NCA / MCA Autoranging Power Supplies

The NCA/MCA series is an auto ranging power supply design in which the power supplies operate over the full range of their output voltage & current, up to the units maximum rated output power. This results in an operating range which is up to 3-times wider than that of a more conventional power supply. When fitted with the optional computer interface, the MCA/NCA series become versatile programmable power supplies. In principle, the rectified line voltage drives a square wave generator, whose AC voltage is transformed, rectified and filtered, producing the output voltage. For regulation, the square wave voltage is pulse width modulated.
