Review on π Multipurpose LED Tester for LED TV Backlight and Constant Current Driver Board in LED Lights Repair - Output Range: 0-330V by Francisco Taylor
Great desktop addition
This is a really good DC source with high potential. It works well for its intended purpose - checking the TV's LED backlight. I recommend setting the "high current" switch to 20mA, by default it's all the way out, which is WAY big for most LEDs. When connecting the probes to the LED for the first time, the brightness increases from "off" to "off". "Set Current Limit" is a nice feature. Build quality is decent. The switches don't inspire confidence, but they work. Note that the voltage displayed (up to 330 VDC!) is present at the probes when they are not connected to the circuit under test. BE CAREFUL! This excitement will blow your mind!
