ADSx Series — Surge Protection Device

DynaShield ® ADSx Surge Suppression

DynaShield ® ADSx series hardwired AC surge protection devices (SPDs) are fast responding devices designed to offer superior voltage protection levels at high surge currents. The SPDs are Listed to UL / cUL 1449 4th Edition Type 1 and Type 2 and are offered with surge current ratings of 50 kA, 100 kA, 200 kA and 300 kA to meet the most demanding protection requirements. These SPDs meet UL96A Lightning Protection Master Label requirements (@ 20 kAIn).

Diagnostics include easy-to-see status LEDs and dry contacts for remote annunciation. ADSx models are Type 2 cUL listed and provide complimentary UL 1283 Listed frequency reactive circuitry (FRC) to attenuate EMI/RFI noise up to -50 dB @ 100k Hz. Standard polycarbonate NEMA 4X enclosure allows for outdoor or indoor installation. Ruggedized enclosures are available in NEMA 4 painted steel or NEMA 4X stainless steel.

DynaShield Applications

ALLTEC’s Protection Pyramid depends on DynaShield® products to support its comprehensive facility framework. The second tier of protection diminishes the significance of random high-energy, short-duration electrical power transients through properly installed surge protective devices. These occurrences are typically caused by atmospheric phenomena (such as lightning strikes), utility switching, inductive loads, and internally generated overvoltages. You can view typical installation locations in the application maps to the right by locating the numbers 5 and 6.
