Transformers are intended for supplying devices requiring AC power supply insulated from 230V AC mains. On the output we get the AC voltage: 16V lub 18V. The transformer has protection: (1) protection in the form of a fuse in the power supply circuit (T 315mA/250V), (2) overload in the form of a thermal fuse 130° C. Input voltage: 230V AC. Power: 40VA. Outputs: 16V / 2.2Amp or 18V / 2.0Amp. Dimensions: 93 x 60 x 65 mm. Working temperature: -10° C÷ 40° C.
