Digital Excitation Controller D-VO

Product Description

D-VO series includes 3 models:
D-VO (10024470), D-VO light (10024471); D-VO basic (10029001)
Hardware differences among the models are the following:
- D-VO, full feature variant
- D-VO light/basic without ethernet port for Modbus TCP/IP;
- D-VO light/basic without plastic cover on the top, then the protection grade is IP00 instead of IP20.
All the models are based on the same hardware (excluding ethernet port/cover), same firmware and same software releases, only Light version has the grid support feature inhibited.
