    Air Conditioner Bypass Soft Starter Single Phase 220VAC 7P Reducing Start Current

    Air-Conditioner Soft Starter Single-Phase 220VAC 7P Reducing Start Current


    The soft start controller NK-ASSU220P7 provides an effective solution in reduction of start-up current, typically up to 70%, but still provides full startup torque for compressors and motors. Across the line starting of air-conditioner compressor or induction motors is accompanied by inrush currents up to 7-8 times higher than running current, and starting torque up to 3 times higher than running torque.


    The increased unnecessary torque results in sudden mechanical stress on the machine which leads to increased wear and higher service costs and reduced service life. Moreover, the high inrush current and current peaks may stress the power supply system to increased mains and generator loads which may lead to voltage dips results in breaking down of other valuable equipment or system function.


    NK-ASSU220P7 is an embedded design air-conditioner (for single phase power system) soft start controller. It regulates the start-up voltage of the compressor/motor intelligently to effectively reduce the inrush and surge current while starting-up, thus consume much less power from the public utility network or on-site AC power supply system but still provides full startup torque for compressors and motors.


    NK-ASSU220P7 effective limits the inrush current and so improves stability of the power supply and reduces transient voltage drops that may affect or break down other loads. This will eliminate the need of over dimension of the power supply system which results in reduce capital expenditure investment in power supply capacity, charge meter, circuit breaker and power wire line capacity etc..and extend the service life of the motor or compressor effectively.


    NK-ASSU220P7 is a compact size, light weight cost effective soft start controller with fire proofed housing and sealed by resin make it capable to resist extreme weather and survive in harsh environment (air-conditioner outdoor unit), this makes NK-ASSU220P7 a cost effective solution with high reliability and stability.
