RENLE Low Voltage Inverter Governor RNB3000 Series Automatic energy saving

Product introduction: RNB3000 series inverter is used to control the speed of three-phase AC motor inverter, the product adopts modern microprocessor technology and SVPWM control theory technology, and adopts insulated gate bipolar crystal Youku tube IGBT with modern technical level as the power output device. Therefore, it has high operating reliability, and the adjustable carrier frequency greatly reduces the noise of motor operation. The perfect protection function of this product provides good protection for the inverter and the motor.

RENLE / Reynolds RNB3000 series

Scope of application:

It is suitable for the system where the operating condition of fans, air compressors and pumps deviates from the high-efficiency area;

It is suitable for systems with large changes in pressure and flow rate and long running time;

It is suitable for systems that regulate flow using wind shields, valve interception and bypass diversion;

Fans of medium and low flow change types, air compressors, pump loads, and full flow gap types.
