Organ transformer (3x42VAC)
The HEUSS organ transformer is a power supply which meets the requirements of a safety transformer (SELV / PELV) according to DIN EN 61558-2-6.
This can be used to drive 42VAC HEUSS stop magnets.
The composite unit will be shipped in a sheet-steel enclosure with wall-mounting brackets.
Screw-in cable glands on the underside allow strain-relieved insertion of conductors.
At the bottom there are phase failure indicators which also allow an electrical layperson to determine by mere visual contact whether a primary side phase has failed.
Primary and secondary side fuses allow for proper connection to your instrument.
Primary: 400VAC (Different voltages on request)
Different currents on request
Case sizes vary depending on amperage.
400mm x 300mm x 200mm: 5-55A
600mm x 400mm x 200mm: 60-100A
To calculate the current requirement of the 3x42V sliderl motors, you can calculate 1A per motor (not per stop) incl. the necessary safety pole resistance and then round up to the next "step".
For 12 motors, for example, it would be 12x1A = 12A, rounded up to the next "step" is 15A required.
