DETAILED DESCRIPTION

DCT1

DCT1 is a direct connection energy transducer for DC systems up to 1000 V dc and current up to 600 A dc, equipped with Modbus RTU or SML communication port. Dedicated versions of the DCT1, provided with evaluation certificate, implementing 256- bit or 384- bit signature on Modbus RTU or 384- bit signature on SML, are suitable for installation on electric vehicle chargers that requires Eichrecht certification.

Applications

DCT1 can be installed in any DC switchboard with a rated current up to 600 A to monitor energy consumption or production and the main electrical variables. The main application is within a DC fast charger for electric vehicles, thanks to the 70 °C maximum ambient temperature and allowed maximum current and voltage.

With the evaluation certificate according to IEC 62052-11, IEC 62052-31,VDE-AR-E 2418-3-100 Annex A, WELMEC 7.2 and the signed data transmission able to guarantee data source authenticity, application for Eichrecht certification, required for EV charger by the German law, is easily possible.

Cable loss compensation is able to calculate the losses due to the cable resistance from DCT1 to the connection point to measure only the energy actually provided to the car.

Benefits

• Easy and robust mounting.DIN rail mounting permits easy positioning before fixing DCT1 on the back panel using standard screws.

• Tamper proof. The protection cover can be sealed to avoid access to both current/voltage connections and to communication terminals.

• Secure and signed data transmission. Transmitted data can't be corrupted thanks to the embedded signature algorithm that ensures data source authenticity. The public key can be read easily via Modbus RTU or by the QR code printed on the front.

• Quick configuration. Easy configuration via Modbus RTU using the UCS configuration software, available for download free of charge.

• Accurate measuring.DCT1 complies with the precision International standard IEC 62053-41 guaranteeing the highest accuracy from 1% to 100 % of the measuring range.

• Temperature calibrated. Able to work in an extremely wide temperature range thanks to the temperature drift compensation exploiting a calibration method based on two temperature sensors.

• Clear and effective diagnostics. Correct operation is immediately visible through the warning and status LEDs, and real- time diagnostics via Modbus. They control over range and overtemperature.
