VOLTEQ HY3003D is a brand new lab grade DC regulated power supply, an improved version of the Mastech HY3003D we carried for years. This highly stable, high quality DC power supply has an output continuously adjustable at 0-30V DC and 0-3A. What's more, the unit is equipped with coarse and fine controls for adjusting the voltage and current outputs, making it extremely easy to set the output to your desired level. The unit comes with 2 bright LED displays, providing accurate readout for the voltage and current values.
The improvement includes adding over-voltage and reverse-voltage protection to make it more robust, removing the short circuit protection, so you can short the output to set the current limit; and a Hi/Lo button that allow you to cut the current in half when it's pushed.
