Power Supply / Industrial Inverter / Railway Approval
Static Inverters
Type WR-5080 (1~), Rated power up to 200 kVA
Type WR-5081 (3~), Rated power up to 500 kVA
Type WR-5073 (inverter plug-in modules)
Scope of application
Our static inverters are designed as uninterruptible power supplies (inverters in combination with rectifiers and batteries) to bridge short-term interruptions, mains failures, voltage fluctuations, frequency fluctuations or generally to compensate for mains disturbances in the field of data processing and in systems of automation and control technology. They are used to supply AC consumers, primarily in the railway and industrial sectors.
The maximum available inverter power is 500 kVA (3~) or 200 kVA (1~).
Decades of use in telecommunications, railways, power plants, air traffic control, hospitals, and industry speak for their high quality and reliability.
Inverter plug-in modules are available for smaller power ratings (see brochure).
Essential features
Gustav Klein inverters type WR-5080 and WR-5081 are equipped with a color touch screen display and consist of the components:
