BLOCK Encapsulated Safety Transformer 3.2VA 2x 18V

The BLOCK Encapsulated Safety Transformer 3.2VA 2x 18V is a robust PCB-mount isolating transformer designed for safe electrical isolation between the input and output sides. It enables the creation of SELV and PELV circuits thanks to its limited output voltage, making it a reliable choice for safety-critical applications in industrial and power management settings.

Engineered for high ambient temperatures and inherently short-circuit proof, this transformer delivers consistent performance while maintaining a minimum size at high output. The dual primary (2 x 115V) and dual secondary (2 x 18V) windings allow for flexible series or parallel connections, adapting to a variety of circuit configurations.

Featuring XtraDenseFill resin encapsulation, the unit provides permanent corrosion protection, high insulation value, and maximum electrical reliability. The self-extinguishing potting and hood material further enhances safety in demanding environments. This transformer is through-hole mounted, offers a power rating of 3.2VA with a current rating of 88mA, and operates across a frequency range of 50Hz/60Hz.
