Block VB2.8/2/12 2.8VA Safety Isolating Transformer 230V to 2x12V

The Block VB2.8/2/12 2.8VA Safety Isolating Transformer converts a 230VAC mains input to a dual 2 x 12VAC output with a rated power of 2.8VA. It is a compact, encapsulated safety isolating transformer designed to create SELV (Safety Extra-Low Voltage) and PELV (Protective Extra-Low Voltage) circuits by limiting the output voltage, supporting user safety in a range of low-voltage applications.

Overview

The transformer is encapsulated in XtraDenseFill resin, which protects the internal components from environmental factors. The potting material is self-extinguishing, providing enhanced safety. The transformer is inherently short-circuit proof and designed to operate efficiently in high ambient temperatures. Its dual 12VAC output allows series or parallel connection configurations, offering flexibility in circuit design. With a compact footprint, it provides a high output from a minimal size and mounts to printed circuit boards (PCBs) via through-hole pins.
