BLOCK PCB Mount Safety Isolation Transformer 230V 2.8VA - 15V
BLOCK PCB mount safety isolation transformer, 230V input, dual 15V 2.8VA output. Encapsulated, short-circuit proof for SELV/PELV circuits.
The BLOCK PCB Mount Safety Isolation Transformer is a compact, high-reliability mains transformer designed for voltage adjustment and secure electrical isolation. It functions as a safety isolating transformer, effectively and safely separating the input and output sides of a circuit. This makes it suitable for creating Safety Extra-Low Voltage (SELV) and Protective Extra-Low Voltage (PELV) circuits, where the limited output voltage enhances user safety.
Constructed with permanent corrosion protection and a high insulation value, this transformer delivers maximum electrical reliability. This is achieved through its XtraDenseFill resin encapsulation, which not only protects the internal components from environmental factors but also provides a self-extinguishing potting material for added safety. The transformer is designed to perform reliably in high ambient temperatures, making it suitable for a wide range of industrial and electronic applications.
