Block PCB Transformer 2 x 9 V AC 2 Output Pin, 3.2 VA, 230 V AC Primary, Short Circuit Proof VB 3.2/2/9

Block VB 3.2/2/9 PCB Transformer is a robust power supply component engineered for PCB mounting in electronic and industrial applications. With a primary voltage rating of 230 V AC at 50 to 60 Hz and dual secondary outputs of 2 x 9 V AC, it provides reliable power conversion with a power capacity of 3.2 VA. This transformer features a pin mount style with compact dimensions of 41 mm length, 30.8 mm width, and 35 mm depth, allowing integration into tightly packed circuit boards.

Designed for high reliability, the VB series transformers are inherently short circuit proof and encapsulated with vacuum epoxy resin moulded to UL94-V0 flame retardant rating. The double section glass fibre reinforced polyamide bobbins ensure durability and mechanical strength. The transformer operates with an efficiency rating of 58%, resulting in low temperature rise and minimal energy loss, suitable for demanding industrial conditions.

This model complies with several stringent international standards and safety approvals including cURus, ENEC 10 (VDE), UL 5085-1/-2, CSA 22.2 No.66, and IEC 61558-2-6, confirming its suitability and safety for professional use. The maximum operating temperature is rated at 50°C, supporting stable performance under thermal stress.

Its low inter-winding capacitance and low radiated noise make it an excellent choice for sensitive electronic devices and industrial control systems. The extra fixing holes available on higher power models enhance secure mounting on printed circuit boards.

The Block VB 3.2/2/9 transformer is manufactured in Germany, ensuring premium quality and rigorous testing, including 100% electrical and flash tests. It is ideal for applications in industrial machines, laboratory equipment, HVAC controls, manufacturing automation, water treatment systems, and general electronics power supplies requiring reliable 2 output voltage sources on PCB form factor.

Dual secondary 9 V AC outputs facilitating series or parallel configurations suitable for various circuits. Short circuit proof design enhances equipment safety and longevity. Compact pin mount transformer ideal for PCB integration in constrained environments.

Extensive compliance with international approvals like UL, VDE, ENEC, and CSA ensures safety and quality. Vacuum epoxy resin moulded casing provides flame retardant protection to UL94-V0 standards. Manufactured with double section glass fibre reinforced polyamide bobbins for superior mechanical durability.
