Automatic controller, HY-RPCF12-49120, for reactive power compensation capacitors by ELMARK. Input voltage 240~400VAC for controlling capacitor systems with up to 12 outputs.
Reactive power compensation controllers help stabilize large voltage differences. They are intended to assist the operation of capacitor systems as well as to prevent overloading. In this way, they extend the life of the capacitors. The controller analyzes the current and voltage of the system and stores their maximum values and calculates the distortion of the current and voltage values. If the distortion is greater than the set values, it turns off the capacitor battery and gives an notification.
