4.Warning
Under no circumstances should both ends of the fixing bolt simultaneously contact the metal chassis or framework as this would create a potentially dangerous 'shorted-turn'.
5.Certificate
We have abtained CE CQC RoHs ULISO9001:2015,SGS and IEC approval. We guarantee quality is the first.
Test process:
1). No-load test (included no-load voltage,no load current and no load loss)
2). IInductive voltage test
3). Load test (load voltage and temperature rise
4). Temperature rise test .
