Solid State Relays are common across a multitude of industries and devices and are enjoyed for their reliability, high anticipated service life, and fast switching capability. The H12D48125-10 is reliable SSR designed for use in switching loads of up to 12A.

Applications

The H12D48125-10 is a valuable component for a variety of applications, thanks to its fast switching times between 0.2 and 1.5 milliseconds and wide operating temperature range, as low as -20 and up to +80°C. This reliability makes the H12D48125-10 a good choice for industrial control systems, especially when long-term, reliable operation is essential. It can be used to switch large cable sizes and is especially suited for the switching of infra-red LEDs, where its fast switching times help significantly with LED brightness.

The H12D48125-10 is commonly used in modern households, especially for control of electrical and electronic heating systems, controlling the flow of electric current to power things like home appliances and common household appliances. In addition, it can be used for powering solenoids, valves, actuators, signal lights, meters, and motors. It is also used extensively in safety systems, where it can be used to trigger alarms in the event of system failure or other emergent situations.

Working Principle

The H12D48125-10 is a semiconductor switching device. It is normally in the off state, allowing no current to flow. When a current is applied to the control terminal, the relay closes internally and electricity can then flow from the AC input connector to the output connector. When the current is removed from the control terminal, the relay opens, preventing electricity from flowing. This “open-close” electrical operation occurs each time the control terminal is energized and extinguished, making it ideal for controlling applications that cannot necessarily be addressed by across-the-line operation.

The internal components of the H12D48125-10 are designed to ensure safety and reliability. An input-output insulation of 4.2kV AC makes it suitable for use in environments that require a medium-level of safety. In addition, its fast switching technology (50Hz-60Hz) helps reduce heat loss and improve efficiency, meaning it’s well suited for energy-saving applications.

Various forms of current-limiting and thermal protection are also integrated into the H12D48125-10, helping to protect it from damage caused by an overload of current or high-temperatures. All of these protective features combine to make the H12D48125-10 an ideal Solid State Relay for a wide range of applications.
