HJ0602 electrical impulse voltage tester, with an output voltage of up to 12kV (±5%), accurately generates 1.2/50μs standard impulse waveform (wavefront time 1.2μs±30%, half-wave time 50μs±20%), complies with IEC 60335-1 Clause 14 standard, has built-in overvoltage and overcurrent protection, and can automatically or manually detect transient overvoltage, electrical clearance and creepage distance of household appliance components. It is widely used in household electrical safety performance testing.
