Description

AC DC SPD Type 2 is a surge protection device designed to protect electrical systems from transient overvoltages caused by lightning strikes or other electrical disturbances. For the brand "Infi" and its Type 2 SPD, here’s a general outline of what you might expect: Key Features of Infi AC DC SPD Type 2: Type 2 Classification: Type 2 SPDs are suitable for installation at the distribution board and are designed to handle lower energy surges that occur after a Type 1 SPD (if installed upstream) has intercepted the initial high-energy surge. AC and DC Protection: This SPD provides protection for both AC (Alternating Current) and DC (Direct Current) systems. This is crucial for systems that may include both types of electrical currents. Voltage Rating: Ensure the SPD is rated for the operating voltage of your system. For AC systems, this might typically be 230V or 400V, while for DC, it could vary depending on the application. Discharge Current Capacity: This rating indicates the SPD's ability to handle surge currents. Look for the rated discharge current (Imax) and the impulse current (Iimp) to ensure it matches your system's needs. Protection Level (Up): This is the residual voltage the SPD will allow to pass through to your equipment during a surge. Lower values indicate better protection. Mounting: SPDs can be mounted on DIN rails, which is standard for many distribution panels. Check compatibility with your panel setup. Indicators and Status Monitoring: Some models feature visual indicators or remote monitoring capabilities to show the status of the SPD and whether it needs replacing. Compliance and Certification: Ensure the SPD complies with relevant standards such as IEC 61643 or UL 1449, which can vary depending on your location and application. For specific technical details and installation instructions, consult the product manual or technical datasheet from Infi or the distributor.
