The RPCF-6 controller is a device specifically designed for the automatic regulation of capacitor compensation devices in low-voltage power distribution systems. It can effectively enhance the utilization power of power transformers, reduce line losses, and improve the quality of power supply voltage. The controller uses advanced technology to calculate the switching capacitor capacity based on fundamental reactive power, avoiding any form of switching oscillation and accurately displaying the power factor of the power grid in the presence of harmonics. It features high accuracy in power factor measurement, wide display range, and the ability to display total power factor (PF) and fundamental power factor (DPF) in real-time, as well as voltage and current distortion rates. In addition, the RPCF-6 controller offers multiple functions, including 12 encoding output options for users, up to 16 output channels, user-friendly human-machine interface, fully digital adjustable control parameters, automatic and manual operation modes, overvoltage and undervoltage protection, voltage harmonic over-limit protection, and data retention during power loss. The normal operating conditions include an ambient temperature range of -25℃ to +55℃, relative humidity not exceeding 50% at 40℃ and 90% at 20℃, and an altitude of no more than 2500 meters.
