Product Details

TTMS Series Medical Transformers

The TTMS series of isolation transformers have a rated input of 230 V ac and a rated output voltage of 115 V ac and 230 V ac. These isolation transformers are protected from overload by a PTC resistor that is integrated in every coil to set up an external monitoring unit. Reduced starting currents enable excellent switch-on behaviour and these isolation transformers feature low short circuit voltage and very low idle current. BLOCKIMPEX vacuum impregnation allows for low noise and excellent corrosion protection. With a robust metal fixing rail featuring 8 oval slots, these isolation transformers are easy to mount.
