Frequency converter with fixed output frequency / railway approval
Frequency converter
Type FW-5443 (1~) and FW-5444 (3~)
Type FW-5444-DB (3~) especially for railroad applications
Scope of application
With our frequency converters, which we offer with outputs of up to 500 kVA, AC consumers can be supplied with constant voltages, deviating from the input network.
Frequency and voltage are adjusted to fixed parameters. Input and output voltage are galvanically isolated.
The frequency converters contain the tried and tested components from our industrial UPS systems and are characterised by maximum reliability, clear design and ease of maintenance.
In addition to the classic frequencies of 50 Hz, 60 Hz, etc., solutions for railway applications are often implemented with e.g. 16.7 Hz.
If you are looking for a unit with freely adjustable output voltage and frequency, you will find it under the section “Test and simulate” as
AC source/sink.
Essential features
- Galvanic isolation between input and output
- Sinusoidal pick-up current, low reactive power consumption
- Color TFT – touch screen display as display and operating unit, incl. Message memory for fault diagnosis
- High test voltages acc. EN 50124-1 from the railway sector
Customised adaptations
- Specific electrical parameters, e.g. frequency/voltage, short-circuit currents, overload behaviour
- Specific electrical parameters, e.g. frequency/voltage, short-circuit currents, overload behaviour
- Customer-specific equipment, e.g. protective devices, fan monitoring, interfaces
