Product Description

Block PT 22/2/12 PCB Transformer is a reliable through-hole mounted transformer featuring a 230 V AC primary input and dual secondary outputs providing 12 V AC. It delivers 22 VA power with a high efficiency of 77%, suitable for various industrial and electronic PCB applications where safety and performance are critical.

This transformer uses a single primary and dual secondary winding configuration allowing series or parallel connections as per system requirements. Its vacuum epoxy resin moulded construction achieves UL94-V0 flame retardant rating, enhancing operational safety and durability.

The device complies with VDE and UL certifications and meets EN 61558 and ENEC 10 standards, making it suitable for demanding environments and ensuring regulatory conformity. Its maximum operating temperature is 40°C with an operating frequency range between 50 and 60 Hz.

The compact dimensions of 64mm in length, 46mm in width, and 54mm in depth permit easy PCB integration with through-hole mounting. Additional design features include double-section glass fibre reinforced polyamide bobbins, low inter-winding capacitance, and low radiated noise, supporting stable and efficient electrical performance.

Weighing 565 grams, this transformer strikes a balance between robustness and manageable size. It is inherently short circuit proof due to its internal PTC device protection, making it ideal for industrial machines, laboratory electronics, power supplies, and manufacturing equipment requiring reliable isolation and voltage transformation.
