surge protection device spd

SLV-10S/SLV-20S is a compact ultra-low residual voltage surge protection device designed for single-phase power supply systems, ideal for fine lightning protection in LPZ 1-2 and subsequent lightning protection zones. As a series-installed fine arrester at the front end of equipment, it integrates full-mode protection to shield against surges in line-neutral, line-earth, and neutral-earth paths.Equipped with LED status indication (green: normal; red: failed) and open-circuit

LPF Series is a specialized surge protector designed for LED street lights, sensors, and other outdoor equipment, suitable for installation in LPZ 2-3 and subsequent lightning protection zones. It adopts a one-port full-mode protection design, providing comprehensive shielding against surges in line-neutral, line-earth, and neutral-earth paths. Featuring small size (42mmx30mmx23mm) and easy installation, the product is ideal for space-constrained outdoor applications. The

LS-P Series is a T2+T3 level power surge protection device designed for final-level equipment lightning protection in AC and DC power systems, suitable for installation in LPZ 2-3 and subsequent lightning protection zones. As a series-installed fine arrester at the front end of equipment, it provides targeted protection for sensitive electronics and precision devices.Featuring two ports and full-mode protection, the product offers comprehensive shielding against surges in

Product Description Induced lightning surges and grid switching transients often burn industrial mainboards, inverters and building low-voltage hardware. This 4-pole three-phase SPD acts as secondary protection in LPZ0B-LPZ1 cabinets, conducting and diverting surge currents within 25ns to clamp residual voltage to safe ranges and reduce overvoltage breakdown risks for downstream electronics. 40kA maximum discharge capacity withstands repeated heavy lightning impulses; anti

Product Description Laboratory precision measuring instruments are highly sensitive to voltage fluctuations and lightning surges; transient high voltage causes sensor calibration drift and permanent circuit damage. This 4-pole Type 2 SPD is installed on lab three-phase incoming distribution panels. The low voltage variant delivers residual voltage as low as ≤ 1.25kV with ≤ 25ns nanosecond-level response to divert surge currents and contain impulse voltage within instrument

Product Description Three-phase auxiliary distribution cabinets inside EV charging stations are vulnerable to lightning induced surges and grid switching impulses, which cause charger mainboard and metering module breakdowns and downtime. This 4-pole Type 2 SPD is mounted in LPZ0B-LPZ1 secondary panels within charging stations, diverting lightning transient currents with 40kA surge capacity and clamping residual voltage within safe limits via ≤ 25ns fast response to protect

Product Description Conventional SPDs without remote contacts rely entirely on manual inspection; degraded failed modules operate undetected and leave downstream equipment unprotected. This 4-pole surge protection device integrates NC/NO switching remote contacts to send automatic switch alarm signals to automation monitoring platforms upon SPD failure, paired with front visual status window for on-site check, delivering dual local & remote monitoring.
