Ballasts from ELT have been tested and qualified by Spanish and European certification organizations.
All the ELT ballasts are manufactured according to the national and international standards corresponding to each product.
The mains and lamp connections depend on the ballast type and as a general are:
with choke type starter, 0,5 to 1mm plug-in or 2,5mm screw-in.
with autotransformer type starter and rapid start SR or AR 215mm screw-in
Range of ballasts for use with linear and compact fluorescent lamps in indoor installations. Their main families are:
Flat Series section 28 x 41
Slim series section 28 x 28
Low Loss Ballasts, Ballasts for 125
Range of ballasts which covers all the types which produce a rapid ignition in linear fluorescent lamps. They can be used in indoor installations without starter or external capacitor. Their main families are:
Rapid Ignition Ballasts
Electronic Ignition Ballasts
High and Very High Emission Ballasts, ...
Range of ballasts for use in outside signs. Without the need for a starter or external capacitor. Their main families are:
IP67 ballasts with electronic starter
IP67 Ballasts with standard starter, ...
Range of ballasts for indoor use to supply high frequency lamps, reducing the power consumed. They can be used in installations without a starter or external capacitor. Their main families are:
Instantaneous Ignition Ballasts
Pre-heating Ignition Ballasts
The efficiency of a ballast-lamp assembly is given by the ratio: lamp flux emission-total power absorption, and is obviously, related to the lamp characteristics as well as to the ballasts own losses.
Until today, no international standard has established limits for the actual losses of the ballasts, but their use, practice and technological evolution, as well as characteristics, have gradually defined a classification, which, more specifically for ballasts used with fluorescent lamps, is the following:
Very Low Loss Ballasts
Traditional Ballast (normal losses)
High Loss Ballasts
In order give to the user
