SoftStartRV provides an effective solution in the reduction of start-up current, typically up to 70%, but still provides full startup torque for compressors and motors. The 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. Plus, 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 systems. It is the best soft start rv a/c kit.
SoftStartRV is an embedded design air-conditioner soft start controller for single phase soft start for air-conditioner power systems. It regulates the start-up voltage of the compressor/motor intelligently to effectively reduce the inrush and surge current while starting-up, thus consuming much less power from on-site AC power supply system – yet it still provides full startup torque for compressors and motors.
SoftStartRV effectively limits the inrush current and so improves the stability of the power supply and reduces transient voltage drops that may affect or break down other loads. This eliminates the need for excessive power supply which results in reduced equipment costs, investment in power supply capacity, charge meter, circuit breaker, and power wireline capacity, and it extends the service life of the motor or compressor.
Not only does the SoftStartRV ease strain on the power source, but it’s also less stressful for the Compressor itself since it starts more gently. Additionally, it provides valuable protection by shutting down the compressor if the power source or the connection to the compressor is briefly interrupted, then it re-attempts a soft start after a three-minute delay.
SoftStartRV is a compact size, lightweight cost-effective soft start controller with fireproof housing and sealed by resin making it capable of resisting extreme weather and survive in harsh environments (A/C air-conditioner outdoor rooftop unit), this makes SoftStartRV a cost-effective rv air conditioner soft start kit solution with high reliability and stability.
