Surge Protection Device (SPD) for LED Lighting
Surge Protection Device for LED Street Lighting
LED Light is a voltage sensitive device and must be supplied with a voltage above its threshold voltage and a current below their rating. Its lifetime will be reduced dramatically even with a small change in applied voltage. In order to prevent failure or to extend its life time, the installation of proper surge protective device (SPD) against surge damage is highly recommended.
The low voltage surge protector WS3VT/390-10 is a compact surge protection device (SPD) especially for outdoor LED light and LED street light in lightning & surge protection. All mode protection circuit enables it used universally worldwide. VT technology is used to eliminate leakage current to ground (or protective conductor) to avoid malfunction of upstream residual current protection device.
Features
- Complied with IEC 61643-11 and UL 1449 4th
- Designed to protect single-phase LED light or other electrical and electronic facility
- Suitable for using in Un 110~347Vac single phase
- VT (GDT and MOV in series) technology to eliminate leakage current. And provide better reliability and robustness & TOV(temporary over-voltage) withstand performance
- Max Discharge Current up to 10kA 8/20us and Open Circuit Voltage Uoc to 20kV
- Offering full mode protection to L-PE, L-N, N-PE
- IP67 waterproof enclosure
