Note:
Two single-phase step transformers (in V-circuit) according to DIN EN 61558, VDE 0570, part 2-13. Common exit and entry coil. Coils without galvanic separation. Transformer within a plastic or steel case with a step switch, protection system IP 43. Connection to terminals, safety class I, ta 40°C, 50/60 Hz.
Options:
* Secondary standard transformation: 3 x 80 - 100 - 140 - 200 - 280 - 400 V * These transformers are suitable as in-line transformers for electrical consumers, e.g. speed control of 3-phase ventilated motors. * Wiring two single-phase transformers in V-circuit produces a three-phase system suitable for this application.
