Power supply units
Power supply units
Upon a customer requirement , we can carry out power supply units for other supply voltages, untipical voltages and output currents, e.g. low power units for the local dedusting systems.
This devices can be adapted for operation in optional weather conditions
Rectifier unit
The rectifier unit constitutes a tank filled with a transformer oil. A transformer high voltage rectifier, a current limiting choke, achoke counteracting an overvoltage and a potential divider are mounted inside the tank.
The following devices are mounted in the connecting box:
It is possible to make the dislocation of wheels position by 90°. The degree of protection of the rectifier unit (without the connetcting box) is IP 54. It is possible, upon a costomer request, to seal the connecting box to reach the degree of protection as high as IP 54.
The rectifier units can be additionally equipped with an earthing isolator (it can consist of 2 sections for a high voltage upper lead).
