Solid State Relays are commonly used to control the switching of a power source by using a low power control signal. The AQV414EHAZ is a type of solid state relay that is designed to provide a means of control over a given power source, without the traditional risks associated with mechanical relays, such as spark and wear. This device is also capable of delivering quite large currents when activated, making it suitable for a wide variety of applications.

External Design

The AQV414EHAZ is designed as a black plastic module with its power control terminals on the top side and its low current control terminals located on the other side. The module is designed to be installed on a flat surface for direct mounting. The black plastic casing provides good thermal insulation, which is important for short-circuit prevention. The terminals have an insulation distance of 8.0 mm to prevent electric shock and burn.

Control Method

The AQV414EHAZ uses a combination of discrete components and an integrated circuit in order to control the switching of an electrical load. The integrated circuit functions as a digital logic gate and is capable of detecting the control signal applied to its low current terminals. When a signal is present it will cause the integrated circuit to switch, turning on or off the power control terminals of the device. This allows the device to be used like a traditional on/off switch.

Power Ratings

The AQV414EHAZ has a rated operating voltage of 400 VAC, a rated operating current of 7.0 A and a Rated Operating Power of 2400 W. Furthermore, the dielectric strength between the control terminals and the power terminals is provided at 2500 VAC. This is required in order to prevent the flow of an uncontrolled current between the two terminals.

Applications

The AQV414EHAZ is suitable for a wide variety of applications, including motor control, heater control, light dimming and temperature control. In addition, it can be used to create a hardwired system that would otherwise use mechanical relays, allowing for greater reliability and reduced risk of failure. This makes it well suited for industrial settings, where it is often used as an alternative to a more expensive and complex system.

Conclusion

The AQV414EHAZ is a solid state relay that is capable of handling large currents while being relatively inexpensive. It is suitable for a wide variety of applications and can be used as a replacement for mechanical relays in many cases, providing a more reliable and cost effective system. This makes the AQV414EHAZ a popular choice for industrial and commercial applications.
