1.8 KW Planar Power Transformer is the latest in a new series of planar magnetic components from Planar Magnetics Limited

Planar Magentics Ltd., designers and manufacturers of planar technology transformers and inductors have introduced the 64 series - the first in a wide ranging new family of Planar power transformers and inductors. The 64 series, with power ratings from 1kW to 3.5 kW offers a highly efficient thermal resistance between winding and mounting base. This results in higher power density and cooler operation. Winding Voltages are up to 700V; winding current up to 150A and switching frequency 50kHz to 250 kHz. The series is suitable for a wide range of applications including off-line. All materials are UL approved for class F operation. Options include electrostatic screening and customer terminations. The significant benefits of planar magnetic technology are several; - low leakage inductance and lower winding resistance are realized and a high consistency between components is assured. The mechanical benefits also contribute to the development of more efficient power converter products, The low profile of planar magnetic components opens up new design opportunities In many power circuits applications. They are better suited to heatsink mounted and high current connections are easier to make. Planar Magnetics Ltd operate a R&D facility and manufacturing plant specialising in the design of power components utilising planar technology. Experience includes high speed data transformers requiring high CMRR and low distortion through to 10 kW power transformers with high current outputs.
