Multifunctional Current Converters of the HJ-A series
The Current Converters of the HJ-A series excel by their multifunctionality, their digital interface and the little space they require on a mounting rail. The sensors of the HJ-A series meter the root mean square value (true RMS) of the current of 1 to 3 phases, as desired, and optionally also the voltage, the effective power and reactive power, the energy in kWh as well as the frequency and the power factor (cos φ).
It iDue to their excellent durability (MTBF > 30.000 h), the sensors are particularly suited for use in automation. The sensors of the HJ-A series offer a simple and reliable way to monitor currents and voltages.
