The Victron Energy CTR120002050 Current Transformer is an external AC current-sensing accessory designed for compatible Victron MultiPlus-II and MultiGrid-II systems. It uses a 100A:50mA transformation ratio and a wire-end termination for connection to compatible current-transformer inputs. Victron lists this exact SKU as the wire-end version for MultiPlus-II applications. 

When used with supported Victron equipment, the current transformer provides external current sensing for functions such as PowerControl, PowerAssist, and self-consumption optimization. The extended lead allows the sensing point to be positioned away from the inverter/charger when required by the system layout. 

Key Technology

• 100A:50mA Current Transformation
  Converts current flowing through the monitored AC conductor into a proportional low-current measurement signal for compatible Victron equipment.

• External Current Sensing
  Allows a compatible MultiPlus-II or MultiGrid-II system to measure AC current at an external sensing point rather than relying only on measurements inside the inverter/charger.

• PowerControl Support
  External current measurement can be used by supported Victron configurations to help manage the load placed on a limited grid or generator AC source.

• PowerAssist Support
  Provides current-sensing information required by supported PowerAssist configurations, allowing compatible inverter/chargers to coordinate battery-supplied power with the available AC source.

• Self-Consumption Optimization
  Supports compatible Victron energy-storage configurations that use external AC current sensing to measure power flow and manage self-consumption.

• Wire-End Termination
  The CTR12 series uses a wire-end connection rather than the jack connector found on corresponding CTR11 current-transformer models.

• Remote Measurement Point
  Designed for installations where the AC conductor being monitored is located at a distance from the compatible inverter/charger.

Best Uses

• Victron MultiPlus-II Systems
  Designed for compatible MultiPlus-II installations requiring external AC current measurement.

• Victron MultiGrid-II Systems
  Can be used with compatible MultiGrid-II configurations that support this external current-transformer interface.

• PowerControl Applications
  Useful where a compatible Victron system needs external current information to manage demand against an available AC source limit.

• PowerAssist Applications
  Supports properly configured systems that combine available grid or generator power with inverter power from the battery.

• Self-Consumption Systems
  Suitable for supported Victron energy-storage configurations that require an external measurement point for AC power-flow management.

• Remote AC Sensing Locations
  Useful where the required measurement point is physically separated from the MultiPlus-II or MultiGrid-II installation.
