CTClamp – Single Phase Current Transformer
The sensor is installed in the main electrical panel after the electricity meter and is connected via cable to the EVPoint EV7 and EV22 charging stations. It allows the station to monitor the power consumption of all devices in the circuit, and if the limit is exceeded, it will reduce the charging power.
By installing a sensor (current transformer) in the main electrical panel, the EVPoint EV7 charging station receives real-time data on the current consumption of all electrical appliances connected to the same electrical system. In the station’s settings, you can set the current limit of the main circuit breaker, and if the total consumption of the charging station and other appliances exceeds this limit, the station will reduce the charging power just enough to stay within the set threshold.
This ensures that the electrical network cannot be overloaded due to EV charging. In most cases, there will be no need to request an increase in your power allocation, because with the power regulation feature, you can rest assured that the main breaker will never trip. This allows you to charge your electric vehicle while using other high-power appliances at the same time.
The sensor is intended for installation in the main distribution electrical panel that powers the charging station. The current transformer is clamped onto the phase conductor. It is not necessary to disconnect the wire, as the transformer opens like a clip and locks in place once mounted on the cable. To connect the CT Clamp sensor to the charging station, a four-core cable must be laid between the panel and the charging point. An FTP cable can also be used, with four of its wires dedicated to the CT Clamp, and the remaining four for the “Dynamic Load Management” (DLM) function or for Ethernet internet connection.
