The AZX Series (Regenerative AC / DC Power Source) is a family of high power, single, split and three phase, AC, DC and AC+DC output capable Power Sources with full energy recovery to the AC mains when sinking power from the equipment under test. Available models range from 30 kVA to 440 kVA. Using a modern color touch screen based user interface for ease of use, the AZX Series is cost effective and fully programmable for both basic frequency conversion and advanced AC power line or DC power disturbance test applications requiring up to 1000 Hz fundamental frequency.

The energy recovery capability allows both sourcing and sinking of current and power up to 100% of rated power. Adding the Load Option (Option L) adds full electronic regenerative AC & DC Load programming capability to the AZX.
