Single Output Switching 0-18V, 0-20A

The SPS-1820 - part of the series of switching power supplies for measuring instruments - has ruled out the inconvenience of big volume and heavyweight traditional power supply possesses. The output voltage and current is controlled by two variable resistors with coarse and fine regulation for more handy and precise adjustment. Features include: a more extensive range of input voltage (97V~133V for 115V and 195V-265V for 230V), reduction of power transformer size with high frequency operation, small, light-weight, high density power, efficiency rate up to 70%, auto control of voltage and current mode, and zero adjustment for the output of voltage and current.
