The converters are designed to control the asynchronous electric motor of the compressor unit of an electric vehicle with a three-phase voltage of 3x220V with a frequency of 50 Hz. The product complies with modern trends in world technology and is based on a 32-bit microprocessor specialized for working with three-phase motors and a power transistor IGBT module.

The converters have two versions - PSK4A.1E and PSK4A.1EM, which provide the operation of an asynchronous motor with and without a sine filter, respectively.

The control panel allows you to change and save the parameters of the transducers in non-volatile memory, as well as view the accumulated messages about emergency situations.

The converters have all control and diagnostic functions that allow protecting both the converter and the asynchronous machine from damage. They are resistant to short circuits in the load circuit, motor jamming, power supply overvoltage, wire breakage that feeds one of the motor phases, converter and motor overheating.
