The NF Corporation ES2000U is part of the P-STATION/ES Series Programmable AC/DC Power Source products that can simulate power supply environments. Performance, functionality, compact and lightweight profiles, and ease of use are emphasized in this series. Single-phase and three-phase systems can be built by combining P-STATION/ES-Series products.

A single-phase system is built with the ES 2000S single-phase master as its base and ES2000B boosters added to obtain output power ranging from 2kVA to 20kVA.

A three-phase system can be built with one ES2000U three-phase master and 2 ES2000P three-phase slaves as its base. By adding ES2000B boosters to each phase, the system can have output power ranging from 6kVA to a maximum of 60kVA.

Because the output voltage has low waveform distortion and features a stable voltage level and frequency, it is suitable for the power supplied in performance testing of electronic devices and EMC measurements.
