BLOCK VB Series Safety Isolating Transformer - 12V
Compact BLOCK 500mVA safety isolating transformer for SELV/PELV circuits. Encapsulated, short-circuit proof, for industrial & safety applications.
The BLOCK VB Series Safety Isolating Transformer is a compact, high-reliability component engineered for critical safety applications. It functions as a safety isolating transformer, providing safe electrical isolation between the input and output sides. This design is essential for creating Separated Extra-Low Voltage (SELV) and Protected Extra-Low Voltage (PELV) circuits, where the limited output voltage is a key safety feature.
Constructed using advanced XtraDenseFill resin encapsulation, this transformer offers permanent corrosion protection, a high insulation value, and maximum electrical reliability. The robust potting material is self-extinguishing, adding a further layer of safety. The unit is inherently short-circuit proof, ensuring dependable operation and protection for connected equipment.
Designed to perform in demanding conditions, it is suitable for high ambient temperatures and achieves a minimal physical size despite its capable output. A versatile feature is its dual secondary output voltage, which allows for flexible series or parallel connections to suit various circuit requirements.
This encapsulated PCB-mount transformer is a cornerstone for applications where safety, reliability, and space efficiency are paramount. Its through-hole mounting design ensures a secure and stable installation on printed circuit boards, making it an integral part of sophisticated electronic assemblies.
