Testing power supplies and batteries requires current loads capable of sinking large current and dissipating substantial amounts of power. A simple but accurate current load can be built using just a ...

Figure 1 shows an 8- to 40-V input, 5-V output at 4-A maximum load current, dc-dc converter. It uses two LT3430 60-V monolithic, 3-A (peak switch current) buck regulators in parallel.

Single-channel high-side load switches provide an effective way of applying or removing power to a load, particularly to removable peripherals powered through a USB port. The AP22913A load switch ...

Unlike conventional resistive loads, the "dummy load" maintains a constant but adjustable load current for voltages in the range of 1.2 to 50 V. Both the power MOSFET and the sense resistor are ...

The ASCO 4800 Load Bank Models with 100kA Short Circuit Current Rating provides: Increased worker safety Helps with complying with recent NEC® Article 409 updates. Flexibility for a wide range of ...

The module can also monitor the load current. If a load powered by redundant power supplies draws more current than a single power supply can provide, this essentially defeats the redundancy. At this ...
