Isolating transformers Isolating transformer, IP43 / IP44 Type LF-GS & LF-GY 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 environ- ment such as dust, humidity and corrosion. Short circuit proof with glass tube fuse on the secon- dary side, and also protection against extremely high temperatures with built in thermal fuse on the pri- mary side. LF-GS are supplied with terminal blocks and cable glands. LF-GY are supplied with 2 meters Euronet-cable, plug and American plug with protec- C tion cap. Compact design, fixed installation. Applications: Designed for equipment that requires main voltage/ line voltage at 115V (110-120V) e.g. electrical equip- B ment from USA and Canada and for reducing 400V A main voltage/line voltage to 230V. Galvanic partition between the primary and secondary side protects in- stallations and equip-ment by generating a new sys- tem in which any earth faults are eliminated. Crea- Wiring diagram tes a new symmetrical earth point (M) secondary.
