—— SGS

Good day and thank you for you According to the sample of the instrument you provided, we are very satisfied with our test. We want to change the order from 2 to 10. The following is the order details of our Asia Pacific branch. Would you please send me the quotation of the corresponding office? So we can generate an order to confirm it. Thank you.

Limited short-circuit test , IEC 62368-1-Annex R


R.3 Test method
The source shall be applied to the EUT via the mains cord supplied or specified by the equipment manufacturer. Where there is no mains cord supplied or specified, a 1 m length of 2,5 mm 2 or 12 AWG shall be used. For DC sources, the cable shall be sized for the maximum rated current of the equipment.
To conduct this test a short-circuit in the equipment to the earth connection of the equipment shall be introduced. The point at which this is done is depending on the equipment. After consideration of the equipment construction and circuit diagrams, the short-circuit shall be introduced between the phase conductor, at the point nearest to the input (the point of lowest impedance), and the protective bonding path under consideration. There may be more than one point at which this short-circuit may be applied to determine the worst case.
The protective bonding conductor is connected to a source capable of supplying an AC or DC current, as appropriate to the EUT, of 1 500 A under short-circuit conditions, and using a source voltage equal to the rated voltage or any voltage within the rated voltage range of the equipment. In cases where the prospective short-circuit current seen by the equipment is known, then the source used for test shall be able to supply that current under short-circuit conditions. The manufacturer shall state the prospective short-circuit current that has been used in the evaluation in the safety instructions. The overcurrent protective device protecting the circuit under consideration (in accordance with Clause R.2) is kept in series with the protective bonding conductor. The power supply cord, if provided or specified, shall remain connected when conducting the test.
The limited short-circuit test for protective bonding conductors in a potted or conformally coated assembly is conducted on a potted or coated sample.
The test is conducted two more times (for a total of three times, on a different sample unless the manufacturer agrees to conduct the test on the same sample). The test is continued until the overcurrent protective device operates.

First charge the battery inside the device, discharge it to the set voltage, and then realize the instantaneous high current test. The discharge time and voltage can be set. After the discharge is completed, it will automatically charge for the next test. The discharge current is recorded during the test, and the system will automatically generate a current-time curve.



▪ automatic/manual features;

▪ discharge voltage and limit protection time can be set;

▪ waveform curve analysis function;

▪ with overpressure overcurrent protection function;

▪ operation interface (as shown below)
