CPH smart harmonic suppression compensation module

The CPH series smart harmonic suppression compensation module is based on low-voltage pure dry-type capacitors. It adopts the latest achievements in microcontroller technology, micro-sensors, micro-network technology and electrical appliance manufacturing technology. It integrates zero-point switching, protection, measurement, and online functions in one. It is a major breakthrough in the existing low-voltage reactive power compensation filtering technology. It is mainly used in reactive power compensation in very severe harmonics to ensure reliable operation and absorb and eliminate harmonics to a certain extent.

Features

Functions of CPH smart harmonic suppression compensation module

Smart harmonic suppression compensation module
Sync switch: >1 million times trouble-free switching, strong withstand voltage, current shock and anti-harmonic ability.

Record Function

Real-time flexible monitoring : Real time monitoring and standard Modbus RTU communication.

Perfect protection function: With current quick-break, overload, phase loss, three-phase unbalance protection, and over-voltage, under-voltage, loss of voltage, over-temperature, harmonic overrun and other protection types
Fault self-diagnosis: Once the slave self-diagnoses the fault, it will automatically exit immediately without affecting the normal operation of the system; if the master fails to exit, the slave will rebuild the online network.

Online function: <32 units online connection
Flexible compensation method: Optional centralized and decentralized control
