This high and low voltage cutoff circuit helps to protect the costly equipment like TVs, air conditioners, Refrigerators, etc. from high voltages as well as low voltages. This circuit helps to save ...

This inexpensive circuit can be connected to an air-conditioner/fridge or to any other sophisticated electrical appliance for its protection. Generally, costly voltage stabilizers are used with such ...

As noted in NFPA 70B, insulated-case and molded-case circuit breakers should be kept clean of external contamination (Comstock/Stockbyte/Thinkstock). Low-voltage ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

Low-voltage circuit breakers are predominant in virtually every electrical power system. Several years ago, Shermco Industries surveyed NETA-accredited companies for the IEEE Electrical Safety ...

We got a lot of really great feedback about low battery cutoff options in the comments section of Monday’s replacement battery post. To refresh your memory, some power tool batteries were replaced by ...
