1.Features:
- Fully-encapsulated printed circuit board being able to be directly welded
and assembled.
Perfect outline;
- Low mounting height, compact in structure, solid, vibration-proof, moisture-proof,
flame-resistant and high insulation withstand voltages;
- Easy to use and reconfigure: alternative input/output voltages can be obtained
by changing connections of primary and/or secondary;
- Built-in temperature protector, safer in application
2.Ambient Conditions:
- Ambient temperature: -25...+70°C;
- Relative humid <90% 40°C;
- Atmospheric pressure: 860~1060mbar (650~800mmHg approximately);
3.Insulation Rating: Class F (155°C).
4.Safety features:
- Dielectric resistance: >1000M in normal condition;
- Insulation withstand voltages: 3750V (50HZ)/1 min;
- Insulation impact strength: Continuously 20 times impact of 6KV (50HZ)/50mS;
- Fire retardancy: In conformity with UL94-Vo.
