Low Power Through-Hole Transformer
Dual Primary - Dual Secondary
115 V/230 V
FEATURES
• PC pin mounting
• Provides isolation from power line
PL-22, PL-23, PL-24
• Dual Primary for operation at 115 V or 230 V,
50 Hz/60 Hz
• Dual Secondary for series connection obtains
twice winding voltage with center tap or for parallel
connection obtains twice winding current rating
• Modification to these standard items are available as
speciality products
• Laminated
construction
for
low-cost
industrial
applications, including power supplies, controls and
instrumentation
• Mounting bracktes and bobbin standoff are available
• PL-22, PL-23, PL-24: Concentric windings for increased
coupling, decreased leakage reactance and improved
regulation
PL-42, PL-43, PL-44
• PL-42, PL-43, PL-44: Split-section winding for increased
dielectric strength between primary and secondary
windings plus reduced interwinding capacitance
ELECTRICAL SPECIFICATIONS
• Compliant to RoHS Directive 2002/95/EC
Input Voltage: 115 V 60 Hz or 230 V 50 Hz to 60 Hz
