panel surge protective device (panel SPD) - PS series

PS Series Surge Panel (900kA max.)

PS Series – Panel Surge Protection Device (Panel SPD)

Prosurge PS series panel surge protection devices are ultra-large surge capacity design for mission-critical application with very high exposure to lightning. They are UL 1449 5th Type 1 / Type 2 tested for point-of-entry (Category C, D, E, IEEE C62.41) and sub-circuit (Category B) protection. With surge capacity up to 900kA, PS series surge panel can meet most critical surge protection challenges worldwide and ensure maintenance-free for its lifetime.

By employing Prosurge’s patented SMTMOV/HSMTMOV, a thermally protected and arc extinguishing technology component, PS series has a significant advantage in abnormal over-voltage & high fault current safety and thus ensure industry’s highest level of safety and performance. The parallel redundancy modules design makes PS series more robust and reliable.

Anticipatory Failure Monitoring Technology

The Anticipatory Failure Monitoring (AFM) technology allows users to replace SPD before the protected electrical equipment or systems are threatened by overloads and thus ensure uninterrupted surge protection. Three stages LED indication (Blue-Yellow-Red) can help users to understand the current protection status. When the blue LED indicator turns to yellow, it shows that the SPD is in potential failure status and a replacement of the SPD is recommended. If the SPD is not replaced, it still continue to provide limited protection yet further overloads may lead to the risk of surge damage.
