STANDARD OR CUSTOM MAINS TRANSFORMERS?

The list below shows standard designs of transformers which we have supplied in the past and these can be repeated. Generally however customers prefer to specify a custom design. The price depends on the size code letter For size information see Package Options. There is no extra charge for a custom design.

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

To order a custom design please submit your specification using the link: Custom Mains. We will send you a firm quotation and a design reference so you can order from our webshop.

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. For help to calculate HT voltages and currents for various filter and rectifier circuits see How to Specify HT Windings

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.
Non standard primary windings are also possible

We offer these transformers in three package styles, and optional hum band. If you request an internal electrostatic shield the size may have to be increased.

MAINS TRANSFORMERS Note: Voltages and currents are AC RMS values. *=Centre tapped CLICK HERE FOR DIMENSIONS
