High Quality Three Phase Active&Reactive Current transducer
Transmitter’s internal circuit isolated by switching power supply (85-275V),input single,appendix power
supply and transmitter output.It has advantages of high accuracy, low power consumption, environmental
adaptability, fast response, plastic shell, new appearance, light weight,ect.
2).Using environment:temperature:0 to +45C,relative humidity:no more than 93%(no condensation)
3). Input:current:0 to 5A, voltage:0 to 450V,frequency:45 to 65HZ
4). Appendix Power Supply:AC/DC85-270V
5). Output mode: DC:DC4 to 20mA(Other parameters can be customized)
6). Power consumption:current input circuit:less than 0.5VA,voltage input:less than 0.5VA,power input circuit:less than 5VA
7). Response time:less than 150ms
8). Weight:360g(package weight:450g)
9). Frame size:110mm*75mm*120mm
10). Insulation strength:withstand voltage AC 2kv,50HZ in 1min
Transmitter can be installed on the Transmitter screen and meter screen,using the install mode of standard guide rail and screw fix.
Details are in the following:
1).It is must to check if there are damages outside,wiring terminal is right.Wiring diagrams refer to Diagram 1 and Diagram 2.
2). Before input rated value,the Transmitter should be heated no more than 30min.
3).The internal structure of 3phase 3wire is not the same as 3phase 4wire,so they can not be used interchangeably.When purchasing,please pay attention to the wiring diagram.
4). The Transmitter has three insulates of input signal,transform output,appendix power supply.
Diagram 1 3phase 4wire
Mode 1(3 Current Transmitters):3Phase 4wire work, has central.
Diagram 2 3phase 3wire
Mode 2(2 Current Transmitters):3Phase 3wire work
1). Before using,transmitter need to power for 15 minutes.
2).It must prevent vibration and shock, and can not to be used in places of excessive dust and harmful gases.
3). Input wire should not be too long.If the tested signal input is long,please use shielded twisted pair cable.
4). If it need to stored for a long time,avoid direct light with the temperature of -10 to 70 Celsius.Please power once more than 4hours in 3months.
5). The PT signal can not be used as the appendix power supply,except the PT has enough power.
6). The terminal screw must be tighten.Ensuring input/output wiring tough is reliable.
7). If the meter need to be checked,the accuracy of check machine should higher than class0.1.
