Introduction

Solid State Relays (SSRs) have been the choice for switching highly sensitive and precise electronic loads in many industrial and commercial applications. The AQY410EHA is a SSR that has been developed to provide continuous reliabilty and precise switching of loads with minimal influence on the circuitry. It is one of the most versatile and robust SSRs on the market due to its cutting-edge, high-voltage switching capabilities and can be used in a variety of applications.

AQY410EHA Application Field

The AQY410EHA is particularly well-suited for control, protection, and power-control applications in a wide range of environments. It is ideal for applications requiring high AC and DC isolation, low control power, and high output power delivery. Typical applications for the AQY410EHA include motor and solenoid control, inrush current control, switching of reactive and resistive loads, and logic/power gating. Its integrated current balancing features make it ideal for use in motor control circuits and other applications requiring precise current balancing.

AQY410EHA Working Principle

The AQY410EHA utilizes an insulated gate bipolar transistor (IGBT) as its main switching element. This advanced technology provides superior performance characteristics, allowing the AQY410EHA relay to switch loads up to 400A with a maximum switching frequency of 1kHz and control power of 5 watts. The AQY410EHA relies on a different operating principle than traditional mechanical relays. Instead of using physical contacts to close and open the switching circuit, the AQY410EHA utilizes an input voltage (typically 5V DC) to turn the IGBT on and off, thus providing more efficient current switching. In most applications, the AQY410EHA is configured to open the control circuit when the input voltage is high, and close the control circuit when the input voltage is low. The AQY410EHA features multiple control options, including S-R (Latch, Reset and Momentary) and C ( Off/On Toggle) type control inputs. The C-Type control option can be used to easily configure the AQY410EHA relay as a manual switch when used with an external switch.

Conclusion

The AQY410EHA is a versatile and robust SSR, capable of switching up to 400A, with a maximum switching frequency of 1kHz and control power of 5 watts. It can be used in a variety of applications, including motor and solenoid control, inrush current control, switching of reactive and resistive loads, and logic/power gating. Its integrated current balancing features make it ideal for use in motor control circuits and other applications requiring precise current balancing. The AQY410EHA achieves these capabilities thanks to its cutting-edge IGBT switching technology, providing more efficient current switching than traditional mechanical relays.
