A continuously variable power supply that is fed by a plug top PSU. The unit offers a variable voltage from 1.2V up to either 8V, 11V or 14V depending on the plug top PSU used. Current of up to 1A is available making the unit suitable for powering MES lamps, motors, buzzers, LEDs etc. The output is smoothed and regulated making it suitable for powering electronic circuits. The use of a plug top PSU means that there are no trailing mains leads, leading to safer operation. The required plug top power supplies are:

• 9V, 1.6A with 2.1mm plug for output up to 8V
• 12V, 1.6A with 2.1mm plug for output up to 11V
• 15V, 1.6A with 2.1mm plug for output up to 14V
