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.
