Victron Energy Current Transformer 100A:50mA for MultiPlus-II (1m) - CTR110000500

The Victron Energy CTR110000500 Current Transformer is an external AC current-sensing accessory designed for compatible MultiPlus-II and MultiGrid-II systems. It measures AC current through a conductor and provides the sensing input required for supported system functions such as PowerControl, PowerAssist, and optimized self-consumption. 

This CTR11-series version uses a jack connector and is intended for compatible older MultiPlus-II units that use this current-sense connection. Victron also offers CTR12-series versions with wire-end termination for newer MultiPlus-II units, making it important to verify the current-sense connection on the inverter/charger before ordering. 

Key Technology

• External AC Current Sensing
  The transformer clips around the applicable AC conductor and provides external current sensing for compatible Victron inverter/charger installations. 

• 100A Current Rating
  Designed for external current-sensing applications with a rated primary current of 100A.

• 50mA Transformer Ratio
  Uses a 100A:50mA current-transformer configuration for the designated Victron sensing application.

• PowerControl Support
  Enables compatible MultiPlus-II and MultiGrid-II systems to use external current measurements when implementing Victron PowerControl functionality.

• PowerAssist Support
  Provides the external sensing required for supported PowerAssist configurations, allowing the Victron system to respond to AC load conditions according to its configuration. 

• Self-Consumption Optimization
  Can be used in compatible systems to optimize self-consumption through external current sensing. 

• Jack Connector Version
  The CTR11-series transformer uses a jack connector, distinguishing it from CTR12-series versions that use wire-end termination.

Best Uses

• Compatible MultiPlus-II Systems
  Designed for supported MultiPlus-II installations that use the jack-style external current-sense connection.

• MultiGrid-II Systems
  Suitable for compatible MultiGrid-II applications requiring external AC current measurement.

• PowerControl Applications
  Useful where the inverter/charger needs external AC current information to implement configured PowerControl functionality.

• PowerAssist Applications
  Provides current sensing for supported installations using PowerAssist to coordinate available AC input power with inverter assistance.

• Self-Consumption Systems
  Suitable for compatible energy systems where external current sensing is used to optimize self-consumption.
