Solid State Relays (SSRs) are devices that enable the control of an electrical power supply to an electrical load using a low power circuit that connects them. PF480D25 is a type of solid-state relay produced by E-T-A (Europe-USA Techniques Avancées). It is widely used in the Heating, Ventilation, Air Conditioning (HVAC) application as well as many industrial control applications.

Given the increased demand for energy efficiency and control, the PF480D25 is an ideal solution for applications that require precise control of AC voltage levels. It is designed to provide reliable voltage control that is both highly efficient and cost effective. The PF480D25 is an exceptional device as it is capable of delivering up to 25A of current, sufficient to power a wide range of loads, from light loads to large motors.

The working principle of the PF480D25 is based on switching a low power control signal on or off to control the supply of current to the load. The user application controls the low power control signal, which is connected to the PF480D25 via a switching control point. The power circuit of the PF480D25 then provides the main control of the AC voltage going into the load. The control signal provides a simple on/off voltage control that does not require complex analog controls.

The PF480D25 is a highly advanced device and offers several additional features such as: • Fast response and switching time, which allows for more precise control over the AC voltage • Soft-start/stop feature to minimize the surge current while the load is starting or stopping • Robust selection of operating temperature range, rated up to 70°C, meaning it can handle more demanding environments • Option for reverse polarity protection, providing an added layer of protection against faulty wiring and other accidents.

The PF480D25 is an ideal solution for users who need precise control of AC voltage levels, as it can provide fast, reliable switching within a wide range of temperatures and current ratings. It is also a highly reliable device and offers multiple features that make it extremely versatile. This makes it suitable for a range of industrial and HVAC applications that require precise control of AC voltage.
