PV75L14-5PY (hereinafter referred to as the "PV") is a light powered, high efficiency, high reliability solid state relay suitable for a variety of applications. It has a wide range of voltage input (2-12V), wide temperature range (-20°C to 85°C), low current consumption, fast switching speed and a wide range of output current ratings (0.25A to 5A).The PV has a wide range of application fields and different working principles.

Application Field

The PV is mainly used in lighting control systems, home automation systems, industrial equipment, HVAC systems, access control systems, motor control systems, external interface devices, and other electronic control systems. It is also suitable for high temperature, low temperature, and ultra-hot environments. As a solid state relay, the PV can handle more types of load than traditional mechanical relays, such as four-pole contactors, SOLENOID valves, small lamps, and motors. It enables precise and reliable switching of various types of loads.

Working Principle

The internal components of the PV are mainly: light-emitting diode (LED), MOSFET, photodiode, and some other components. When an appropriate forward voltage is applied to the LED, current will flow, producing light in the corresponding wavelength. The photodiode receives this light and produces an electric signal output. The MOSFET acts as the switch in the circuit, and the output current is controlled by the resulting signal. Thus, the control side and the load side are insulated from each other, forming a completely closed loop control system. Due to the low power consumption and fast switching, the PV can achieve a high degree of accuracy and reliability.

Conclusion

The PV is a high efficiency, high reliability solid state relay suitable for a variety of applications. It has a wide voltage range, wide temperature range, low current consumption and fast switching speed. As a result, it can efficiently control various types of loads accurate and reliably.
