Electrical power supply transformer Thermosystems Srl

Safety transformers of the series TS TSF are particularly indicated to power the temperature monitors and temperature controllers designed for a supply-voltage of 12 Vac.
They get produced in "closed manufacturing", with a plastic box provided of mounting lugs to permit a quick mounting; the electrical connections get done through screw connectors.
TS TSF B and TS TSF D are produced according to EN 60742 norm and defined "safety-transformers", that is why they can fit applications for very low safety voltage on the secondary circuit and for high insulation voltage between the primary circuit and the secondary one.
The protection from short-circuits and overloads is guaranteed for the TS TSF D through an incorporated non self-resetting thermal cut-out, while TS TSF B needs the insertion of a external fusible with the indicated characteristics.
