Toroidal Transformers Built In Europe

QUALITY, GOOD DELIVERIES, VERY COMPETITIVE PRICING

All transformers are built and tested in accordance with the following standards:

IEC 742, EN60742, VDE 551, PN-88/E 08105

Guaranteed features:

  • Double insulation on primary leads
  • Insulation class B (130 deg C)
  • Insulation break down voltage min 5000V AC (less than .750 mA at 3750 V)
  • Built in primary winding thermal cut off at 115 deg C (upon request)
  • Power ranges: From 10 VA to 2500 VA
  • Input voltages as required (See transformer information/design sheet)
  • Up to 10 secondary voltages
  • Frequencies 50 to 400 Hz (Higher for audio transformers)
  • Private labels if required

We can also build all other devices on toroidal cores. Inquires are welcomed.
