LW-7142 Power up Back side Packaged Packaged

 

 

 

Withstand voltage tester is the effective and direct way to test insulation strength for electric equipments. It check dangerous flaws and make sure electric equipment continuous working. It typically used to test insulation strength for all kinds of electrical equipments, components like capacitors, insulation materials.

 

Feature:

*Small size ,light weight

*Easy operation, botton lock

*Provide 10 groups memory setting, each group could choose four kinds working mode,3 steps

*128×64 dot matrix LCD display, test mode is clear at glance

*Rising voltage gradient according to time, real-time analysis, looking for breakdown point

*Safe electrical function

*Lower limit on current Settings, intelligent alarm

*Arc detection function(1-9grades)

*Provide remote PLC control interface and could choose RS232/GPIB communication port
