MAINS TRANSFORMERS

Our mains transformers use M6 cores to ensure minimum loss and good regulation. Regulation is typically 5% or better and is compensated so that the specified voltage is correct at the stated load current. We offer two standard primary options:

  • European type: 240, 220, 200, 0, -10 volts taps.
  • World-wide type: Two separate windings with 120, 110, 0 volts taps. To be used in series or parallel.

We offer these transformer in three package styles, and optional hum band.  If you request an internal electrostatic shield the size may have to be increased. Prices depend on the size code letter.  For size information see Package Options. For help to calculate HT voltages and currents for various filter and rectifier circuits see How to Specify HT Windings

CUSTOM MAINS TRANSFORMERS are available at the same prices.

To order standard mains transformers please note the TYPE NUMBER and contact sales. We will make It possible to order using our online as soon as we can.
