Description：
The WPAP-series high-power variable-frequency power supplies feature a touch LCD screen, which can display multiple data to be monitored, such as voltage, current, active power, reactive power, etc. The touch screen operation makes the parameter settings intuitive and the operation simple. The WPAP-series programmable power supplies can simulate abnormal phenomena of the mains power such as sudden increase, sudden decrease and fluctuation through instantaneous voltage changes; they also have perfect protection functions: over-power, over-current, over-voltage, short circuit, over-temperature, etc. The RS485/232 communication interface they are equipped with also makes remote operation and automation more convenient.
The programmable and strong load-carrying capacity feature is often used in industries such as grid compensation contactors, aging tests, whole machine testing of photovoltaic inverters, and household appliances.
