Specifications: Output DC Voltage: 0.0V – 30.0V Output DC Current: 0.00V – 4.00 A Input Voltage: 110V/AC, 60Hz or 220V 50Hz Voltage and Current adjustment Voltage regulation: CV <0.01% + 3mV, CC <0.2% + 6 mA Load regulation: CV <0.01% + 3mV, CC <0.02% + 3mA Ripple and noises: CV <1 mV rms, CC <3 mA, rms Operating Temperature: 0 - 102 F (0 - 40 C), Relative Humidity: <80% LCD Accuracy is within +/- 2.5% Size: 10 x 3 x 1 ¾ inches Weight: approx. 1.2 lbs Tekpower is a registered trademark in the United States, any unauthorized use of our trademark is a violation of both Federal and State trademark laws and could subject to liability for damages and penalties. Your feedback is not only important to us but also beneficial to other customers, therefore we’d like to invite you to submit a review for the Tekpower power supply!

Review: Exceeded expectations - Easy to use, clean power, solid regulation, and accurate. It outputs a maximum of 3.75 amps or 50 watts, whichever is lower. e.g. 3.33 amps at 15 volts, 2..08 amps at 24 volts, or 1.67 amps at 30 v. There's a software calibration mode but mine was spot on to my DVM, within a few hundredths of a volt so I didn't bother with it. The USB outputs are fixed at 5.1 v (a good thing) but you can set current limits at anything up to 2.5 amps and monitor actual current. Minor quibbles: The manual is poorly translated but the interface is pretty intuitive. The power button just controls the output so the unit stays on as long it's getting AC. Build quality is excellent overall but the included output leads are crappy. Much more compact and handy than an equivalent linear power supply. Highly recommended.
Review: This is a great, portable power-supply! - I was looking for a smaller adjustable DC power supply, for occasions when I don't want to drag out the big bench supply, or when I need portability. This Tekpower TP3016M (newer revision), is just the ticket. Being revised, mine does not have the issue with negative voltage when the output is off. The voltage and current ranges are quite impressive for such a small unit (roughly the size of a DMM). Some folks dislike the lack of a unit power switch, but I've personally found it not to be a problem.

### ⭐⭐⭐⭐⭐ Works great
*by A***) on November 8, 2017*

At first I thought that it was a bit pricey, but it's very well made and reliable. Besides, I've been using it so much that it pays for itself just by saving me time not having to look for adapters with the right amps and voltage. I "upgraded" it by taking the cord and plugs from an old universal adapter. I like that it takes up less space than most power supplies and unlike the picture on the box and site, the green display backlight is actually white. Round knobs would be easier/faster to adjust than pressing those rubbery buttons, but being able to instantly recall 5 stored settings somewhat makes up for it.
