AQV214H is a type of Solid State Relays (SSRs) which are also known as electronic relays. They are a reliable, affordable, and capable alternative to traditional electromechanical relays. The AQV214H series SSR is a 4-pin type of SSR with zero voltage turning. It is suitable for both AC and DC loads and offers an efficient way to switch current up to 67A without the shaking and noise of an electromechanical relay. The AQV214H series is highly reliable and offers low-cost compared to other models on the market.

The AQV214H is constructed of four elements; a power module, control module, heating element, and a heat sink. The control module contains a proven industrial-grade thyristor with built in protection against both over-current and over-voltage. The heating element is a non-contact solid state ceramic resistor which provides rapid switching of the thyristor at precise temperatures. The heat sink is a solid aluminum or extruded aluminum hosing designed to dissipate the heat from the heat element. All of these components work together to create a reliable, efficient switching solution.

The AQV214H series is designed to operate in two basic modes. The zero-voltage turning (ZVT) mode uses a high trigger current to instantly switch the thyristor without the need for any external devices. This mode is suitable for use with AC loads. The other is the zero-crossing turning (ZCT) mode, which uses a low trigger current to switch the thyristor when the voltage line crosses from positive to negative. This type of switching is better suited for DC loads.

The AQV214H series is also designed with many other benefits. One of these is a PCB mounted relay option which allows the AQV214H to be directly connected to the PCB for a clean and efficient installation. It also has an extended wiring distance and integrated mounting brackets for easy installation. The AQV214H also offers two levels of protection from both short-circuit and overloads with an adjustable cool-off time.

The AQV214H series SSR is a great choice for applications where a reliable, low-cost, and efficient switching solution is needed. Typically it is used in consumer and industrial applications such as lighting control, home automation, motor speed control, and temperature control. The AQV214H is also ideal for applications which require frequent switching, long-term operation, and an efficient way to control current.
