What is the maximum ON/OFF frequency of a solid-state relay (SSR) for AC loads?

The maximum ON/OFF frequency of a solid-state relay (SSR) for AC loads typically aligns with the capabilities of the device and the nature of sinusoidal AC waveforms. Solid-state relays are designed to switch AC loads and often can handle frequencies significantly higher than the lowest option mentioned.

When considering the provided choices, the maximum ON/OFF frequency of 10 Hz is relatively low for solid-state relays, which can handle much higher frequencies due to their fast switching capabilities. SSRs are generally utilized in applications where switching at tens to hundreds of hertz is common, allowing for more efficient control of AC loads.

The other choices, 100 Hz, 50 Hz, and 60 Hz, are more indicative of typical AC power frequencies (50 Hz being standard in many regions and 60 Hz in others), rather than limits on switching frequencies for SSRs. However, SSRs are capable of operating well above these AC frequency standards, which means they can effectively perform switching tasks at higher rates suitable for various applications in industrial, commercial, and residential settings.

Therefore, while it’s clear that many SSRs can switch at frequencies much higher than the 10 Hz choice, this specific option mistakenly presents a limit that doesn’t align with typical
