Block PCB Transformer 18 V AC 2 Output Pin, 115/230 V AC Primary, 5000 V Isolation, 53x22.6x44 mm, 980 g, FL 6/18

The Block FL 6/18 PCB Transformer is a robust and compact transformer engineered for electronic and industrial power supply solutions on printed circuit boards. This model delivers a stable 18 V AC dual secondary output, suitable for a variety of control, measurement, and general automation applications requiring reliable voltage step-down or isolation functionality. Its primary winding accommodates both 115 V AC and 230 V AC inputs, making it efficient for use in regions with differing grid standards.

Designed using high-quality glass fibre reinforced polyamide bobbins, the FL 6/18 offers a low-profile form factor - measuring 53 mm in length, 22.6 mm in width, and 44 mm in depth - ideal for compact PCB installations. The vacuum epoxy resin molding (UL94-V0 rated) provides exceptional insulation, thermal stability, and mechanical protection, ensuring the internal components remain safeguarded in high-performance settings.

This transformer features dual secondary windings, allowing series or parallel connection options, suitable for flexible voltage or current delivery as needed by the circuit design. The 5000 V isolation voltage between windings maximizes user safety and protects downstream circuits from electrical faults and noise. Its low inter-winding capacitance and minimized radiated noise contribute to reliable performance in sensitive electronic environments.

Rated for continuous operation up to 40°C, the FL 6/18 complies with major international standards: C-UL-US, VDE 0570 Teil 2-1, VDE 0570 Teil 2-4, DIN EN 61558-2-6, IEC 61558-2-4, IEC 61558-2-1, and more. This assures compatibility and acceptance in project designs and panel builds across the globe.

Installation is simplified by the 2 output pin mounting style with additional fixing holes for secure board attachment. This transformer is 100% electrically and flash tested for assured quality control, and it weighs 980 grams, reflecting the substantial build suited to both industrial and high-integrity commercial power applications.

Use cases for the Block FL 6/18 PCB Transformer include power supply isolation in laboratory instruments, measurement equipment, control panels, automation modules, and reliable voltage conversion across various electronic, manufacturing, or industrial sectors where robust, compact transformers are required.
