ElectronicsThe DP3500SB with Discharge Tubes (GDT/TSS) SMB RoHS manufactured by Dongchen Electronics is a device designed to protect surge current in power supply systems and field controllers. It features a GDT/TSS (Gas Discharge Tube/Thermal Surge Suppressor) with RoHS (Restriction of hazardous substances) compliance. This surge protector offers overvoltage and overcurrent protection and features a single MOV (metal oxide varistor) energized bypass switch, allowing for a straightforward and safe switchover to a secured DC voltage source. It is designed for protection against high voltage transients and other power anomalies. Additionally, it is able to withstand high surge currents of up to 7000A, making it suitable for high-load applications. This device also features SMB RoHS up to three times higher operational voltage than similar surge protectors. It is a compact and reliable solution for protecting and supplying surge voltage.
