The PAS series grid simulator is specifically developed for renewable energy type tests. It is able to simulate the grid condition required by UUT and regulations, such as voltage abnormality test, frequency abnormality test, or low voltage ride through. It can be used in R&D, production, or quality check stage of PV inverter, wind turbine converter, electrical vehicle, smart gird and etc.


With power level up to 2000kVA, the PAS series provides output voltage range of 0~300V and output frequency of 45~65Hz. Users can select communication interfaces of standard RS-485 and RS-232 and optional GPIB, LAN, and USB. The PAS series also have programming sequence functions of STEP and GRADUAL modes, three phase independent control, phase angle control, disturbance function and regenerative function. The built-in low voltage ride through (LVRT) function is for specially designed for renewable energy testing purpose.
