  Description of product

  This product is suitable for the inter-turn isoelectric performance test of various types of motor stators under vacuum negative voltage up to -99kPa, widely used in air conditioners, refrigerator compressor stators, automobile motor stators, brushless stators and other industries.


  1.Vacuum: free setting of vacuum between 0~-99kPa (0~-742.5Torr).

  2. High efficiency: Custom double-station serial/parallel test system. The four tests of turn-to-turn and withstand voltage can be completed within 5.9 seconds, up to 10,000 pieces/day.

  3. High performance: voltage regulation, insulation, turn-to-turn and other voltage adjustments using closed-loop voltage feedback adjustment system to accurately control the voltage regulation and rising process, stable voltage output.

  4. Intelligent: intelligent self-check, remote diagnosis and online upgrade, quick location of problems and eliminating.

  5. Multi ports: USB, RS232, LAN and other ports, PLC simulation, TCP/IP network protocol, etc., to facilitate data interaction and instrument control.
