Block Through Hole PCB Transformer 230 V ac Primary Voltage 15 V ac Dual Secondary 22 VA PT 22/2/15

Block PT 22/2/15 is a through-hole PCB transformer with a primary voltage rating of 230 V ac and dual secondary outputs at 15 V ac each, delivering a total power of 22 VA. Its design incorporates vacuum epoxy resin moulding to UL94-V0 standards, providing excellent electrical insulation and mechanical robustness for demanding applications.

The transformer supports series or parallel connection of dual secondary windings, although for specific VDE approvals, certain output configurations should not be connected in series. The PT series transformers are protected by an internal positive temperature coefficient (PTC) device, enhancing safety by preventing damage from short circuits.

The compact construction (64 x 46 x 54 mm) with double section glass fibre reinforced polyamide bobbins results in low inter-winding capacitance and reduced radiated noise. Its efficiency rating of 83% ensures minimal losses and low temperature rise during operation, supporting continuous industrial and electronic use.

Designed to operate reliably up to a maximum temperature of 40°C and frequencies from 50 Hz to 60 Hz, this transformer meets EN 61558 safety standards and enjoys certifications including VDE, ENEC 10, and UL recognised component status.

Typical applications include power supply circuits in industrial, commercial, and electronic equipment, offering short-circuit proof functionality for the PT series in compliance with relevant standards.

This transformer features a through-hole mount type for secure PCB installation. Dual secondary windings with single primary allow for series or parallel connection. Vacuum epoxy resin moulding to UL94-V0 rating provides excellent insulation.

Internal PTC device offers short-circuit proof protection in the PT series. High efficiency of 83% reduces power loss and heat generation. Compact size optimizes PCB space usage. Low inter-winding capacitance and radiated noise suit sensitive electronic circuits.

Certified to EN 61558, VDE, ENEC 10 and UL standards. Manufactured in Germany for quality assurance. Suitable for industrial and electronic power supply applications.
