Littelfuse, Inc. announced the expanded offering to the industrial Solid-State Relays (SSRs) family of products. The ...

the zero-crossing detection will wait until the AC signal crosses zero before switching. Another type of SSR, called a ‘random turn on’ solid state relay, is used to implement dimming.

First off, here’s a proven design of an adaptable solid-state relay (3~32V DC control input → 230V AC switch output): At this point, note that zero-crossing SSRs are widely used when a simple on/off ...

Littelfuse expands its SRP1 family of industrial SSRs for simple heating applications that require reliable and cost-effective switching.

These modules are also similar to dc solid-state relays. Ac input load-sensing modules generate a logic-level voltage (typically TTL or CMOS) that corresponds to the presence or absence of an ac ...

As [Mic] often got requests to make high-power switching boards, he recently finally gave in and designed the one shown above based around a solid-state relay ... mains into an AC optocoupler.

The S2840B Series of normally closed, ac solid-state relays is designed for controlling medium-sized loads. The relays feature back-to-back SCR outputs capable of switching 40 A at line voltages to ...

On the output side there are back-to-back mosfets allowing ac or dc to be switched ... above which capacity linearly declines to 1A at 85°C. A similar solid-state relay, VO1401AEFTR, was introduced at ...

MALVERN, Pa., Dec. 11, 2024 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a 1 Form A solid-state relay offering a 600 V load voltage and isolation voltage of 3750 ...
