Victron Lynx Shunt VE.CAN: Battery Monitor Setup

Key Takeaways

• The Lynx Shunt VE.Can serves as the central battery monitor and primary system fuse holder in modular Lynx DC distribution systems.
• Supports heavy commercial DC currents: Current rating 1000 Adc continuous through solid Busbar dimensions (hxw) 8 x 30mm tinned copper busbars.
• Handles multiple nominal voltages: Supported system voltages 12, 24 or 48 V with a wide Supply voltage range 9 - 70 Vdc.
• Minimal quiescent current drain: Power consumption 60 mA @ 12 V 33 mA @ 24 V 20 mA @ 48 V.
• Standardized modular busbar interconnects: Busbar M10 connecting bolts.
• Accommodates main system protection: Fuse or fuse dummy M8 (a Mega fuse can be installed on the M6 bolts).
• High-speed digital networking: VE.Can RJ45 and RJ45 terminator ports communicating directly with GX devices.
• Includes dry-contact fault automation: Potential free alarm contact 3 A, 30 Vdc, 250 Vac.
• Built for rugged battery compartments: Unit weight 1.4 kg and Enclosure dimensions (hxwxd) 190 x 180 x 80mm.
• Resilient environmental ratings: Protection class IP22 operating from Operating temperature range -40 °C to +60 °C.

Modular Busbar Architecture & Current Measurement

The Lynx Shunt VE.Can is designed to sit directly between battery banks (connected via Lynx Power In) and DC loads/chargers (connected via Lynx Distributor). Its internal resistive shunt measures every ampere flowing into and out of the battery bank with laboratory precision.

The Victron Lynx Shunt VE.Can serves as a 1000 Adc modular battery monitor and main DC fuse holder across a 9 - 70 Vdc operating range for 12V, 24V, and 48V battery banks. It provides:

• DC Power & Shunt: 1000A Continuous, 8x30mm Copper Bars, M10 Interconnects, Low Power Draw.
• Fusing & Alarms: M8 Center Studs, M6 Mega Option, 3A Alarm Relay, Temp Sensor Port.
• Comms & Power: Dual VE.Can, RJ45 TermPlug, RJ10 PowerOut, NMEA2000 Data.

Installation Rules & Mechanical Assembly

1. Modular Bolting: Interconnect the Lynx Shunt VE.Can to adjacent Lynx modules using the supplied Busbar M10 bolts, torquing to 33 Nm on the Busbar dimensions (hxw) 8 x 30mm tinned copper conductors.
2. Main Fuse Placement: Install an appropriately rated CNN or ANL fuse on the center Fuse or fuse dummy M8 (a Mega fuse can be installed on the M6 bolts) studs, torquing to 14 Nm.
3. Wide System Voltage: Compatible with Supported system voltages 12, 24 or 48 V across a Supply voltage range 9 - 70 Vdc.

VE.Can Network Integration & Hardware Automation

The Lynx Shunt VE.Can provides full system telemetry to Cerbo GX and VRM portals:

• High-Speed VE.Can Bus: Connecting dual VE.Can RJ45 and RJ45 terminator sockets at 250 kbps allows GX system controllers to calculate accurate State of Charge (SoC), time-to-go, and consumed ampere-hours.
• Low Quiescent Draw: Maintains active telemetry with negligible standby loss: Power consumption 60 mA @ 12 V 33 mA @ 24 V 20 mA @ 48 V.
• Potential-Free Alarm Relay: The internal Potential free alarm contact 3 A, 30 Vdc, 250 Vac trips automatically on low SoC, high/low voltage, or blown main fuse events.
• Lynx Distributor Power: An onboard RJ10 socket provides power and blown-fuse detection logic to downstream Lynx Distributor modules.
• Rugged Housing: Encased in an ABS enclosure with Protection class IP22, Enclosure dimensions (hxwxd) 190 x 180 x 80mm, Unit weight 1.4 kg, and an Operating temperature range -40 °C to +60 °C.
