"Smurf" TL 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 is compact in structure, solid, vibration-proof, moisture-proof, flame-resistant, and has high dielectric strength.
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 is economical and affordable, with a competitive price.
Ambient Conditions
① Ambient temperature: -10℃～+40℃;
② Relative humidity: ≤90% at 40℃;
③ Atmospheric pressure: 860～1060mbar(650～800mmHg approximately).
Insulation Rating
Class B (130℃).
Safety Features
① Dielectric resistance: >1000MΩ in normal condition;
② Insulation withstand voltages: Better than GB/T15290 standard requirements.
③ Fire retardancy: In conformity with UL94-Vo;
④ Basis insulation impulse level: Continuously 10 times impact of 6KV (50HZ)/50μS;
