Current Transformer 100A:50mA for MultiPlus-II (1m) Wire-end

In a marine electrical room, a technician installs this current transformer around the AC output cable of a Victron MultiPlus-II inverter/charger to feed precise current measurements to the system's energy monitoring. The 100A primary rating suits typical 230V shore power and generator inputs, while the 50mA secondary output connects directly to the MultiPlus-II's current sense terminals.

Key specifications

• Primary current rating: 100 A
• Secondary current rating: 50 mA
• Current ratio: 2000:1
• Cable length: 1 meter with wire-end termination
• Ring-type current transformer for easy pass-through installation
• Compatible with Victron MultiPlus-II inverter/chargers
• Frequency range: 50/60 Hz
• Internal diameter: 10 mm
• Enclosure material: ABS plastic, black

Why choose it

This transformer delivers accurate current measurement for energy management in Victron systems. Its split-core design allows installation without disconnecting cables, saving time during setup. The 1-meter wire-end leads provide flexibility for routing to the MultiPlus-II's sense inputs, and the robust ABS housing ensures durability in demanding environments.

Ideal use cases

• Monitoring AC input current from shore power or generator in marine and vehicle installations
• Measuring output current of MultiPlus-II to track energy consumption
• Integrating with Victron GX devices for remote monitoring and logging
• Retrofitting existing systems with current sensing for advanced control

Good to know

The transformer is designed specifically for the MultiPlus-II series, ensuring correct scaling and compatibility. Its 50mA secondary output matches the inverter's input requirements, eliminating the need for additional signal conditioning. With a 10mm internal diameter, it accommodates common cable sizes used in these systems.
