  • Very Small size and low weight compared with traditional stacked lamination types.

  • Extremely low level of radiated magnetic field

  • Very low induced noise (hum)

  • Very low iron loss.

  • 100% electrical and flash tested

  • High quality manufacturing and testing in accordance to EN61558, EN60742, EN60950, EN60065, VDE0551, VDE0550 and BS415

  • UL Recognised to UL506, under family approval file E215495

  • Primary-Secondary test voltage 4.0 KV (VDE 0550).

  • Primaries and secondaries for parallel or series connection.

  • Ambient operating temperature +60'C maximum.

  • Insulation Class A (105'C)

Specifications subject to change, Custom models available on request.

For 240 volt operation, connect primaries in series by connecting pins 5 & 4 together and apply 240 volts across pins 6 & 3.

For 120 volt operation, connect primaries in parallel by connecting pins 6 & 4 together and pins 5 & 3 together, apply 120 volts across pins 6 & 5.

To parallel the secondaries, connect pins 14 to 12 and 13 to 11 take the output across pins 14 and 13.

To place the secondaries in series, connect pins 13 to 12 and take the output across pins 14 and 11.

Dimensions in mm.
Electrical measurements @20'C ambient temperature.
