RUHSTRAT variable toroidal transformers are manufactured according to DIN VDE 0552. A special advantage are the have galvanically refined decks of RUHSTRAT variable toroidal transformers. They assure a constant transfer resistance and increase service life and operation safety.
- single-phase and three-phase design
- for normal and heavy-duty operation according to VDE 0552 § 5
- power range from 0.2 kVA up to 30 kVA
- voltage range up to 500 V
- frequency range from 50 to 400 Hz
- degrees of protection: IP 00?IP 54
- kinds of circuits: economy circuit, galvanically separated winding, additional exciting circuit, special circuits
- kinds of regulation: electronic follower control devices, stabilization of current and voltage
- desired value: by potentiometer, voltage or current
- actual value: all physical quantities which can be transferred into electrical values
Example of use:
- e. g. voltage adjustment on lighting installations, electrical heat resistors, rectifier plants, plastic presses and spraying machines, high-voltage plants and high-current plants, stabilization of current and voltage, laboratory installations and test equipment, measuring and regulation circuits, air engineering etc.
