Noise performance, achieved through proprietary amplifier and filter design techniques Integrated shielding greatly reduces the death of capacitance coupled current conductors from high dV/dt signals, and prevents misalignment from drifting on the high side for high voltage applications Improvement of Total Output Gain and Offset Error Trimmed Temperature Small size, easy to install capability High reliability single-chip Hall IC Low power consumption: 100 internal conductor resistance Isolation allows the use of economy and high edge Currently sensing in high voltage systems 3 to 5.5 V single power supply Typical bandwidth of 120 kHz Response step input current 3 output rise time Output voltage is proportional to AC or DC current Cutting factory Stable output bias voltage Near zero hysteresis The PCB circuit color may be different in different batches, which will not affect the use Specifications: A: ACS758LCB-050B module Colour: Random Color, don't accept the specified color Material:pcb Package Contents: 5 x Hall current sensor modules Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
