Air Cooled VFD Cabinet, AS700

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. A good heat dissipation is kept by using air cooling method, efficiently lowering energy consumption.


Features

  • Special air duct design
    The air duct is specially designed with higher power density, which can be easily installed.
  • High operating temperature, longer device life
    It is able to operate at 42℃ without derating, and it can still run at the maximum ambient temperature of 55℃ with derating.
  • Flexible and customized design
    Customized design (installation mode, protection grade, cabinet color, control loop function, etc.) can be realized according to different customer needs.
  • Integrating a variety of software functions required by HVAC industry
    Segmented acceleration and deceleration, overcurrent frequency reduction, frequency hopping function, hardware shutdown (some power segments are optional).
  • Adapting to high temperature and humidity environment in HVAC industry
    1) 3C3 circuit board coating
    2) IP44 protection grade (outdoor use requirements can be customized)
    3) 250-hour salt spray test
