Rongtech Industry(ShangHai) Inc., RTC100LA2 Series Closed Loop Mode Hall Effect Current Sensor Mechanical dimension(for reference only) Remarks：1. All dimensions are in mm. 2. General tolerance ±1mm. Directions for use 1.When measure current flows according to the direction of the arrowhead, Output terminal gets the same phase current. 2.The primary conductor should be≤120℃. 3.The dynamic performance (di/dt and the response time) is the best when the primary hole is fully filled with the bus bar. 4.The primary turns should be at the top of the sensor for the best magnetic coupling. 5.When the...
