Egis Mobile Electric 8520-1350 XD Dual Flex L VSR/Relay Automatic Charging Relay with Knobs

The Egis Mobile Electric 8520-1350 XD Dual Flex L is a dual-position bi-stable automatic charging relay (ACR/VSR) with manual override knobs, engineered for modern marine, RV, and powersports electrical systems. This compact module consolidates two individual high-amp relays into a single unit, eliminating external link cable connections and the risk of vibration-related failures — all while dramatically reducing panel space requirements.

Each relay position is independently configurable as either a Voltage Sensing Relay (VSR) or a standard remote relay via on-board dip switches, giving OEMs and installers significant flexibility without custom wiring. The unit is fully Lithium Battery System Ready, supporting the higher ON/OFF charge voltage thresholds required by LiFePO4 and other lithium chemistries beyond legacy lead-acid settings.

Key Features:

• Dual VSR/Relay Configuration — Each position independently programmable as a VSR or remote relay via simple dip switches
• Lithium Battery Ready — Supports higher charge/discharge voltage settings required by modern lithium battery chemistries
• 3-Position Manual Override Knobs — Force each relay open or closed; leave knob in position to lock relay state
• Front-Facing LED Status Display — Instant visual feedback of device state; remote LED replicates local indicator
• IP67 / IP6K9K Sealed Construction — High-temperature electronics and materials rated for harsh environments; mountable anywhere
• 35–75% Space & Weight Reduction — Advanced bi-stable solenoid design replaces multiple discrete components
• 90–95% Less Off-State Current Draw — Compared to competitive multi-device system solutions
• Plug-and-Play Legacy Compatibility — DTM/ATM connectors are pin-for-pin compatible with ML Series Bi-stable Relays
• Stainless Steel Hardware — Corrosion-resistant studs and self-locking flanged nuts for long-term reliability
• Integrated Gortex Vent — Regulates internal pressure to prevent moisture ingress across seals
• Protective Cover Included — Guards terminal studs and cable edges against inadvertent shorts
• 40-Circuit Weatherproof Label Sheet Included — Pre-printed and blank labels with convenient panel recesses for easy identification
• Large Mounting Holes — Accept 1/4-20 or M6 attachment hardware

The 8520-1350 is an ideal solution for dual-battery charge sharing, battery isolation, and load switching in marine, RV, commercial vehicle, and off-road applications. Its compact, all-in-one design and broad programmability make it a top choice for professional installers and OEM integrations alike.
