0-30V 0-5A 150W Variable Regulated DC Power Supply with USB socket This laboratory-style switching power supply will be at home in any shack. It is compact in size (200 x 140 x 95 mm) and light in weight (1.25 kg), and it offers variable voltage and current limiting settings.
It has three separate digital LED displays, showing DC voltage, as well as the current being drawn in amps and power consumption in Watts of any connected device. A current limit can also be set to prevent any connected device drawing more than a specified amperage.
The PSU has both coarse- and fine adjustment controls for voltage and amperage, as well as a USB charging socket on the front panel. There is also a handy ground terminal for DC earthing. A temperature-controlled cooling fan keeps the operating temperature constant under load.
