Product Overview
The JKGF-8 series reactive power automatic compensation controller is an intelligent device designed for low-voltage power distribution systems, specializing in optimizing reactive power compensation. It employs dual-parameter composite control technology that integrates reactive power and power factor measurement to ensure stable capacitor switching under varying load conditions. With robust anti-interference capabilities and harmonic adaptability, it is compatible with various capacitor compensation cabinets and panels. 21324
Key Features
This controller supports cyclic switching with configurable 4/6/8/10 output channels, offering both phase-voltage and line-voltage sampling modes. Its standout feature is the automatic adjustment of control intervals based on reactive current during light loads, effectively preventing excessive capacitor switching cycles. Real-time monitoring covers power factor, voltage, and current, while protective functions include adjustable over-voltage protection (230-460V range) and under-current blocking (6%-20% settable). Dynamic output models enable direct control of composite switches for rapid response. 91528
Technical Specifications
Operating voltage ranges from 220V to 380V (±20% tolerance), with an ambient temperature range of -25°C to +70°C and altitude limit of 2500 meters. The 5A current sampling input and relay output (AC220V 6A resistive) ensure reliable performance. Delay time is adjustable between 5-90 seconds, and modular design allows panel-mounting (112×112mm cutout) or wall-mounting installation for flexible integration. 15289
Applications
Ideal for power factor correction in industrial plants, commercial buildings, and substations, this controller reduces line losses and enhances voltage stability by automating capacitor bank operations. Typical applications include textile machinery, plastic injection molding equipment, rolling mills, and other sites with intensive inductive loads, as well as industries like metallurgy and mining where harmonic disturbances exist. 32428
