The Egis Mobile Electric XD Flex 2 Dual VSR/Relay (8720-1350) is a compact, high-performance dual bi-stable relay module designed for demanding marine, RV, and vehicle electrical systems. Each relay delivers 500 amps of continuous current capacity and up to 1,500 amps of max cranking current, all within an extremely compact footprint that replaces two individual high-amp relays in a single sealed module.
Configured via simple onboard dip switches, each relay position can be independently programmed to operate as a battery disconnect switch, an automatic voltage sensing relay (VSR/ACR), or a low voltage disconnect (LVD) — giving installers and OEMs exceptional flexibility in a single device. This unit includes front-facing manual override knobs that allow each relay to be locked ON or OFF for servicing, with clear visual indication of the override state.
Remote ON/OFF/Auto inputs allow each relay to be forced closed or open, or to operate automatically based on voltage sensing. Onboard and remote LED indicators per relay provide at-a-glance status and diagnostic feedback. The ultra-low off-state current draw of just 1.3 mA is among the lowest in the industry, making it ideal for always-connected installations.
Built for harsh environments, the XD Flex 2 is sealed to IP67/IP6K9K standards with a high-quality Gore-Tex vent to regulate internal pressure and prevent moisture ingress. Corrosion-resistant stainless steel cable lug studs and self-locking hardware ensure long-term reliability. This version includes pre-tinned wire leads for straightforward installation and is compatible with Deutsch DTM/ATM connector pin assignments for legacy system integration.
