With the improvement of technology, more and more people tend to use Solid State Relays products to meet their electrical needs. And AQV112KL belongs to this kind of products. AQV112KL have the advantages such as fewer components, and longer product life, and etc. It is widely used in industrial, commercial, residential, and military applications.

AQV112KL is a smart-type Solid State Relay product. It’s an all-in-one relay, that combines circuit protection, control and electrical rating into a single product. This product features a zero current-switching (ZCS) capability, which allows it to maintain optimal electrical characteristics even when switching currents of high-speed-changing signals. It is suitable for high-speed/high-power motor control applications in industry automation and process control. In addition, it has a wide temperature range and a tight tolerance on a wide range of input voltage and output current.

The working principle of AQV112KL is based on the current mirroring effect of MOSFETs. When the DC input voltage is applied to the galvanically isolated gate terminal, a small bias is created across the insulated gate. The positive voltage at the gate terminal will cause the MOSFET to turn ON and the resulting reverse current will be mirrored through the passive transformer to the second MOSFET. This provides a zero current-switching (ZCS) with a low source impedance, allowing for reliable operation even under high-speed operation.

AQV112KL is ideal for applications with a rapidly fluctuating load current, including industrial motor drives, traffic control systems, HVAC applications and industrial process controls, as well as switchgear and other temporary power transfer applications. It offers excellent EMC performance and safeguards against electrical interference due to high-switching frequencies. It also has a very low stand-by power consumption, which helps to reduce energy cost. Furthermore, it is designed to withstand high temperatures and humidity, making it suitable for use in harsh environmental conditions.

To summarize, AQV112KL is a high performance solid state relays which is widely used in industry automation, traffic control systems, HVAC applications, switchgear and other temporary power transfer applications. It has numerous advantages such as zero current switching, low standby power consumption, high accuracy, wide temperature range and high EMC performance. Therefore, AJV112KLis highly recommended for people who need a reliable and efficient solid state relays in their application.
