Isolating transformer for supply of medical rooms
TTMS 4000/230
Characteristics
General data
The isolating transformers of the TTMS series are designed for supplying medical rooms of group 2 according to EN (IEC) 61558-2-15 in conjunction with EN (IEC) 6034-7-710, offering a flat, horizontal alternative. The transformers ensure safe galvanic isolation and stand out with low short-circuit voltages and no-load currents, as well as high efficiency.
Benefits
› PTC resistor built into every coil to set up an external monitoring unit for protection against overload
› Very good switch-on behaviour thanks to reduced starting currents
› Very good corrosion protection and low noise thanks to BLOCK IMPEX vacuum impregnation
› Contact protected screw connection terminals complying with UVV BGV A3
› Simple mounting due to robust metal fixing rail with 8 oval slots
