RPCF series reactive power automatic compensation controllers

Product catalog summary

General Overview
The RPCF series reactive power automatic compensation controllers are designed to automatically adjust low voltage distribution system capacitor compensating devices. This adjustment aims to achieve a predetermined power factor, enhance the efficiency of power transformers, reduce line losses, and improve power supply voltage. The controllers operate at a rated working voltage of AC 380V or AC 220V, with a current range of AC 0~5A and a frequency range of 45Hz~65Hz.

Ordering Notes
Users must specify the number of circuits, rated voltage, and type of switch (contactor or combination switch) when ordering. For mixed compensation installations, an RPCF3-16 type reactive power auto-compensation controller is recommended.

Types and Meanings
The controllers are categorized by output type (static or dynamic), total output steps (ranging from 4 to 16), and communication functionality. The RPC designation indicates a reactive power compensation controller.

Normal Working and Installation Conditions
The controllers are suitable for ambient temperatures between -25℃ and +55℃, relative humidity levels of 40% ≤20% and 20% ≤90%, and altitudes up to 2500m. They should be installed in environments free from noxious gases, vapors, conductive or explosive dust, and violent mechanical vibrations.

Main Parameters and Features
The controllers feature high measuring accuracy for power factor, real-time display of total and fundamental wave power factors, and voltage and current distortion rates. They offer 12 output codes for user selection, a maximum of 16 output steps, and a user-friendly interface. Additional features include auto and manual running modes, over-voltage and under-voltage protection, voltage harmonic wave protection, and data retention during power outages. The input impedance for lower current signals is ≤ 0.01Ω.
