Single-phase isolation transformer for command, control, and general uses. Input voltage of 230 or 400 Vac and two possible output voltages, 115 or 230 Vac, each selectable via jumpers. The transformer provides 40 VA of power and has an IP-00 protection rating. Depending on the connection of the two output secondary voltages, the transformer can supply either 115 Vac with a current of 0.34 A (apparent current), or 230 Vac with a current of 0.17 A (apparent current).

The main application of this type of transformer is for command and control in industrial automation systems and for general applications. They are intended to power electrical devices where galvanic isolation between circuits and/or voltage level adaptation are required.


These types of transformers are reversible.


The transformer can be secured with screws or on a DIN rail. It must be secured to the DIN rail using the accessory designed for this purpose, reference KITDINKF1.5. This accessory is not included in the scope of supply and must be purchased separately.
