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).

Regenerative Function

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.

HVRT and LVRT Function

HVRT and LVRT Function

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.

Three Phase Independent Output Voltage Setting

Three Phase Independent Output Voltage Setting

Independent setting for three phase high/low voltage ride through to simulate voltage drop and surge.

Ideal For Grid Simulation Applications

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.

Ideal For Grid Simulation Applications

Harmonics Waveform Synthesis Function (Opt.)

Harmonics Waveform Synthesis Function (Opt.)

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.

GRADUAL and STEP Function

GRADUAL and STEP Function

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.


  • PAS has built-in low voltage ride through (LVRT) mode, which can be easily used for simulating the voltage drop test according to different test standards.
  • PAS/PFV equip with energy feedback feature that feeds energy back into the grid system for saving energy and sinking the power from grid tie devices.
  • PAS series is suitable for standard verification. For example: UL1741,IEEE 1547, BDEW, and CEI0-16 etc.
  • Three phase independent voltage adjustment is suitable for three phase unbalance testing or multiple single phase test units. It also equips with phase angle adjustment.
  • Standard RS-232,RS-485 communication interface, optional GPIB, Ethernet and USB.
  • With 7 inch LCD touch screen display, it can display output voltage, current, frequency, active/apparent power, power factor, test information at the same time.
  • More protection mechanism, detect output undervoltage overvoltage, overcurrent, over load , input undervoltage/overvoltage, over temperature... etc 20 fault conditions and record 255 operation and alarm information for troubleshooting and analysis.
  • Step or gradual mode programmable memories can be used for simulate abnormal power condition and run in automatically sequences,which allows you to setup different voltage and frequency in each steps for your power simulation requirements.
