To meet the demands of international clients world-wide, we have designed and built a variety of practical portable mains units to suit any requirement.

Whether you need a simple step-down transformer to convert UK 240 volts to USA 115 volts, or a full 125 amp stabilised distribution system, John Henry's can provide the solution. All systems are fully flightcased and are supplied with the necessary cabling.

The range includes:

Cycle Changers - to convert UK 50 Hz to USA 60 Hz.

Mains Distribution - from single 250v 4-way UK plug-boards or 115v 4-way Edison power strips to multi outlet systems.

Stabilisers - to give continuous, automatic, stable supply.

Transformers - to convert UK to USA or Japanese voltage and vice-versa.

Variacs - to give precise choice as to output voltage from 0-265 volts.

All John Henry's custom power units conform to IEE and 'Safety at Work' wiring regulations.
