PAS Series product is developed for renewable energy related applications. It can simulate the various grid conditions and related test standards. Especially the voltage or frequency transient simulation test feature, it is suitable for production, quality verification, research and development.It also builds in with Low Voltage Ride Through Test (LVRT) test function, step mode and gradual mode programmable capability. PFV Series is a new generation of programmable AC power supply, with four quadrant energy feedback function. This unit not only provides power to the EUT, but also sinks the power back to the grid system which is useful for grid tie devices testing applications. The maximum output power for PAS series is up to 2000kVA, and the PFV series is up to 200kVA. The output voltage range is 0~300VL-N and the standard output frequency is 45~65Hz continuously adjustable (optional 40~70Hz).

PAS series is a four-quadrant AC power source which is capable to be a power source or sink the power from the EUT back to the grid system with 90% efficiency. It is suitable for PV Inverter test, EV charger test or other grid tie devices test. Build in with Low Voltage Ride Through (LVRT) test graph and it is very suitable for IEEE-1547 or BDEW related standards compliance test.
PAS built in HVRT/LVRT can simulate the situation when the abnormality is ruled out from on the main AC grid. Simulations such as voltage drop, voltage restore or rising time and remaining time can all be programmed.
Independent setting for three phase high/low voltage ride through to simulate voltage drop and surge.
The PAS series is a grid simulator particularly designed and developed for renewable energy related applications. It has been widely applied for the testing applications of smart inverters, battery charging/discharging, Power Conditioning System (PCS) and Vehicle-to-grid (V2G). The PAS series not only provides power to the EUT, but also sinks the power back to the grid system, which is suitable for grid testing application.
PAS series’ harmonics waveform synthesis function can allow user to program multiplex distorted harmonic waveform of up to 25 steps. It can simply set up voltage and adjust start phase of each step base on fundamental frequency 50Hz or 60Hz.
PAS / PFV series have multiple programmable functions to precisely and effectively simulate various power line disturbances such as voltage or frequency ramp up or ramp down, transient and step changes.
