UI 30
Flat-type transformersOutput Capacity: 3.0 VA
• Capacity up to 16.0 VA
• Temperature class ta 70 °C/B, but not short-circuit-proof
• Test certifications to ENEC 05-, KEMA KEUR-,
CSA- and UL-regulations
• Vacuum encapsulated, bobbin type with dual chamber
windings
• Excellent temperature fluctuation resistance properties
• High electrical safety and long service-life features
• High voltage resistance
• Self-extinguishing cast housing and sealing material
• Item quality certification
Secondary protection by means of external PTC resistances.
Parallel to the cataloged UI 30 series transformers, HAHN
also produces other variants, e.g. with integrated thermo
fuse or thermo switch.
