Amazingly small switch mode power supply but has all the features you would expect of a larger power supply - large analogue Volts and Current meters, voltage adjustment 11 to 15V DC, front panel red warning LED, short circuit & overload protection, cooling fan, and large terminal posts (on rear)
With the Noise Offset knob you can adjust the switching frequency of the power supply from 19KHz to 31KHz. This function is especially designed for radio communication use. If you get noise from your transceiver then simply by turning this knob clockwise or counter-clockwise you can tune the noise out!
