We were approached by a client who was experiencing problems with inrush start up currents on conventional transformers. On long cable runs these high inrush currents (typically 10 - 15 times the full load current of the transformer can be experienced) were causing excessive cable voltage drops and causing other equipment on the supply to drop out.

After some discussion with the c... (read more)

Custom built power supplies can be designed and manufactured to your exact requirements. They can be single phase or three phase input, and AC or DC output. The output can be fixed voltage or variable voltage: variable output may be adjustable in fixed steps or be continuously variable. The output(s) can range from a few volts at several thousand amps to several thousand volts at a few m... (read more)

Available from stock CE marked. Does not introduce waveform distortion consequently minimising EMC problems single and three phase models are available over a wide range currents.

These superbly built variable transformers have high quality, self aligning carbon brushes spring loaded onto a plated copper track to provide smooth and long lasting power control.

Our transformers in this range are suitably protected by a sheet metal case. They are normally wall mountable up to 2500VA and floor standing above this rating although portable styles can also be supplied. Many requirements are for isolation and/or conversion of three phase machines, or creation of a neutral where none is available. Our standard metal cases are IP23, but we can supply u... (read more)
