Autotransformer

Autotransformer, PVAT3
Data Standards/Certifications Applications Downloads
General Data
  • Input rated voltage 3 x 690 Vac
  • Output rated voltage 3 x 400 Vac
  • Rated power 650 ‑ 1386 VA
  • Ambient temperature +60° C
  • Protection index IP 00
Advantages
  • Low weight and small size (compared to isolating transformers)
  • Very high efficiency
  • Very good corrosion protection and low noise thanks to BLOCKIMPEX vacuum impregnation
  • Quick to cable up thanks to the use of spring‑loaded terminals
