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 railroad and industrial sectors.
The maximum available inverter power is 500 kVA (3~) or 200 kVA (1~).
Decades of use in telecommunications, railways, power stations, air traffic control, hospitals and industry speak for the high quality and reliability.
Inverter plug-in modules are available for smaller outputs (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:

  • Transistor inverter with PWM technology
  • Isolating transformer in the inverter output
  • Electronic bypass
  • Manual bypass

Features and advantages

  • Efficient and cost-effective maintenance and servicing due to well thought-out unit design
  • Highest availability and long service life
  • High control dynamics (> 4 ms)
  • Simple display and operation through TFT display
  • High performance available:
    single-phase up to 200 kVA, three-phase up to 500 kVA
  • Two-stage fan monitoring of the power units (warning, shutdown)
  • Parallel operation of up to eight units (up to 1500 kVA in the system)
  • Many custom options available
