HY5020E is a high current, high voltage switching DC power supply; this high quality voltage regulator is one of the most stable and powerful DC power supply from Mastech, with maximum DC power of 1000W. This high quality power supply has two levels of control over both current and voltage outputs (coarse and fine), which can be continuously adjustable at 0-50V DC and 0-20A. The unit comes with 2 LED displays, providing accurate and clearly visible readout for the voltage and current value. This unit has toggle switch at the back that allows you to operate it in 110V AC or 220V AC. Retails well over $550.

If you need a power supply for any applications with reverse EMF, including DC motors, slot cars, LEDs, battery charging and equalizing, electroplating and anodizing, please see our updated model with over-voltage protection.
