FEATURES
•PC pin mounting
•Provides isolation from power line
•Dual Primary for operation at 115 V or 230 V,
50/60 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: Split-section winding for increased
dielectric strength between primary and secondary
windings plus reduced interwinding capacitance
