Switch Mode Power Supplies

Apart from a few specific applications met only by ‘linear’ types, Switch Modes are now the dominant power supply technology in production. This has been driven by the trend towards miniaturisation, portability and operational efficiency. The benefits of Switch Modes have meant the virtual elimination of the bulky step-down transformer/series regulator type linears. These have been replaced with ‘pulse width modulated’, high frequency power supplies capable of converting mains supply voltages world-wide down to useable, well-regulated DC power for a wide range of applications.

Our primary suppliers include ENG, FRANMAR, and ACCESS COMMUNICATIONS. We can generally source off-the-shelf configurations to meet most requirements and are happy to quote custom-builds for larger quantities.

The Government is proposing to regulate external power supplies (often known as ‘a.c. adaptors’, ‘plug packs’ or ‘power packs’) manufactured or imported for sale in New Zealand. It is currently proposed they will be regulated from 1 October 2008.
