Ray is a capsulated three-phase non short circuit proof transformer with power range up to 2000 kVA. Designed and tested according to EN61558-2-4 or IEC60726/IEC60076 (depends on the power). Standard types supplied with separate primary and secondary windings.This generates “a new system” in which any earth faults are eliminated. Steel plate enclosure, degree of protection IP23 or higher.

Ray is an ideal design for transforming voltage up or down or for installations which require
a galvanic partition between the primary and secondary voltage. Protects installations and equipment by generating “a new system” in which any earth faults are eliminated. E.g. electric motor, compressor, cooling plants, automatic wash-ing machines, and to uphold IT or TN-S systems. Custom designed types with other voltages, frequencies, electrostatic shield between primary and secondary, regulations, tappings, transport wheels or other features are available upon request.

EN61558-2-4:1997, EN55014:1993 (EN55014-1:1997), EN61000-3-2:1995, EN61000-3-3:1995, EN55104:1995, (EN55014-2:1997), EN50081-1:1992, EN50082-2:1995

based on the following directives:
L.V.D 73/23/EEC, 93/68/EEC,
EMC 89/336/EEC, 91/263/EEC.

Furthermore – DOE can provide marine class certification (DNV, BV, LR, RMRS, RRR, RINA and more) for every RAY transformer. Please note that only the transformers with the highest power are required to have a class certification. Our sales manager will clarify the necessity of marine certification during the offering process.
