Short Killer - HR1520 - Controled Power Supply
Short circuit tester.
It's hard to find a short circuit without a little help.
With this controlled power supply, you can inject a precise current into the circuit.
At the point of the short-circuit, there's a temperature effect that you can control.
High current means you're causing a high temperature at the short-circuit point.
Low current means that you cause a low temperature at the point of the short circuit.
Depending on the circuit you're repairing, you can modulate the current and temperature at the short-circuit location.
Then all you have to do is measure the temperature and find out where the short is.
Now all you have to do is remove the problem.
