You use an active-load test circuit to ensure that a power supply for a microprocessor or for other digital loads supplies 100A transient currents. This active load can provide a dc load for a power ...

When it comes to testing power supplies, it’s useful to have a dummy load to put the gear through its paces. While it’s possible to just use some old heating elements or other big resistors, an active ...

Bench electronic loads are usually rated for voltages less than 100V, which make it difficult to test high-voltage power supplies. This Design Idea offers an alternative: an inexpensive electronic ...

There are three main elements to our testing equipment which are each there to provide us with different pieces of information to judge the quality of a power supply: SM-268 Active Load Tester This ...
