DC Power SPD
DC surge protective device, also called dc lightning arrestor or dc surge suppressor, is designed for the protection of DC power circuit from the damage of lightning overvoltage, induce over-voltage, transient operation, and resonance (Less than 100μs) overvoltage. Besides low voltage 12v, 24vdc surge suppressor, high voltage dc spd 600v, spd 1000vdc are also available. For the price or other information of spd for power supply, please feel free to contact us.
