ACData's DDC Series plug-in surge protector maximizes protection of "bullet-style" DC distribution panels, by shunting transients entering from the load side and preventing them from propagating back to the
power supply.

The DDC Series features bipolar silicon avalanche diode (SAD) protection. The DDC048 uses four fifteen-joule SADs (60 joules), and the DDC024 uses nine five-joule SADs (45 joules). The DDC Series plugs directly into distribution panels using spring terminals. LEDs and Form C contacts provide local and remote monitoring capabilities.
