Solid State Relays

Solid state relays (SSRs) are electrically operated switches used to regulate power to an electrical load without using traditional electromagnetic relays, which are powered by mechanical components such as coils and contact arms. SSRs use semiconductor switching elements, such as transistors or thyristors, to control power. SSRs have a variety of uses in commercial, industrial, and other applications.The AQV204A solid state relay is a 4-channel 8A AC SSR. It is designed with a very small size and a stable, reliable switching performance. The AQV204A is suitable for multiple switching applications such as motor control, lighting control, temperature control, heating and cooling systems, and various other industrial control applications.

AQV204A Application Field and Working Principle

The AQV204A is a 4-channel 8A AC SSR with a load current up to 8A and an input voltage of 100 to 240V AC. It is suitable for controlling AC loads such as motors, lighting, heating and cooling systems, and other industrial control applications. The AQV204A is designed with a built-in zero-crossing detector for better noise suppression and protection against over-voltage or over-current events. The working principle of the AQV204A is simple. When a small current is applied to the control terminal, it activates the internal solid state switching element, which then sends an electrical signal to the output terminals. This signal then turns on the connected load. When the small signal is removed, the load is turned off. The AQV204A is designed to ensure that the AC waveform on the output is very close to the waveform on the input, with no significant loss of power. The AQV204A features a very small size and a built-in zero-crossing detector to ensure high noise immunity and circuit protection against over-voltage/over-current events. The AQV204A is designed with a dielectric insulation of up to 4.5kV to ensure safe operation and a long-term reliability. Furthermore, the AQV204A is built with an efficient heat dissipation system in order to keep its operating temperature low and maximize its lifetime.The AQV204A is suitable for a wide range of applications, including motor control, lighting, temperature control, heating and cooling systems, and various other industrial control applications. It is also well-suited for high-frequency switching applications since the switching time is only a few milliseconds. Additionally, the AQV204A is compatible with a variety of external control signals, including ON/OFF, PWM, and others. Furthermore, it can be easily interfaced with a variety of controllers through the use of a corresponding driver. In conclusion, the AQV204A is a reliable and economical 4-channel 8A AC SSR designed for multi-purpose applications. Its small size and efficient heat dissipation system make it suitable for a variety of applications, and its built-in zero-crossing detector and dielectric insulation provide a safe and reliable operation. Additionally, its wide compatibility with external control signals and controllers makes it an ideal choice for various industrial control applications.
