Raycap Inc. has developed a surge protection device (SPD) that provides continuous protection from over-voltage and other transient voltage activity for industrial equipment such as variable speed drives (VSDs), programmable logic controls (PLCs) and power cabinets. Designated Strikesorb, the SPD modules are designed to protect equipment from lightning strikes, power surges, and spikes without performance deterioration. Strikesorb modules are available in a wide range of voltage and packaging configurations to protect sensitive equipment and electronics. Strikesorb modules meet the demanding requirements of IEC 61643-1 and UL 1449 2nd Edition (Dated February 7, 2007) without the use of internal fuses.
