Product Description

Low Voltage Reactive Power Compensation Controller

The JKW type low-voltage reactive power compensation controller is the latest high-tech product successfully developed by our company. It adopts a series of leading domestic technologies and the latest electronic components, and is currently the most cost-effective product for reactive power compensation controllers in China. It can not only be matched with reactive power compensation devices to compensate for reactive power losses in the power grid, improve power factor, reduce line losses, thereby improving the load capacity and power supply quality of the power grid; It can also monitor the voltage, current, reactive power, power factor, harmonics and other operational data of the power grid in real time, and can complete real-time monitoring and data analysis of the entire low-voltage distribution line system.

Product Introduction

Fully digital design, foolproof parameter setting.

Real time display of power factor, voltage, current, reactive power, and capacitor switching status.

Capacitor control supports two different compensation methods: power cycling switching or reactive power optimization switching, which can be set through menu operations.

It has two working modes: manual compensation and automatic compensation.

The sampled physical quantity is power factor or reactive power.

Scope of application: This product is suitable for 380V/220V low-voltage distribution networks and can be installed and used indoors or outdoors.

Environmental temperature: -25 ℃~+70 ℃; Altitude: ≤ 2000 meters;

Relative humidity: 20% to 95% at 40 ℃;

Workplace: Work in a place without obvious conductive dust and flammable or explosive media.

Installation location: No severe vibration, no rain or snow erosion. The installation inclination should not exceed 5%.

Display function: LED digital tube display for data display

Measurement voltage: 100V~500V

Measurement current: 0-4500A (primary) Sensitivity: 60mA (secondary)
