BLOCK Transformer 3.2VA - 18V
BLOCK 3.2VA encapsulated safety isolating transformer. Features XtraDenseFill resin, dual secondary windings & through-hole PCB mounting.
The BLOCK Transformer 3.2VA is a high-performance safety isolating transformer designed for the safe electrical isolation of the input and output sides. Ideal for creating SELV (Safety Extra Low Voltage) and PELV (Protective Extra Low Voltage) circuits, this transformer ensures operational safety through its strict limit on output voltage.
Engineered for demanding environments, it is specifically designed to withstand high ambient temperatures while maintaining a minimum footprint at high output. A standout feature is the XtraDenseFill resin encapsulation, which provides permanent corrosion protection, a high insulation value, and maximum electrical reliability. Additionally, the unit is inherently short-circuit proof and utilises a self-extinguishing potting material for enhanced safety.
Featuring a single primary winding and dual secondary windings, this versatile transformer allows for series or parallel connection to suit various application requirements. It is designed for convenient through-hole mounting on printed circuit boards, making installation straightforward and secure.
Applications
This encapsulated safety isolating transformer is perfectly suited for industrial, power management, and safety applications where reliability and compact dimensions are critical.
