Solid State Relays

Solid State Relays (SSRs) are electronic control systems that are used in place of traditional electromechanical relays and contactors. They are electronic switching devices that allow their user to remotely control an application\'s power input with a low input voltage. The AQV215AX is one of the many models of SSRs that are designed to provide a reliable, efficient, and cost-effective solution for industrial and commercial applications that require a high level of power control.

The AQV215AX is a high power, two-circuit SSR with a maximum switching capacity of 30A, 220VAC. It has a unique two-circuit design that allows it to operate with either single-phase or three-phase power. It also features a wide range of input and output voltage options, including 10-220VAC, and is compatible with PLC/SCADA systems, making it an ideal choice for industrial applications.

One of the primary applications of the AQV215AX is as a motor starter for AC induction motors. It can be used to switch on and off an electric motor from a distance, which, in turn, enables energy savings and flexible motor control. It can also be used in other applications that require a high switching capacity, such as in HVAC control systems, lighting controls, and fire alarm systems.

Working Principle

The AQV215AX uses a thyristor-based switching system to enable its remote control functionality. In this system, the thyristor acts as a switch between the two output terminals. When the control input voltage is applied, the thyristor turns on, completing the circuit between the two output terminals and allowing the current to flow. When the input voltage is removed, the thyristor turns off, interrupting the flow of current.

The AQV215AX\'s unique two-circuit design allows it to switch both single-phase and three-phase power. When switching single-phase power, two thyristors are used to control the output voltage. When switching three-phase power, three thyristors are used, in a bridging configuration, to divert the current into the motor. This configuration allows the AQV215AX to switch both high and low power ratings, making it ideal for a wide range of industrial and commercial applications.
