AHI Series – Class 2 PCB Power Transformers

With UL Class 2, CE and 115/230VAC input capabilities the AHI series is often referred to as the “international transformer”. Inherently limited and with a 4200Vrms dielectric strength, between primary and secondary, this series is designed for the most demanding applications.

Key Benefits:
  • 115/230VAC input capability depending on wiring schematic.
  • Specially designed bobbin wall slots eliminates all wire crossovers.
  • Dual bobbin non-concentric design reduces capacitances and eliminates the need for an electrostatic shield.
  • Precision pin alignment for easy drop-in application.
  • Key Features:
  • 50/60Hz
  • UL recognized Class 2/3 (UL 1585-1 & -3) File No. E214561
  • Class B (130°C) Insulation system.
  • Built to meet requirements of IEC EN61558-1 & VDE safety standards.
  • Insulating shroud provides 4200 Vrms Hi-POT dielectric strength.
  • Bobbin and shroud material meet UL 94V-O flammability requirements.
