FAQ
Q1: What is the load current capacity of SLV 220-10/SLV 220-20?
A1: The maximum load current is 5A, suitable for low-power sensitive equipment and electronics.
Q2: Can it be used for DC power systems?
A2: No, this model is specifically designed for AC 220Vac systems. For DC applications, choose dedicated DC SPD models.
Q3: What is the difference between SLV 220-10 and SLV 220-20?
A3: The core difference is discharge current: SLV 220-10 has In=5kA/Imax=10kA, while SLV 220-20 has In=10kA/Imax=20kA.
Q4: Is the product compatible with smart home systems?
A4: Yes, its compact size and low leakage current make it suitable for integration into smart home control systems.
Q5: How to test if the SPD is working normally?
A5: Use a surge generator to simulate transient overvoltage; if the SPD diverts the surge current and limits the voltage to the specified level, it is working normally. Regular visual inspection of the product (no physical damage) is also recommended.
