Solid State Relays (SSRs) are unique components designed to control electrical power. They can be used to control both AC and DC loads, while offering greater protection from surge currents, and superior reliability and durability compared to traditional electromechanical relays. The D2D12K solid state relay is an AC load controller known for its sleek design and flexibility. It was designed to provide maximum performance while eliminating the need for slow and unreliable mechanical relays.

The D2D12K SSR is a two-stage load controller with a 12 Amp rated load. It is a UL Recognized Component, providing users with peace of mind as they use it in various applications. The D2D12K features an auxiliary contact that is adjustable down to 1/2 Amp, enabling the system to function as a one or two-stage controller. This allows for better system optimization and efficient control.

The primary application of the D2D12K is to switch line voltages up to 250 VAC @ 50 Hz. It is ideal for industrial applications, such as industrial lighting, heating, air conditioning, refrigeration systems, and many other applications where a high-current SSR is required. Additionally, the D2D12K can also be used in low-voltage AC/DC applications. It is also suitable for a variety of impulse and electronic power switching.

The D2D12K is equipped with a built-in LED power input indicator and adjustable overload protection. The overload protection can be adjusted to 120%-130% of the rated current, ensuring reliable operation and long-term reliability. It has a temperature range of -20 to +85°C (-4 to 185°F). The D2D12K is also equipped with two AC input terminals and two AC output terminals and features a 12A rated load.

The working principle behind the D2D12K SSR is simple. The device works on the principle of transformers. It makes use of the inductive and capacitive reactance of a transformer to control the current flow. The current is applied to the primary coil, which induces an alternating magnetic field. This field in turn induces a secondary voltage on the secondary coil, which causes a switching of the alternating current.

The current flow can be regulated by varying the amount of current applied to the primary coil. The amount of current applied is controlled by the internal circuitry, which in turn is controlled by the user-set parameters. The device also features a fast response time, which is important for applications with strict time requirements. Furthermore, the device is hot-swappable, meaning that it can be safely and reliably stopped or started in the middle of an operation.

To summarize, the D2D12K SSR is an excellent device for applications requiring both AC and DC load control. It is a reliable and durable device with an adjustable overload protection, LED power input indicator, hot swappable capability, and a fast response time. It is ideal for a variety of industrial and impulse applications. The working principle behind the device is based on the inductive and capacitive reactance of a transformer, which allows for precise and accurate current regulation.
