AS170 series variable frequency drive is a 400V (380V-460V) universal motor integrated VFD, which is suitable for three-phase AC asynchronous motors with capacity of 1.5-15kW. Through the redesign of the overall appearance and structure, the perfect match between motor and VFD is achieved. With the protection grade of IP55, this integrated VFD can be used in humid and dusty environments, and it simplifies the installation and commissioning, providing a new driving solution.
The water pump fitted with this integrated VFD is commonly used in secondary water supply, constant pressure water supply, irrigation, municipal water supply, sewage discharge, etc.

STEP's air cooled VFD was particularly developed for HVAC industry. It adopts mature control technology, the ratio between voltage/frequency is automatically adjusted according to the motor load, thus greatly improving the efficiency of the system.
AS720 series liquid cooled VFD adopts STEP's mature platform of VFDs. The radiator of the general VFD is replaced with a cold plate cooled by refrigerant, which greatly reduces the size of the VFD while saving the cost. The power of cold plate VFD covers a range from110kW to 710kW.
