"Silver Angel" SL Series Flat Printed Circuit Board Welded Power Transformer
Features
① The fully-encapsulated printed circuit board can be directly welded and assembled, and has a perfect outline.
② It has a low mounting height, compact structure, and is solid, vibration-proof, moisture-proof, flame-resistant, and has high insulation withstand voltages.;
③ It is easy to use and reconfigure, and alternative input/output voltages can be obtained by changing the connections of the primary and/or secondary.
④ It has a built-in temperature protector, making it safer to use.
Ambient Conditions
① Temperature: -25℃~+70℃;
② Relative humidity: ≤90% at 40℃;
③ Atmospheric pressure: 860~1060mbar (650~800mmHg approximately).
Insulation Rating
Class F (155℃).
Safety Features
① Dielectric resistance: >1000MΩ in normal condition;
② Insulation withstand voltages: 3750 V (50HZ)/1 min;
③ Insulation impact strength: Continuously 20 times impact of 6KV(50HZ)/50μS;
④ Fire retardancy: In conformity with UL94-V0.
