ABB power factor controller product description
RVT no-power automatic compensation controller, used for automatic adjustment of capacitor compensation device of low-voltage distribution system (hereinafter referred to as RVT), using power factor to reach the user's predetermined state, improving the utilization efficiency of power transformer, reducing line loss, improving the voltage quality of power supply . The maximum power consumption of the power factor controller RVT is 15VA, the full graphic display pixel is 64*132, and the RVT-12 can be up to 12 programmable outputs mounted on a vertical plane.
Application range
Calculating the capacitance of the switching capacitor with the fundamental reactive power can avoid any form of switching oscillation and can correctly display the grid power factor in the presence of harmonics. ● High power factor measurement accuracy and wide display range. ● Real-time display of total power factor (PF) and fundamental power factor (DPF) ● Real-time display of voltage distortion rate and current distortion rate; ● 12 kinds of code output modes for users to choose; ● Up to 16 outputs; ● Human-machine interface friendly Easy to operate; ● Various control parameters are all digitally adjustable and easy to use; ● It has two modes of operation: automatic operation and manual operation. ● With over voltage and under voltage protection function; ● With voltage harmonic over standard protection function; ● With power failure Protection function data is not lost; ● Current signal input impedance is low ≤0.01Ω
