Frequently Asked Questions

Q1 What is the primary application of this 500VDC Surge Protective Device (SPD)?
This SPD is specifically engineered to protect medium voltage DC systems, including solar photovoltaic installations, industrial automation systems, and energy storage setups, against transient overvoltages and lightning-induced surges.
Q2 What does the 2P configuration mean for installation?
The 2P (two-pole) configuration provides dedicated protection for both the positive (+) and negative (-) lines of your DC system relative to the protective earth (PE), ensuring comprehensive safety coverage.
Q3 How does the visual status indicator work?
The device features a clear front-panel indicator. Green indicates the device is operating normally and providing full protection. When the indicator changes color (typically to red), it means the module has reached its end-of-life and must be replaced.
Q4 Is this surge protector easy to install on standard panels?
Yes, it features standard 35mm DIN rail mounting and secure screw terminal connections, making it extremely easy to integrate into standard industrial control panels and distribution boxes.
Q5 What safety standards does this device comply with?
This surge protective device fully complies with international safety and performance standards, specifically meeting the rigorous requirements of IEC 61643-11 and EN 61643-11.
Q6 What is the response time of this surge protector?
Equipped with premium metal oxide varistors (MOVs), the device reacts in less than 25 nanoseconds, rapidly clamping high-voltage surges before they can reach and damage your sensitive downstream equipment.
