IEC 62368-1 Annex R Computer Controlled Restricted Short Circuit Test Machine

IEC 62368-1 Annex R Computer Controlled Restricted Short-Circuit Test Machine

Product Information:

This restricted short-circuit test machine is required by IEC62368-1:2018 clause 5.6.4.1&5.6.5.1, Annex R.

The restricted short circuit test device is used to test the protective grounding conductor and current protection circuit breaker 1500A. The purpose of this test machine is to verify that the protective connecting conductor used in the circuit protected by the device with a rated value not exceeding 25A is compatible with the fault current allowed by the overcurrent protection device, and to test the integrity of additional safety protection through such tests.

Test samples: audio, video, information and communication technology equipment.

Test principle:

The restricted short circuit test machine uses the energy storage device to realize the instantaneous high current test. The discharge time and initial voltage can be set. After the discharge is completed, it will automatically charge for the next round of test. During the test, the discharge current will be recorded to generate the current time curve.

Equipment features:

1. Large industrial computer.

2. Optional automatic current rise test, manual current rise test and impact quick break test, flexible and simple operation.

3. Real time display of output current and time results is intuitive;

4 Perfect over-current protection, arbitrary setting of target output current value, current upper limit and current withstand time.

5. With grounding detection function and zero return detection function, the test can be carried out after the grounding and zero return are determined, which is safe and reliable.

6. Approximation type current raising algorithm, when the set target output current is reached, the current tolerance timing will be automatic, and the motor will return to zero automatically after the timing is completed.

7. If the upper limit of the set output current is exceeded, the motor will automatically return to zero and give an audible and visual alarm.

8. Sophisticated anti-interference design of software and hardware, multiple anti-interference means, adapt to harsh electromagnetic environment.

9. It can be equipped with door interlock alarm, opening voltage verification interface, etc.
