Short circuit proof PCB transformer, safety isolating transformer

VB 2,8/2/9

Characteristics

General data

The PCB transformers of the VB series provide galvanic isolation of the primary circuit from the secondary circuit and are designed with a special construction to ensure absolute short-circuit safety. Additionally, they meet all requirements for supplying SELV (Safety Extra Low Voltage) circuits.

Benefits

 Safety isolating transformer according to EN (IEC) 61558-2-6

 Minimal size with high performance

 With dual output coils for series or parallel connection

 Absolutely short-circuit proof

 Self-extinguishing encapsulation material
