Swift Kompany 8720-1390 Dual XD Flex 2 ACR/Mechanical Switch with Knobs

The Swift Kompany 8720-1390 is a dual XD Flex 2 battery switch and automatic charging relay (ACR, also called a voltage sensitive relay or VSR) with mechanical switching. It combines two high-amp relay positions in one compact, sealed module. This simplifies wiring for dual-battery and multi-battery systems in marine, RV and other 12V/24V applications.

Key Features:

• Replaces two individual high-amp relays with one compact module, saving installation space
• 3-position manual override knobs let you force each relay open or closed, or lock it in either position
• Front-facing LED status indicator, with a remote LED that mirrors the on-device LED
• Programmable through dip switches under the protective cover, with a configuration guide on the reverse
• Stainless steel terminal studs and self-locking flanged nuts resist corrosion
• Protective cover shields terminal studs and cable terminal edges from accidental shorts to each other or to ground
• Includes a weatherproof circuit label set (40 circuit labels) with blank labels for custom applications
• Sealed construction with a vent that regulates internal pressure to help keep moisture out

Specifications:

• Total continuous current: 500 A
• Max cranking current: 1500 A
• Voltage range: 8-36 VDC, auto-ranging for 12V and 24V systems
• Off-state current draw: 1.3 mA
• State change current: 5 A at 12 VDC, 3 A at 24 VDC
• Mechanical switching life: 1,000,000 cycles
• Terminal stud torque: 120 in-lbs

This unit is part of the Egis XD Series. Its low standby current draw and compact size make it a good choice for managing house and starting battery banks.
