This circuit uses a few standard discrete components to provide a user-settable current-limit function with closed-loop performance. In addition, the limiter function can be turned on and off via an ...

Constant current limiting circuits are commonplace, but sometimes a constant power limiting function is desired instead. This can be because downstream loads, like DC/DC converters, present a constant ...

I use an old ATX PSU as a bench supply for my projects and needed a simple & cheap adjustable current limiting circuit. I use an old ATX PSU as a bench supply for my projects and needed a simple & ...

This current-limiting circuit, shown in this example as part of a small bench power supply, could in principle be used in conjunction with any dual-rail current source. The part of the circuit to the ...

Fault protection is a critical function of all power supply controllers. Nearly all applications require some kind of over-load protection. For peak current-mode controllers this is easily ...

Designed and dual-rated for AC and DC applications, the Eaton FAZ-NA and FAZ-NA-L series current-limiting miniature circuit breakers from AutomationDirect offer protection for application with up to ...

Bulletin 140G molded-case circuit breakers react up to three times faster to minimize downtime Industrial automation customers can improve their short-circuit protection with a new line of ...

Central Semiconductor has created a line novel of zero temperature coefficient current limiting diodes, packaged in DPAK and rated at between 27 and 575mA. Minimum voltages range across 1.5 to 2V – ...

Littelfuse claims that its CPC1561B Solid State Relay (SSR) is the highest current (1 A, 60 V) normally-open SSR currently available on the market to integrate both current limiting and thermal ...

Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...
