BLOCK 2.8VA Safety Isolating Transformer, 230V to 2x12V

The BLOCK VB2.8/2/12 is a compact, encapsulated safety isolating transformer designed for reliable voltage adjustment and secure electrical isolation. This robust transformer is engineered to create SELV (Safety Extra-Low Voltage) and PELV (Protective Extra-Low Voltage) circuits by limiting the output voltage, ensuring user safety in a wide range of low-voltage applications.

Featuring permanent corrosion protection and a high insulation value, it delivers maximum electrical reliability. This is achieved through its XtraDenseFill resin encapsulation, which not only protects the internal components from environmental factors but also provides a self-extinguishing potting material for enhanced safety. The transformer is inherently short-circuit proof and designed to operate efficiently in high ambient temperatures, making it suitable for demanding environments.

Its dual 12VAC output allows for versatile series or parallel connection configurations, offering flexibility in circuit design. With a compact footprint, it provides a high output from a minimal size, ideal for space-constrained applications such as printed circuit boards (PCBs), where it mounts via through-hole pins.
