摘要
采用IDT计量芯片90E24,实现了电流规格为1(100)A的单相高准确度、宽量程智能电能表的设计。产品测试结果表明,电能表在20mA^100A的电流范围内,计量准确度优于±0.2%,温度系数优于±150×10-6/℃。
A design of 1(100)A single phase energy meter is presented by using IDT's metering IC 90E24.The test results show that the meter achieves ±0.2% accuracy over current range of 20mA ~ 100A,and temperature coefficient less than ±150×10^-6/℃.
