Voltlog #127 – 0-60V 0-10A 1mV 1mA Panel Meter Review

So I discovered this module a few months ago and it’s been sitting in a box since then, I almost forgot about it, until a few days ago when I decided it will be a good idea to do a video on the subject.

Let me give you a few details on the specs of this module and as usual it’s pretty difficult to find the information as it’s the case with every new module coming out of China. First of all we have an input range of 0-60V and 0-10A and a 5V rail is needed to power the module itself. It has a voltage measuring accuracy of ±0.2% + 0.2% full scale which sounds strange because these figures are usually given in a percentage plus or minus a number of least significant digits. The current measuring accuracy is ±0.4% + 0.3% full scale.

The meter is basically capable of measuring with a resolution of 1mv and 1mA (however the accuracy is quite bad, as shown in the video) which is quite nice and useful (not really useful with bad accuracy) for projects like DIY power supplies or DIY electronic loads. It can also display the power in watts with a resolution of 1mW as well as showing the load impedance.

Voltlog #122 – C5W LED vs Incandescent Bulb Temperature

Welcome to a new voltlog, in a previous video I showed these C5W LED bulbs that I got from ebay they were very cheap so I put them to a test and discovered they reached very high temperature in just 15 mins of running in free air which got me concerned, the fixture of this bulb could melt.

Voltlog #120 – Mini DC Power Supply Review

So I guess a gadget like this is worth 10$ because you could replace that linear breadboard power supply with a more efficient one, which will give you voltage and current display as well as adjustable output.

Here are some images I took during the teardown of the mini power supply:

Voltlog #119 – NEW 150W Dummy Load Review

Today we are taking a look at yet another electronic load. I found this one on Aliexpress, I think it’s a rather new model so let’s see what it can do.

Here are links to the 150W and the 180W version of this dummy load:

Voltlog #117 – Ebay Bussman DMM Fuses Fake or Genuine?

In this video we’re going to do some tests on these ebay fuses to try and determine if they come close to the specified ratings of the original fuse.

Voltlog #116 – UNI-T UT211B Clamp Meter Review & Teardown

today we are taking a look at the UNIT UT211B clamp meter it can do both AC and DC measurement and it has 1mA resolution on DC measurements and 0.1mA on AC. We’re also going to take a look at the DANIU P1600D test lead kit which has a bunch of accessories that might be useful.

Voltlog #115 – Pure Sine Wave Inverter Circuit Waveforms

This is a followup video on the 300W pure sine wave inverter I reviewed a couple of weeks ago.  A couple of people we’re curious how the output mosfets are switched in order to obtain that nice looking sine wave on the output.

Voltlog #114 – Aneng AN8008 Probably The Best $25 Multimeter

Today we are taking a look at the ANENG AN8008 multimeter. This product was sent to me by banggood.com free of charge for the purpose of this review. They also sent me an ESD mat, because I have two benches in here in only one of them had an ESD mat so I needed a second one.
