Designed to be compatible with a Maximum Continuous Operating Voltage (Ucpv) suitable for PV systems operating up to 600V DC nominal voltage.
Utilizes high-energy MOV technology to provide a low Voltage Protection Level (Up), so that the residual voltage doesn't affect downstream equipment during a surge event.
Specifically tested and certified to the standard IEC / EN 61643-31 for SPDs used in photovoltaic applications, ensuring proper protection for 600V DC solar circuits.
Features standard DIN rail mounting and pluggable modules, simplifying installation and easy replace the module in combiner boxes.
LETOP 600V DC surge protector range includes Type 2 and Type 1+2 devices designed for 600V system applications. Our 600V DC SPD with thermal disconnect has advanced safety features with clear status indication and fail-safe operation modes. Each device incorporates premium MOV chip with ultra-fast response time <25ns and minimal leakage current <50μA. Technical specifications include wide operating temperature range (-40°C to +85°C), IP20/IP65 enclosure options, and compliance with IEC 61643-31 standards.
