Single-phase short circuit proof isolating transformers designed and tested according to EN61558-2-4. Separate insulated windings moulded in self-extinguishing Polyurethane and capsulated in plastic. This protect the transformer against hostile environment such as dust, humidity and corrosion. Short circuit proof with glass tube fuse on the secondary side, and also protection against extremely high temperatures with built in thermal fuse on the primary side. Supplied with terminal blocks and cable glands. Compact design, fixed installation. Designed for equipment that requires main voltage/line voltage at 115V (110-120V) e.g. electrical equipment from USA and Canada. Galvanic partition between the primary and secondary side protects installations and equipment by generating “a new system” in which any earth faults are eliminated.
