TL-ASSU220P5is an embedded design compressor/motor soft start controller, suitable for rated current less than 18 ampere all type single phase air conditioner（4HP-5HP）. 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. TL-ASSU220P5 effective limits the inrush current and so improves stability of the power supply and reduces transient voltage drops that may cause brown-out effect 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.
TL-ASSU220P5is a compact size, light weight cost effective soft start controller with fire resistant plastic housing and sealed by epoxy resin make it capable to resist and survive in harsh environment (air-conditioner outdoor unit), this makes TL-ASSU220P5 a cost effective solution with high reliability and stability of:
 Eliminate over dimension of generator and AC power supply system for compressor start-up need.
 Reduces strain on the power source.
 Reduces brown-out effects at compressor start up.
 Enable an inverter to power air conditioner.
 Inexpensive and cost effective.
 Small, lightweight and durable.
