Low Power Transformers
Dual Primary - Dual secondary
115/230 Volts
FEATURES
PL-22, PL-23, PL-24
• PC pin mounting
• Provides isolation from power line
• Dual Primary for operation at 115 V or 230 V, ^RoHS
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
• 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

ELECTRICAL SPECIFICATIONS
Input Voltage: 115 V 60 Hz or 230 V 50 - 60 Hz
Output Power Rating:
PL-22, PL-42 = 1.5 VA
PL-23, PL-43 = 4.5 VA

• PL-22, PL-23, PL-24: Concentric windings for increased
coupling, decreased leakage reactance and improved
regulation
• PL-42, PL-43, PL-44: Split-section winding for increased
dielectric strength between primary and secondary
windings plus reduced interwinding capacitance
