HY3020MR is a microprocessor controlled, highly stable, professional grade DC regulated power supply, and one of the most stable and powerful variable DC power supply from Mastech, with maximum output power of 600W. This high quality DC power supply has two levels of control over both current and voltage outputs (coarse and fine), with outputs digitally adjustable at 0-30V DC and 0-20A. It comes with 2 LED displays, providing accurate and clearly visible readout for the voltage and current value. The digital control and key pad entry allows easier adjustment and better control for set point, as well as better stability and accuracy for the output. What's more, you can also use the software included to control this power supply via the RS232 port using a computer. Retails well over $500. Unlike our competitors selling unsupported copycat products, we do standby our product and will offer full warranty service, and any other technical services needed.
