Short circuit proof PCB transformer, safety isolating transformer
VB 2,0/2/8 - Discontinued items – not for new applications
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
