Vishay Dale
Low Power Transformers
Dual Primary - Dual secondary
115/230 Volts
FEATURES
• PC pin mounting
PL-22, PL-23, PL-24
• Provides isolation from power line
RoHS
• Dual Primary for operation at 115 V or 230 V,
50/60 Hz
COMPLIANT
• Dual Secondary for series connection obtains twice
winding voltage with center tap or for parallel connection
obtains twice winding current rating
