Output voltage: 0~250V/50Hz (AC)
Output current: ≤10A
Output power: ≤3KVA
Power supply time
1~99s (The equipment automatically judges that it is
disconnected at the voltage peak for testing)
Test voltage: 10~199.9V( resolution: 0.1V, accuracy:
±(reading*1%+1V))
Test time: Test after disconnecting for 1 second
Number of tests: 1~99 times
Test impedance: 1000MΩ
Alarm range: Settable (normally 34V or 60V)
Judgement: Sound and light alarm, and cut off the voltage at
the same time
Working power: 220V/50Hz
The residual voltage tester is designed according IEC60601-1:1988 clause 15 and IEC60335-1:2016 clause 22.5. The equipment has a high enough test impedance, it uses the method of simulating the disconnection of the plug to disconnect the appliance from the supply mains at the instant of voltage peak. It is used for the residual voltage test of electrical appliance like medical equipment and household appliances.
Working principle
The appliance is supplied at rated voltage, any switch is then placed in the off position and the appliance is disconnected from the supply mains at the instant of voltage peak, 1s after disconnection, the voltage between the pins of the plug is measured with an instrument that does not appreciably affect the value to be measured, the voltage shall not exceed 34V as per IEC60335-1/60V as per IEC60601-1.
