The machine before delivery on the high temperature aging, vibration test.

Perfect and reliable system protection function

Protection of no voltage, less voltage and over voltage.

Protection of overheating and starting time too long.

Protection of Input phase lost, output phase lost and 3phase unbalance.

Protection of starting over current, running overload, and load short circuit protection.

Maintenance function

Fault self-diagnosis(short circuit, over voltage, less voltage, one phase grounded, motor overload, one phase lost,

motor blocked, and intelligent software can inspect drag system working state).

Combination of modular design, according to the fault display content, quick troubleshooting..
