Isolation transformers for patient environments

The range, called Promed, has been designed for use with medical and nonmedical electrical devices in patient environments to provide safe galvanic separation between primary and secondary windings (double and reinforced insulation). The transformers have low leakage currents and meet air and leakage clearances required by the EEC guidelines for medical products in the Medical Directive 93/42/EEC.

The Promed range units all feature an encapsulated, toroidal-core transformer, which has minimum stray fields, and reduces capacitive coupling between the primary and secondary windings. There are a number of options available and these include a current in-rush limiter, an earth-leakage monitor and short-circuit/ overload protection.

All units in the range have a standard footprint of 300 x 300 mm and are stackable.
