Isolating transformers Isolating transformer, UL-approved Type SUL Open single-phase isolating-/control-transformer with separate insulated windings and protected against dust, humidity and corrosion through complete impregnation in heat tempered varnish. UL-approved and produced according to DNV, Lloyds register of shipping and Bureau Veritas regulations which include 45°C ambient temperature. Compact design, fixed installation, easy mounting in cabinets or switchboards. Applications: Industrial isolating-/control-transformer suitable for installation which require protective separation between input and output. SUL84A, SUL84B, SUL96C & SUL96C can be mounted on 35mm DIN-rail. The transformer must be protected against overload and short circuit in the installation.
