CHCS-ITH-100SSeries high-precision current sensor
Product Introduction
CHCS-ITHThe series of precision, wideband, bipolar current sensors based on the principle of magnetic flux gate (non Hall) are mainly aimed at the fields of DC, AC, and pulse current measurement that require ultra-high accuracy. The primary and secondary currents are isolated from each other, and the safety performance is superior.

Application Connection and Instructions:
1. Test instructions:
By measuring the flow throughRMTest currentIsOrRMVoltage at both endsUR, can obtain the primary currentIP:
IP=KN*Is=KN* (UR/RM)
2. Instructions for indicator lights and signals:
Under normal working conditions, the effective indicator light is constantly on. If the indicator light goes out, it indicates that the current sensor is in a non-zero magnetic flux state, such as the bus current exceeding the range. At this point, the sensor enters a scanning state internally, and the output current is no longer proportional to the input current signal. Once the bus current falls back within the range, the sensor resumes normal operation.
be careful:
uISexistIPWhen flowing in the direction of the arrow, it is positive.
uThe temperature of the primary conductor cannot exceed100℃.
