Solid State Relays

The AQW612SZ is a solid state relay (SSR) that is designed to control high-power AC loads such as resistive, inductive, motor, transformer, compressor and etc. It is suitable for HVAC, industrial automation, packaged and refrigeration equipment, audio-video equipment, air conditioning systems, building automation systems, and other control equipment.

AQW612SZ is an AC-controlled SSR, which means that the input is an alternating current voltage. The input voltage is connected to the ZC terminal, and the output of the control is connected to the ZC terminal. The output of the SSR is connected to the load. The input has a voltage range of 6 to 220Vac, with a frequency range of 48 to 63Hz. The output has a voltage range of 6 to 280Vac, with a frequency range of 48 to 63Hz.

The AQW612SZ has a built-in zero cross function, which means that at the moment when the input voltage crosses zero when going from positive to negative or vice versa, the output of the SSR turns on or off. This feature allows the SSR to be used to control inductive and capacitive loads without causing damage to the SSR due to contact bouncing.

The AQW612SZ has two control modes: AC control and DC control. In AC control mode, the SSR works when the input voltage is in the active range, and in DC control mode, the SSR works when the input voltage is higher than the threshold voltage. The advantages of using a DC control mode are that it can be used when the input voltage is low or unstable, and that it reduces the contact bouncing caused by AC operation.

The AQW612SZ has a number of safety features, such as thermal-magnetic circuit protection, short-circuit protection, electromagnetic interference protection, overvoltage protection, and LED indicators for monitoring. It also has a built-in relayswitch for manual opening and closing of the switch.

In summary, the AQW612SZ is a reliable and robust solid state relay designed to control high-power AC loads. It has a wide input voltage range and two control modes, with a number of safety features to ensure reliable operation. They are commonly used in industrial automation and other control equipment, as well as in HVAC, audio-video, air conditioning, and building automation systems.
