Intelligent Capacitor
Intelligent CapacitorIntroduction:：RXZNG Series and RXZNF Series intelligent combined low-voltage power capacitor is a new generation 0.4KV low-voltage reactive-load compensation equipment,Website:, which reduces energy consumption, improves power factor and improves electric energy quality. It mainly consists of a measurement control display module, combination switch unit, breaker protection unit and a 0.4KV low-voltage power capacitor with a temperature sensor. Integrated structure is adopted by the device to replace low-voltage complete equipment composed of complicated mode of wiring and dispersed components such as general intelligent controller, fuse, combination switch or alternating current contactor, thermal relay, low-voltage power capacitor and indicator lamp, thus to ensure simple wiring, easy installation and commission, and convenient maintenance. Combined low-voltage power capacitor can be used as a unit set and also on-line applied with multiple units through networking. Our reactive-load compensation measuring and control equipment can be selected to match in case of high compensation capacity and the need of display the parameters such as voltage, current, power factor, reactive and active power, compensating current and etc.Environmental ConditionsAmbient temperature: -25℃～+60℃ Relative humidity: 30%～85%RH Altitude: ≤2000mPower Supply ConditionsRated voltage: 220V～450V Voltage deviation: ±5% Harmonic voltage: Sine wave, with total distortion rate no more than 5% Working frequency:50HZ Harmonic current: The allowable harmonic current at the point of common coupling shall not exceed the value required in the standard BG/T14549-1993.
