Reliable Surge Protection for 48VDC Power Systems
The SP-48DC10 is a compact DIN-rail mounted surge protector designed specifically for 48VDC circuits. Built with a multi-stage protection design, it quickly suppresses transient overvoltage events such as lightning strikes, ensuring the safety and reliability of critical telecom, industrial, and automation equipment.
·Fast Response and Stable Protection
Engineered for low-voltage DC applications, the SP-48DC10 reacts in nanoseconds, diverting harmful surge energy to ground before it can damage connected devices. Its robust construction allows it to withstand repeated surge events, providing long-term reliability for sensitive DC-powered systems.
·Compact, Modular, and Easy to Install
The modular structure makes inspection and replacement simple, minimizing downtime during maintenance. Designed for standard 35mm DIN-rail mounting, it integrates seamlessly into DC distribution panels, telecom racks, or control cabinets. The flame-retardant housing enhances safety and ensures consistent performance in demanding environments.
