Application Fields

The AHK22124 is suitable for a wide variety of Power switching applications. It is ideal for solar inverter applications, industrial applications, and consumer electronic applications. It is also suitable for Power Conversion and supply/demand balancing in energy-grid applications.

Working Principle

The AHK22124 uses two sets of contacts, one for current controlling and one for current measurement. The current-measurement circuitry measures the current, and the current-control circuitry is used to activate the relay, when the current exceeds a preset value. The two contacts are connected in series via a diode bridge, so that the relay is triggered when the current passes through the diode bridge. The Pulse-on-off functionality is provided by a built-in relay, which is triggered by the current-measurement contacts and deactivated by the current-control circuitry.

Conclusion

The AHK22124 is a highly versatile two-pole power relay, with a current rating up to 2 Amps. It is suitable for a wide variety of applications in many different industries, including solar inverter applications, industrial applications, and consumer electronic applications. It has a built-in overload protection circuit, and an integrated current-measurement unit and current-control unit. The Pulse-on-off functionality makes it suitable for precise control of the switching current.
