Hansen electronic converter
Electronic converters have several advantages over conventional wire wound transformers; especially for small portable signs. Firstly they are considerably lighter and smaller than an equivalent output wire wound transformer. Because they have constant current characteristics they will light a tube to the same brightness be it short or long, and because the operating frequency is 20,000 Hz this light is flicker free.
When you combine this with inbuilt protection devices and elegant design you have the perfect power supply for most portable signs.
HANSEN Neon Converters - with choice of indoor and outdoor version, dimmable and non-dimmable, range from 20mA to 150mA.
