Test Power Supplies
The variability of the voltage regulating transformers makes them ideal for inclusion in test power supply setups. The lack of waveform distortion and fine control mean that the exact conditions required can be supplied. Whether providing a buck/boost system working around the available supply voltage or for full range variation and safe starting a system of a voltage regulating transformer, a fixed ratio transformers and a control can be provided to suit your specific application.
