Product details
I. Product introduction
RVC-Z reactive power compensation controller has 3-phase voltage/current sampling function and allows any combination compensation of Y+△. The other basic technical performances are same as RVC. It can output DC 12V to control contactless switch or connect 220V/380V AC contactor to switch capacitor for reactive compensation. The controller is designed with reactive power/current and comprehensive sampling and the most advanced programmable switching mode (1:1:1:1, 1:2:2:3, 1:2:3:4…………), and allows the automatic selection of split phase or 3-phase preference strategy according to the load condition. It offers the best reactive compensation effect in various conditions and environments. RVC series controllers have powerful function and high interference resistance, can operate normally in network environments with a high THD, and have alarm functions such as high harmonic alarm, RS 232/485 communication interface, MOTBUS communication protocol output.
