Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

In Part 1 of this two-part series, we presented a 3-phase, 480VAC motor circuit with its associated controls (Figure). We stepped through a logical, systematic approach to troubleshoot the main power ...

[fahadshihab], a young tinkerer, shared his circuit design for a simple remote control using 555 timers. Using a 555 calculator, he designed a clock circuit that would run at 11.99 Hz. Two transistors ...

Tone control is a type of equalization used to make specific pitches or “frequencies” in an audio signal softer or louder. A tone control circuit is an electronic circuit that consists of a network of ...

The circuit has been designed for the purpose of creating a portable unit of preamplifier that would function as standalone control for gutitars. TL062 – a low power JFET dual operational amplifier ...

Higher Capabilities for Safety-Rated Control Circuits A truly reliable safety control system must work even when some parts fail. Force-guided relays are unseen components that add another level of ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

Smart ICs increasingly handle complicated schemes such as field-oriented control. It is no secret that any equipment that either heats or cools is coming under great scrutiny as governments ...
