Standard lineup of diverse systems up to three-phase 90kVA.
The ES series is a programmable AC power supply that can flexibly construct various power systems ranging from single-phase 2kVA to three-phase 90kVA*. With our long-standing linear amplifier-based power control (linear power control), we provide fast and high-quality power. It also supports the fast response and harmonic superposition required for EMC testing, as well as the reverse flow necessary for power conditioner (PCS) grid interconnection testing, allowing for tests that meet the conditions required for standard and certification tests.
