double display instrument voltage 10-250VDC,AC 10-280V and current AC 0-1000A. Major use in welding machine  

welding machine instrument, voltage meter, ampmeter

Double display voltagemeter and ampmeter

Major use in welding machine and measure voltrage, current

Can be display voltage and current of welding machine at the same time !!!

The size of PCB is 78x78mm

the distance between installation hole is 67.3mm

the size of installation hole is 3mm

1. the first line can be display voltage and that measuren range is DC10-250V or AC 10-280V
2. The second line can be display current and that measure rnage AC1000A (via shunt)

You are only fixed it in display window of welding machine via the installation hole.

and then set color sheet under windows of welding machina. fixed easy and reduce the cost. 

At the same time, can be display voltage  and current !!!! 

All of the chip parts was set to PCB through Chip mounter of YAMAHA. very fast ,perfect, accuracy!

70-80% of components is from the international famous manufacturer!

 The time of aging is 5-6 hour so that each meter have consistent quality!

 At the same time,all of products must be checked twice so that gurantee quality of each meter!
