BLOCK VB Series Safety Isolating Transformer, 1VA - 12V

The BLOCK VB Series Safety Isolating Transformer is engineered to provide secure electrical isolation between input and output circuits, making it a fundamental component for safety-critical applications. Designed to create SELV (Separated Extra-Low Voltage) and PELV (Protected Extra-Low Voltage) circuits, its output voltage is intrinsically limited, ensuring operator safety in accordance with stringent regulations. Its construction is optimised for reliability in demanding environments, featuring permanent corrosion protection and a high insulation value achieved through advanced XtraDenseFill resin encapsulation. This robust potting not only shields the internal windings from moisture and contaminants but also contributes to maximum electrical reliability over the product's lifetime.

A key advantage of this transformer is its dual output voltage configuration, offering flexibility for either series or parallel connection to suit various circuit requirements. It is inherently short-circuit proof, providing an additional layer of protection and durability. The self-extinguishing potting material enhances safety by preventing the spread of flame, making it suitable for installations where fire risk is a consideration. Despite its compact dimensions, it is designed to perform reliably at high ambient temperatures, delivering consistent power in a minimal footprint.

Ideal for a wide range of industrial and power management scenarios, this encapsulated transformer is a dependable choice for control circuits, instrumentation, lighting, and other applications where safe, isolated low-voltage power is essential. Its through-hole mounting design facilitates secure and stable installation on printed circuit boards (PCBs), ensuring a solid mechanical and electrical connection.
