Цифровой вольтметр и амперметр переменного тока 220В 380В 50А 100А с двойным дисплеем DL85-2041 2042

DL85-2041-2042 数字式交流电压表电流表是在同一仪表上分别显示被测量的交流电压和交流电流。仪表不需要另外增加工作电源和交流互感器（仪表自身配有精密互感器），测量非常方便及准确。广泛用于配电自动化，如稳压器，教学用具，家电维修，插板，家用小型配电箱，舞台音响，时序器等。（本款仪表可以直接代替老式85L17指针式交流电压电流表使用，无需改动原先面板开孔尺寸）

主要技术指标
1.测量精度1%±2个字
2.测量范围：交流电压AC 80-300V 200-450V，交流电流AC 0-50A 0-100A 1-200A
3.电源功耗：0.2VA
4.测量速度：约每秒2次
5.外形尺寸：70（长）*40（宽/高）*39（深）mm
6.开孔按装尺寸：68*38mm（嵌入式按装）
7.（外置100A互感器孔直径15.5mm）可以满足国标21-25平方（mm)标准铜线穿过
8.（外置200A互感器孔直径24mm)可以满足国标30-45平方（mm)标准铜线穿过
9.型号说明：
1:DL85-2041型:互感器固定在仪表上面
2:DL85-2042型:互感器与仪表分离，互感器可以根据测量的实际位置安装，互感器二次端引线可以加长0.5-3米，不影响测量精度。

本仪表只适于纯交流50-60HZ的市电电源，不能用于方波逆变器输出以及修正弦波的正弦波电路上测量，否则仪表会被永久损毁！

下单须知如下
测量110V 220V电压请勾选AC80-300V,测量380V电压勾选200-450V的！测量电流在0.1-100A以内勾选固定式CT 0-50A或者勾选分体式CT 0-99.9A【测量精度不变】测量100A以上勾选199A【1.0A-199A测量精度不变】

DL85-2041 2042AC Digital Voltage & Current Meter

User Guides

DL85-2041 2042 AC digital meter can measure the voltage and current at same time. When it run, you need not to supply any work power and current transformer

Technical Indicators

1. Accuracy: 1%, 2 words

2. Displayer: AC voltage and current with 4-digial 0.39-inches LED;active  power, reactive

3.Measure Range:

      AC voltage: AC 80.0-300.0 V / 200.0-450.0V (Select specific type when order);

      AC current: AC 0.00-50.0A / 0.00-99.9A /1.0-199A the resolution ratio will change by itself , when

      input  current lower than 10.0A,the resolution ratio is 0.01A; when input current

       higher than 10.0A the resolution ratio is 0.1A;

4. Measuring Speed: 2 times per second;

5. Size: 70*40*39mm

6. Installation size: 68*38mm

Application Method

1.current transformer is installed on the meter surface.

2.Take care the sequence of connection:

1.Connect the current loop;

2.Supply the work power (220V)

3.When supply work power, do not touch any component in the bottom of meter.
