- Contact protected screw connection terminals complying with UVV BGV A3
- Simple mounting thanks to robust metal fixing rail with oval slots
Prose
Autotransformers
Autotransformers are the efficient and ideal solution for minor voltage adjustments. Compact designs can be provided depending on the voltage difference. Autotransformers feature lower losses compared with isolating transformers with the same power rating. The transformers without galvanic isolation also feature inverse operation. BLOCK's standard range features power outputs of between 150 VA and 250,000 VA
- Efficient solution for minor voltage adjustments
- Inverse operation possible
- Power output: 250 VA to 250,000 VA
Applications
- Autotransformer for adjustment of the voltage on the input and output sides with no requirement for electrical isolation.
