DIN rail Active Energy meter, single-phase, direct 40A with RS485 output

The new Energy Meter C18WSL040MD3AI 1 din module meter with RS485 Modbus output.

Thanks to the front touch screen button it’s possible to set the parameters such as modbus addresses and display additional measurements: A, V, Ptot and Energy.

The FRER ETHERNET gateway allows you to connect up to 32 C18WS to an Ethernet network (using a single IP address). The integrated FRER mini WEB-SERVER, which can be consulted via any browser for Internet navigation, allows the display and recording, with automatic or manual start, of the measurements, which can then be downloaded in .csv format

Sensor ø110mm for Type B Earth Leakage Relays

TDB110

TDB series sensors are able to measure AC and DC currents with a DC-10kHz bandwidth, and 1mA resolution. TDB sensors have an integrated degauss function with DC offset zeroing, which is by relay command. This function sets to zero the Dc current measuring errors (DC offset) caused by terrestral magnetic field, permanent magnets, DC coil, temperature drifts, mechanical shocks or vibrations. The measuring error of the RMS current (AC+DC) is proportional to the line current and it depends on the geometrical layout of the conductors passing through the sensor hole. It also depend on the distance and the geometrical layout of the nearby conductors passing outside the sensor hole. The IΔn setting <100mA will be possible only by centering the conductors and with controlled environment conditions (temperature, vibration, EMI).
