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 ...
• Voltage: The voltage continuously applied between the SPD terminals does not exceed the maximum continuous working voltage Uc
• The altitude should not exceed 2000m
• Ambient air chlorine temperature: normal range -5°C~+40°C, extreme range -40°C~+85°C.
• Relative humidity: should be between 30% and 90% at room temperature
• The SPD adopts 35mm standard guide rail to install the product in the distribution cabinet or box of the distribution box.
• The connecting line should be as short as possible, and the total length should be less than 0.5m
