Design feature: Outputs VCC\/2 (e.g., 2.5V @5V) when no\r\ncurrent flows. Voltage shifts ±2V (±50A) proportionally. Q2: Can it measure AC\r\ncurrent? Yes! Bandwidth supports 50\/60Hz AC (max 120kHz). Use VIOUT–VCC\/2 for\r\nbidirectional measurement. Q3: How to reduce electrical noise? Add RC filter\r\n(e.g., 1kΩ + 100nF) on VIOUT. Ensure power supply ripple \u0026lt;50mV. Q4: Why avoid\r\n\u0026gt;5.5V supply? Exceeding 5.5V risks IC damage. For 12V\/24V systems, use LDO\r\nregulator (e.g., AMS1117-5.0). Q5: Isolation failed after 50A surge? Copper\r\npath tolerates 2× overload (100A). Check IP+\/IP– traces for thermal damage;\r\nmax ambient temp ≤150°C.\u003c\/p\u003e \r\n\r\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\r\n  \u003cul class=\"a\"\u003e\r\n         \u003cli\u003eHigh Accuracy Current Detection 10-bit resolution; 0.1% linearity; 40mV\/A sensitivity; factory calibrated for precision; Suitable for industrial and consumer applications\u003c\/li\u003e\r\n         \u003cli\u003eWide Operating Range \u0026amp; Stability -40C to +150C; 2.4kV isolation voltage; 120kHz bandwidth; stable performance under high overcurrent conditions\u003c\/li\u003e\r\n         \u003cli\u003eLow Power Consumption \u0026amp; Efficient Design 13.5mA static current; 100 copper path resistance; 72-hour operation with 2000mAh battery; low power loss\u003c\/li\u003e\r\n         \u003cli\u003eEasy Integration \u0026amp; Compatibility PCB mountable; compatible with STM32, Arduino, Raspberry Pi; ratiometric output (VCC\/2 at 0A); simple setup required\u003c\/li\u003e\r\n         \u003cli\u003eRobust Build \u0026amp; Reliable Performance Lead-free construction; 2 overload tolerance (100A); thermal protection; no calibration drift; suitable for long-term use\u003c\/li\u003e\r\n  \u003c\/ul\u003e","brand":"MusRock","offers":[{"title":"Default Title","offer_id":44154579484852,"sku":"B0FMNV3ZKZ","price":113.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9906\/1172\/files\/B0FMNV3ZKZ.jpg?v=1775787840","url":"https:\/\/auspowers.com\/products\/cjmcu-758-acs758lcb-050b-pff-t-50a-bidirectional-hall-current-sensor-120khz-2-4kv-isolation-aec-q100","provider":"AusPower Australia","version":"1.0","type":"link"}
