Our "Test Load Device for UPS, Inverters, DC Power Supplies, and Power Conditioners" allows for arbitrary settings from 0 to rated current in the AC100V/200V range. The load can be incrementally built up in 15 steps up to the maximum rated current, with fine adjustments possible at each step. Additionally, it can perform load tests in three modes with a single unit. 【Features】 ■ Capable of switching between single-phase (1Ph, 2W) AC100V/AC200V for testing ■ Power factor adjustment range is standard from 0.7 to 1 ■ Can be used for load sudden change tests with a load resistance disconnection switch ■ Fine adjustments possible for each step ■ Compatible with external reactor connections, etc. *For more details, please download the PDF or feel free to contact us.
