What is a DC Surge Protective Device？
DC Surge Protective Devices (SPD) are essential for safeguarding electronic systems from voltage spikes, ensuring both reliability and efficiency. Their ability to absorb and redirect excess voltage helps ...
• Usage: Low Voltage, Solar PV
• Safety Standards: IEC•Type: Thermal DC fuse
• Certification:TVU、CE、IEC
