FEATURES
PL-22, PL-23, PL-24
Vishay Dale
•
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
•
PL-42, PL-43, PL-44:
Split-section winding for increased dielectric strength
between primary and secondary windings plus reduced interwinding
capacitance.
