GR9 and GR9A Power Converters
GR9 is an AC/DC power converter developed by SECOM.
This device has been designed to cover a lower current range in order to provide an extremely compact and alternative solution to other SECOM products.
The converter is available in different configurations, with a current range that varies between 200Adc and 1750Adc and a supply voltage that ranges between 400Vac and 690Vac.
It is an air-cooled solution and each converter is equipped with line fuses and snubber filters.
The GR9 series three-phase converters are offered in different configurations and in different construction types.
The available configurations are the following:
- Three-phase diode rectifier
- Three-phase thyristor rectifier
- Semi-controlled three-phase rectifier
- Semi-controlled three-phase rectifier and internal braking unit.
The construction typologies:
GR9: converter with module semiconductors with current range from 200A to 1250A
GR9A: converter with disc semiconductors with current range from 500A to 1750A
GR9F: converter with module semiconductors with current range from 200A to 500A with cart option
GR9AF: converter with disc semiconductors with current range from 750A to 1750A with cart option
GR9_CHT: semi-controlled three-phase converter and internal braking unit with current range from 250A to 750A
