Closed Loop Hall Effect Current Sensor, AC/DC 0-2000A

SUCH Hall effect current sensor, AC/DC 0-2000A, enables accurate measurement of alternating, direct, and pulsed currents through zero-flux technology with closed-loop compensation and demodulation. It provides galvanic isolation between primary and secondary circuits, with a UL94-V0 flame-retardant housing suitable for industrial environments. The through-hole non-contact structure accommodates conductor sizes from 20.5×10.5mm to 52×32mm. Operating with a ±15VDC power supply, the current sensor offers 0-4VDC or 0-±5VDC output signals, applicable in UPS systems, battery storage, switch-mode power supplies, and inverter circuits.
