As many of you know I’ve been busy finishing my latest hardware creation, Myro:Air and as part of a certification process, the USB port on the back of the unit must be able to provide a stable 5V at both 1A and 2.1A loads. Long story short, it’s been quite the process to test the power supply consistently until I found this nice Programmable DC Electronic Load system. It’s marketed under many different brands like TekPower, Circuit Specialists & ProTek but it usually also contains the model number of 3710A and is made by Array. The best part is the price — $349 for the 360VDC/150W and $499 for the 360V/ 300W version.
I purchased the unit from Circuit Specialists and will post a full video review soon. It’s allowed me to easily test different component profiles as well as test the required overload protection of Myro:Air’s USB circuit. The unit also features a built in multimeter that can also measure the voltage of the circuit under load though I still prefer to use my DMM for more accurate measures. I’ll also demonstrate the PC software it ships with in the video.
Feel free to post an questions in the comments and I can answer then in the video.
