DCP

DC VOLTAGE AND CURRENT, TEMPERATURE MEASUREMENT DEVICE

DCP is a multifunction device for measuring electrical quantities on DC lines.
The voltage measurement is done directly by the power line of the DCP.

The current measurement is performed by Hall effect transducer that provides an analog signal precise, repeatable and fast. Transducer allows an immediate installation, without supply interruption, because it is has to be fixed with a plastic clamp, at cable conductor or at the copper bar. Once fixed on the conductor, the Hall transducer must be calibrated with the measured current value.

DCP can be optionally equipped for the acquisition of up to 2 temperature measurements from environmental probes PT1000. The temperature measurements are carried out every second.

DCP communicates with Modbus RS485 network; all the communication parameters (address, baud rate, stop bits, parity bits) can be programmed.
