Three-phase power converter GR19
The GR19 converter series are used for DC motor control application.
These are totally controlled three-phase bridges in unidirectional (non-regenerative) and bidirectional (regenerative) versions.
This product was created to respond to the requests for applications that require high currents and high voltages.
The converter is equipped with protection fuses and snubber filters that work against overvoltages.
To simplify maintenance of the unit, the converter is equipped with handles for extracting the thyristor directly from the stack without having to remove or disassemble the entire module.
Maintenance is therefore simplified and allows any operator without a high level of preparation to extract the thyristor or fuse and replace it.
The voltage range of the GR19 converters ranges from the classic 400Vac to 1250Vac (Vrrm thyristor 4200V). The maximum current that can be delivered from the bridge is 5000A.
