BLOCK 2.3VA PCB Transformer, Dual 12V

The BLOCK 2.3VA PCB Transformer is an encapsulated safety isolating transformer engineered for the secure electrical separation of input and output circuits. Its design enables the creation of Safety Extra-Low Voltage (SELV) and Protective Extra-Low Voltage (PELV) systems by limiting the output voltage, ensuring operator safety in sensitive applications.

Constructed with permanent corrosion protection and a high insulation value, the transformer achieves maximum electrical reliability through its XtraDenseFill resin encapsulation. This robust encapsulation, along with self-extinguishing potting and hood materials, provides exceptional durability and fire safety.

A key advantage is its operational resilience; it is inherently short-circuit proof and built to perform reliably in high ambient temperatures. Despite its high output capability, it maintains a minimal footprint, making it ideal for space-constrained installations. The unit features dual primary and dual secondary windings, allowing for flexible series or parallel connections to suit various voltage requirements.
