TOS8870A
Global Standard of the Withstanding Voltage/ Insulation/ Resistance Testers
Applying to various safety standards
Capable to perform the continuous Withstanding Insulation
Resistace Testing.
TOS8870A is a combination of a withstanding voltage tester and an insulation resistance tester,
and it is capable of performing Withstanding Voltage Test and Insulation Resistance Test in one
continuous process. (Choice of setting arrangement: AUTO ACW→IR, AUTO IR→ACW,
MANU.ACW, MANU.IR)
The Tester can provide a maximum output of 5kV and an output capacity of 500VA (AC), and
can be used for withstanding voltage test for the electrical equipment and components in
compliance with major electrical standards and ordinances. As for the insulation resistance
tester, the tester has two ranges of 500V/1000MΩ and 1000V/2000MΩ.
