Inverter
Transistor-inverters are divided in following main Groups according to the required dc-input voltage, power and application:
- Single phase inverters Type WR-5080 (up to 200 kVA)
- Three phase inverters Type WR-5081 (up to 500 kVA)
- Inverters in modular design with a DC input voltage of 24 V – 220 V can be found in our special brochure. Type WR-5073
Inverter Type WR-5080 and WR-5081
