Variable 4 A/25V Power Supply

Variable 4 A/25V Power Supply
All workshops or laboratories must have a power supply for general purpose that can supply voltages and currents. This time we get a adjustable power supply with output voltages between 1.2 and 25V the maximum current of 4A. ┬áThis is very useful for laboratory power supply or workshop power supply. (more…)
