The global demand for green energy sources is driving strong market growth for solar power systems. Although a great deal of development work is still focused on making PV (photovoltaic) energy ...

My introduction to circuit protection came at the tender age of eight. Being a curious lad with an inventive – and apparently self-destructive – bent, I decided to make my mother a lamp. I put a hose ...

Benefits of an e-fuse solution. Optimal voltage range for e-fuse applications. Target applications for e-fuse devices. The trend toward higher bus voltages creates the need for a robust circuit ...

In Part 1, we looked at how to size a branch circuit and walked through a simple example. So if you’re sizing a feeder, why don’t you do it the same way? Except in cases where a feeder is also ...

Home inspectors do not need long to spot a bad circuit extension. The wrong fix leaves a visual trail of extension cords, overstuffed boxes, and improvised splices that signal both code violations and ...

LED luminaires require precise power and heat management because LEDs convert most of the electrical energy they receive into heat rather than light. Without adequate thermal management, this heat can ...

[Mark Rehorst] tells us about a tragic incident involving an untimely demise of $200 worth of motor driving hardware, and shares a simple circuit so that we can prevent such tragedies in the future.

“Each output channel of the S8AS2 is equipped with independent electronic circuit protection. In the event of an overload or short circuit, only the affected channel is shut down, allowing other ...

The usual way of preventing a small motor from drawing too much current is to install overcurrent protection in the form of a circuit breaker or some other kind of limiter. But installations that ...
