Programmable AC Power Supply
ESA Series Programmable AC Power Supply
Modular high-power programmable AC power supply with configurable power, voltage, current and frequency ranges.

The ESA Series high-power AC power supply features a modular design with configurable output power, voltage, current and frequency ranges, for new energy testing, power electronics R&D and motor drive systems. The -R option provides four-quadrant operation with bidirectional energy flow, and -LD adds regenerative electronic load functions.
