Description of 🧪 Dr Meter 4 Digital Multifunctional Laboratory Switch

▶ 【High Precision, Wide Range】The DC power supply is a professional power regulation device that designed with crystal clear, backlit 4-digit LED display of voltage, current, and power. Precise accuracy: 00.01V and 0.01A. You can easily tune it within 0-30V and 0-10A. ▶ 【5V/2A Output & Auto Power Calculation】Run out of power? Now you can charge your phone, repair phones and more through the 5V/2A USB interface. Moreover, this device intelligently calculates output voltage and current into power and displays the value on its large screen. ▶ 【Excellent Heat Dissipation】Equipped with a big fan controlled by intelligent temperature control sensor and multiple heat radiation grooves on both sides, Dr.meter 30V/10A power supply can quickly disperse heat during operation, greatly improving its working efficiency and lifespan!. ▶ 【Safe and Reliable to Use】Safety is our priority. You can not expect more for safe, productive work since the power supply comes with grounding terminal and multiple protection of over current, over heat, and over voltage. ▶ 【User-Friendly】Frustrated by bulky devices? This one weighs less than 2kg and measures only 285 x 128 x 145mm, perfect to be taken for laboratory, electronic, communication equipment maintenance, products line, scientific research, teaching units and other requirements thanks to complete test probes and output cable with alligator clips.

Surprisingly good for its price.

Connected to my DMM to test performance and accuracy. Both voltage (30V) and current (10A) are as advertised and match my DMM to within 1 or 2 counts of the last digit. It's a switching power supply, so it's pretty light. Note that the negative comes with a shorting bar connected to ground - flip that out before you forget and blow up something that has a different ground. CC (Current Control) point until it's already supplying power - it may be too late if you forget to set it before turning…

Pros
  • Safe and reliable to use
Cons
  • Some small things

Great value for money

I'm an electrical engineer working from home during the pandemic. My employer's lab is full of test equipment from Fluke, HP/Agilent/Whatever-As-Founders-Spin-in-Their-Graves, Tektronix, and B+K. I got used to good things a long time ago. While I haven't used this power supply to test actual performance, I can say it's well built and totally worth the price. Good bright display. Mounting pins spaced 3/4" apart to fit your Pomona banana forks. Detachable IEC power cord and 120/220V AC switch…

Pros
  • Excellent heat dissipation
Cons
  • boring packaging

Works well - accurate to within a few percent

I already had a cheap power supply that worked fine except that its voltage/current readings were a bit erratic. I really had to use my DVM if I cared about the details. This power supply is much better in this regard. The meter reading is within a few hundredths of a volt or amp compared to my DVM. I would also add that despite the higher amperage rating it is noticeably lighter than my previous power supply (which is itself a switching power supply). Completely transformerless? I do not know.

Pros
  • 5V/2A output and automatic power calculation
Cons
  • Something else
