SP-48DC10 is 48V Din-rail Surge Protector. It uses a multi-stage discharge tube and fuse device to effectively suppress and release surge currents in low-voltage circuits.
The module includes a fuse protection device that allows fast (ns-level) discharge to the ground during surge events. If the surge current exceeds the limit, the fuse disconnects from the ground to prevent further damage. If a fault or damage occurs, maintenance personnel can quickly inspect and replace the module.
1. Multi-Stage Surge Protection – Effectively reduces and discharges surge currents in low-voltage circuits.
2. Fast Surge Discharge – ns-level response time ensures quick grounding of excess voltage.
3. Automatic Fuse Protection – Disconnects from the ground when surge exceeds the limit, preventing secondary damage.
4. Easy Maintenance – Faulty or damaged modules can be quickly inspected and replaced.
5. Standard 35mm DIN Rail Mounting – Supports quick and secure installation.
6. Flame-Retardant Plastic Housing – Lightweight, durable, and designed for safety.
7. Strong Surge Endurance – Can withstand multiple surge impacts with proper grounding.
The low-voltage surge protector module is installed in series and widely used in weak current systems such as security surveillance, telecommunications, data centers, transportation networks, and industrial automation.
Suitable for low-voltage devices including cameras, alarms, intercoms, sensors, and mini computers.
