FEATURES
•PC pin mounting.
•Provides isolation from power line.
•Dual Primary for operation at 115V or 230V, 50/60Hz.
•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 specialty products.
•Laminated construction for low-cost industrial applications, including power
supplies, controls and instrumentation.
•Mounting brackets 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.
