UI 39 Flat-type transformators, output capacity up to 30,0 VA
 
UI 39 Flat-type transformators
  • Capacity up to 30.0 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.

 
Several hundreds of serial item sizes provide the highest degree of flexibility wherever flat-type construction components are required. Dual, primary and secondary voltages provide additional flexibility in development work. Approved under Standard EN 61558.

HAHN flat-type transformers UI 21, Ul 30, Ul 39, UI 48

An extensive standard range with capacities from 1.0 - 60.0 VA. HAHN transformers are quality products meeting all demands placed an highly developed electro-technical equipment. Of course, item quality certified, vacuum-encapsulated and tested with 6000V prim./sec. (VDE 0570 and CEE 15 regulations require only 3750 V). Leckage distance and air paths at least 10 mm. Temperature class ta 70'C/B as per VDE 0570, EN 61558 and CEE 15 regulations/standards. An innovative insulation technique in the provides for even greater primary and secondary voltage stability casting, in all sizes of the UI 30 to UI 39 types.
