Solid State Relays (SSRs) are a type of switch that uses a low voltage or current electronic signal to turn a high voltage or current electronic signal on or off. They are commonly used in the home automation industry and allow a user to switch a load, such as a light or motor, on or off without the need for a physical switch.

The HDC100A120 is a Solid State Relay with a maximum current rating of 100A and a maximum voltage rating of 120V. This relay is typically used in large industrial applications such as transformers, motors, or generators. Its primary application fields are power engineering, industrial automation, and precision machine control.

The working principle of the HDC100A120 is based on the MOSFET technology, which stands for "metal oxide semiconductor field effect transistor". This type of transistor is used to control current flow in an electrical circuit. The MOSFET allows for a low-level "gate" voltage to control the flow of a high-level current between the source and the drain, without any physical switch. In the case of the HDC100A120, an input voltage of 5-12V DC is applied to the gate which then turns on the relay and allows current to flow between the source and the drain.

The HDC100A120 is a great option for anyone looking for a reliable, high-current Solid State Relay with a reasonably low input voltage. Its wide application fields make it a great choice for industrial applications, and its MOSFET technology ensures that the relay will perform reliably and accurately in a range of different electrical circuits.
