## Description

VOLTEQ HY3020D is a brand new lab grade DC regulated power supply, an improved version of the HY3020D we carry for years under Mastech brand. This highly stable, high quality DC power supply has an output continuously adjustable at 0-30V DC and 0-20A. 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 removing the short circuit protection, so you can short the output to set the current limit; and 10-trn pot for voltage adjustment; as well as fan/heat sink combination for cooling.
