Short circuit proof PCB transformer, safety isolating transformer
VB 1,5/1/24
Characteristics
General data
Notice of Product Adjustment
As part of the restructuring of our PCB transformer production processes, adjustments will be made to both the visual appearance and technical characteristics. Detailed information is available in the Product Change Notification under Downloads. Please note that slight variations in no-load voltages and efficiency may occur. The pinning remains identical to the previous version.
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
› Absolutely short-circuit proof
› Self-extinguishing encapsulation material
