Let You Know About Dc Surge Protector, You Will Regret It If You Don't Read It
At present, DC surge protectors are widely used. Their working principle is the same as that of AC surge protective device, which discharge the surge of instantaneous overvoltage generated by lightning. However, due to the low voltage resistance of DC equipment components, if interference is caused by surges, huge losses will occur. Let us get to know the DC surge protection device.
1. Configuration requirements of DC surge protectors
1. T1 or T2 SPD
2. DC voltage range: 12Vdcz to 1500Vdc
3. Pluggable
4. Single-mode or dual-mode configuration
5. Safety tripping and remote signal alarm
2. Application scenarios of DC surge protectors
1. 800~1500V DC power supply for energy storage system
2. 380/400V DC power supply for data/telecom center
3. Power Electric vehicle charging pile 400V + DC power supply
4. Off-grid photovoltaic power station 24~130V DC power supply
5. Telecommunication system 48V DC power supply
III. Selection of DC surge protector
Warm reminder: Special attention should be paid to the short circuit of the DC power supply line. Its rated short-circuit current value varies from low (controlled DC power supply) to high (battery system) according to the size of the system. The relevant parameters of SPD (Lsccr value) must be greater than the expected short-circuit current of the DC power supply system.
