TFM

Safety transformers with galvanic isolation provide a reliable supply to power circuits with the safety measures “protective separation” or “protection through shutdown”.
 Double or reinforced isolation between the primary and secondary sides protects SELV and PELV circuits. Safety transformers provide safety extra low voltages below 50 Vac or 120 Vdc.
