ACS715 전류 센서 0A ~ 30A
(ACS715 Current Sensor Carrier 0 to 30A)
개요
- 본 제품은 Allegro사의 30A ACS715 전류센서를 탑재한 제품입니다.
- 30A 사이의 전류를 입력 받아 측정된 전류 값을 아날로그 전압(133mV/A)으로 출력합니다.
- 5V 시스템과 동작합니다.
특징
-
Current sense: 0.133 V/A1 Minimum logic voltage: 4.5 V Maximum logic voltage: 5.5 V Supply current: 13 mA - Designed for unidirectional input current from 0 to 30 A, but the sensor will provide meaningful feedback for currents as low as -1.5 A, and the robust IC can survive up to five times the overcurrent condition.
- Conductive path internal resistance is typically 1.2 mΩ, and the PCB is made with 2-oz copper, so very little power is lost in the board.
- Use of a Hall effect sensor means the IC is able to electrically isolate the current path from the sensor's electronics (up to 2.1 kV RMS), which allows the sensor to be inserted anywhere along the current path and to be used in applications that require electrical isolation.
- 80 kHz bandwith that can optionally be decreased by adding a capacitor across the board pins marked "filter".
- High accuracy and reliability: typical total output error of ±1.5% at room temperature with factory calibration, an extremely stable output offset voltage, and almost zero magnetic hysteresis.
- Automotive-grade operating temperature range of -40°C to 150°C.
