standard EN 60335-1:2005
Primary voltages
from 12 V to 250 V or 2 x 12 V to 2 x 125 V
Secondary voltages
from 2 V to 38 V or 2 x 2 V to 2 x 19 V
Capacity up to 3.6 VA
• Further voltages on demand
• Short-circuit-proof
• Vacuum-encapsulated, bobbin with dual chamber
windings
• Temperature class ta 40 °C/F and ta 70 °C/F
• High electrical safety and long service-life properties
• Quality test certified per item
• Excellent temperature fluctuation resistance properties
• Self-extinguishing cast housing and sealing material
Several hundreds of types provide high electrical safety and
long service-life for printed circuit boards, household appli-
ances, leisure electronics, heating and control technology as
well as in assembly techniques. Transformers for special
requirements with lower open-circuit (no-load) loss capacity
are also available in the range.
Enhanced customer benefit due to ongoing high quality
standards throughout 40 years experience in transformer
technology.
