VCR Series Voltage Control Relays
TRUE RMS MEASUREMENT • PRECISE THRESHOLD CONTROL • COMPACT DESIGN

VCR series voltage control relays prevent sensitive electronic equipment and industrial motors from damage caused by unstable grid voltage fluctuations. Using the True RMS method, they analyze grid voltage in real time and isolate the system within seconds when set thresholds are exceeded. Both a protection device and diagnostic tool for modern automation panels.
Precise Voltage Analysis
Monitors lower and upper voltage limits with 1% accuracy; instantly detects sudden surges and voltage sags.
Adjustable Hysteresis and Timing
Ensures safe switching with user-defined fault return difference (hysteresis) and trip delay to prevent instability.
Compact Form Factor
Maximizes space efficiency in densely populated panels with its 30mm wide slim design.
Visual Diagnostics
Front panel status LEDs allow personnel to instantly distinguish between "Over Voltage" and "Under Voltage" faults.
