ST 100 - ST 300 - ST 500 Safety Transformer according to EN 60742 for Heating Cables with Nominal Voltage of 42 V~

The safety transformers ST 100-500 with separate windings are required for heatings with nominal voltage of 42 V~.

In case of a short-circuit, these transformers are protected by an integrated thermal fuse and against overload by an exchangeable glass-tube fuse.

The power cable of the primary 230 V~ input has a flat plug which complies with the European Norm. The secondary 42 V~ consumer outputs are connected by clamps.

The transformers are molded in outer casings.

Please ask for further output currents or output voltages.
