Regenerative Function

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.

Low Voltage Ride Through (LVRT)

Built-in Low Voltage Ride Through (LVRT) mode can simulate the grid in abnormal conditions. The settings include rated voltage, frequency, drop voltage, recovery voltage, rise time and drop time to simulate various grid conditions.

A Variety of Built-in Programmable Features

PAS/PFV series has a number of programmable features that can effectively and accurately simulate a variety of power abnormal conditions or disturbance. Through the built-in step and gradual mode, users can simulate voltage and frequency single-step or continuously changes, such as voltage and frequency ramp up/ ramp down, instantaneous changes, and so on. Phase angle and three phase independent adjustment function can be used for simulating three phase imbalance and further test the reliability of the EUT. With low voltage ride through and regenerative function, PAS series is suitable for PV Inverter, Bi-directional EV charger, Energy Storage System as an all purpose grid system simulator.

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.
