Product Description

This is brand new professional DC regulated power supply from Mastech, Model number HY3005D-3. This high quality power supply has three outputs: two outputs are continously adjustable at 0-30V DC and 0-5A, and the third output is fixed at 5V DC and 3A. What's more, the two outputs can be used either in independent, series or parallel mode, providing either two independent outputs, or one output with twice the voltage or twice the current output, up to 60V or 10A. The unit comes with 4 backlit LCD displays, providing accurate readout for the voltage and current value for both outputs. Unlike our competitors selling unsupported copycat products, we do standby our product and will offer full warranty service, and any other technical services needed. Please email us with any questions! Additional specifications: Input voltage: 110V AC and 220V AC switchable; Line regulation: CV <= 0.01% + 2 mV, CC <= 0.2% + 2 mA; Load Regulation: CV <= 0.01% + 3mV, CC <= 0.2% + 3 mA; Ripple noise: CV <= 0.5 mV RMS, CC <= 3 mA RMS; Protection: constant current and short-circuit protection; LCD reading accuracy: +/-1% for voltage and +/-2% for current; Environment: 0-40C, relative humidity < 90%.

Customer Reviews

Mastech Power Supply
Great item. Full functionality at a minimal cost. Build quality and feel is excellent.
I highly recommend this unit or similar from Mastech.

Good general purpose supply.
My only complaint is that there is no fine tuning of the parameters. If you need precise voltages, get the single supply units which have coarse and fine adjustments for voltage and current.

Great price point, check assembly
This is a great price and a pretty good product. When I took the product out of the box, I heard a clinky rattle, like a screw was loose. Opening the case, I noticed a heat sink was out of place and causing the rattle. After reattaching the heat sink, the system powers up fine. I suspect to provide the supply at such a low price, final inspection and burn-in testing was limited.
Otherwise, I am really happy with this product.
