Accurate control performance

1: Optimized vector control performance, fast response and stably torque 

    output at low frequency;

2: More than 30 failure protection functions build-in, ensure the system 

    works stably and safety.

First-class components build-in

1: Select first-class components strictly, ensure the products have good 

    quality;

2: Never cheat on the    material, sufficient size of component selected.

Better environmental adaptability

1: Full automatic PCBA coating, high quality conformal coating material 

   selected. Better performance of  waterproof, dustproof and anti-corrosion.

2, Independent air duct design, better heatsink performance.

3. Sufficient radiator and cooling fan design, low temperature rise on VFD 

    itself.

Better EMC performance

Optimized hardware and software design, better EMC and 

anti-interferences performance.
