The Egis Mobile Electric 8810-1300B XD Series Flex 2 is a 500 amp bi-stable relay that can be programmed as an automatic charging relay (ACR) or a remote-controlled relay. As an ACR it combines two batteries for charging and isolates them when no charge source is present, eliminating dead start batteries without any user input.
Two independent start/engine isolation inputs let it manage multi-engine boats and vehicles with independent charge systems, isolating charge sources when both are active for best charging performance. The bi-stable solenoid holds its state without coil current, drawing just 1.3 mA when off – 90–95% less than competing solutions – while the front-facing 3-position knob gives clear manual control. A 6-pin Deutsch DTM connector provides plug-and-play, sealed control wiring.
Key Features:
- Programmable as ACR or remote relay via DIP switches under the cover
