Mastech HY3020D is a lab grade regulated linear DC power supply, it is one of the most stable and powerful DC power supply from Mastech, and the most powerful linear power supply we carry. This high quality variable power supply has two levels of control over both current and voltage outputs (coarse and fine), which can be continuously adjustable at 0-30V DC and 0-20A. The unit comes with 2 bright LED displays, providing accurate and clearly visible readout for the voltage and current value, both in well-lit and dark environment. LED displays are much brighter nowadays, more durable than LCD displays; for this reason they are the new trend in the instrument panels. This unit has toggle switch at the back that allows you to operate it in 110V AC or 220V AC. Retails well over $400.
