DIN-rail mounted DC power Surge protective device(SPD)

Name: DIN-rail mounted DC power Surge protective device(SPD)
Brand: Shenzhen Techwin Lightning Technologies Co., Ltd.

DC power SPD, 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, 24v DC surge protection devices, high voltage 600v, 1000v solar DC surge suppressors are also available. For the DC SPD price or other products of spd for power supply, such as ac spd, please feel free to contact us.
