PRC-8F


PRC-8F power factor controller is a new type of intelligent power factor controller reactive compensation control, protection of the four quadrant electric parameter measurement, fault and alarm, data acquisition, communication, power grid parameter analysis and other functions in one, suitable for middle and low pressure 50/60Hz system network, the switch to control the speed of up to 25 times / sec, and can be used for connection control mechanical type contactor or thyristor switching controller (230VAC control).

Function characteristics
Real-time detection of distribution system power factor and reactive current, automatic switching capacitor group, to achieve power factor set; can also pass through the set to achieve manual switching capacitor group
The fault alarm is perfect (over-voltage under voltage alarm, harmonic voltage limit alarm, over temperature alarm and protection function, etc.) to ensure that the reactive power compensation and filtering equipment complete and reliable operation
Electrical parameter measuring function rich, help customers to master the real-time distribution system and operation condition of reactive power compensation filter device
Instantaneous power factor compensation and average power factor compensation
Metal shell, EMC protection better
Measurement parameter maximum recording, easy to see the change of system parameters
Dual expansion, set free the master-slave, and from the machine without the need of voltage and current measurement system, is easy to control the expansion of compensation capacity
