MASTECH DC Variable POWER SUPPLY 30V 20A Memory RS232
For sale is a brand new, microprocessor controlled, highly stable, lab grade variable DC power supply from Mastech, Model number HY3020MR. HY3020MR is one of the most stable and powerful DC power supply from Mastech. This high quality 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. 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. The digtial control and keypad 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 with a computer. Retails well over $600. Please email us with any questions, our hard-working staff will answer every email in no time!
