ZHIMING  brand of ZMCF series automatic reactive power compensation capacitor controller is designed for use in low-voltage power distribution systems. It automatically regulates capacitor banks to maintain the power factor at a preset level, thereby improving transformer efficiency, reducing line losses, and enhancing voltage stability and power quality.

Functional Features

• Calculates compensation capacity based on fundamental reactive power to prevent switching oscillation.
• Accurately displays system power factor, even in the presence of harmonics.
• High precision measurement with a wide display range for power factor.
• Real-time monitoring of total power factor (PF).
• Real-time display of voltage and current total harmonic distortion (THD).
• User-friendly human-machine interface for easy operation.
• Multiple control parameters are presented via a digital display for intuitive configuration.
• Dual operation modes: Automatic and Manual.
• Built-in over-voltage and under-voltage protection.
