CITEL - DS2x0-xxDC - DC Surge Protection
The DS2x0-xxDC surge protector is designed to protect equipment connected to a DC power supply (or AC) against lightning surges. These devices are based on high energy varistors (MOV) matched with the DC operating voltage (from 12 to 350 Vdc). The MOV are equipped with internal thermal disconnectors in order to provide safe end of life. The indication of the disconnection status is provided by a mechanical indicator and is transmitted through a remote signal mechanism. The pluggable module... (read more)

Surge Protection Excerpts from IEEE Standard 1100-2005. The Emerald Book: IEEE Recommended Practice for Powering and Grounding Electronic Equipment (.pdf)
Nature of lightning strike damage: "...many types of electronic circuits can be damaged or. destroyed when exposed to an excess current or an excess voltage produced by that current. If lightning strikes on or near overhead electric power or telephone line, a large current will be. injected
