产品classification
The open loop current sensor based on Hall effect principle can measure DC, AC, pulse and various irregular waveform currents under the condition of electrical isolation between the primary side and the secondary side.
Based on the measuring principle of the Hall Effect, the current of DC, AC, pulsed or various irregular waveforms can be measured under the condition of a galvanic isolation between primary and secondary circuit.
