This system introduces an AC touch-controlled solid-state relay (SSR) capable of handling input voltages from 100V to 250V AC ...

Two new patented circuits control ac power to resistive and reactive loads with minimal EMI. They are applicable to single and multiple ac phases and varying ac frequencies. Switching ac power on and ...

One advantage of solid-state relay (SSR) over conventional electro-magnetic relay (EMR) is its tear and wear free operation. S201S01 from Sharp is a good example. Here is the circuit diagram of a DIY ...

Finding a 480V-ac solid-state timer having zero-crossover switching may prove to be an impossible task. Most solid-state timers are rated at only 1A and have voltage ratings no higher than 240V ac.

Solid-state relays are among the switching elements that now use materials allowed under the RoHS mandates. The specifications of these devices typically are identical to those of non-RoHS compliant ...
