and voltages, it monitors network power factor continuously and switches on or off different capacitor stages in case of deviation in it, as per the set power factor value, in an optimized manner. The high-quality LCD display of RVT-DL shows all critical parameters of network and equipment, like currents, voltages, active and reactive powers, power factor and harmonic distortion values.

For physical and digital security, RVT-DL is equipped with features like programmable overtemperature trip setting, fan control and password protection. With a wide range of connectivity options, the controller can be integrated to any PLC, energy management or building management system.
