Transformer in which the primary and secondary windings are electrically separated by double or reinforced insulation to protect the circuit supplied by the secondary side against the risk of accidental simultaneous contact with earth and live parts or earthed parts that are live in the event of an insulation fault. Complies with standards CEI EN 61558-2-2 and CEI EN 61558-2-4. Primary supply with 230-400 VAC and separate terminals with ±15V for precise regulation of the input voltage. Use in continuous operation and fixing on mounting plates. Can be fixed on a top hat rail up to 160 VA with additional mounting lug for DIN rail (TM-C-DIN). Full power tap on all outputs.
