Description
The ballast produces the required ignition voltage and lamp operating voltage. Ambient temperature variations are compensated by the preheating time of the fluorescent lamp electrodes. Operation at increased frequency gives a luminous efficacy 10–15 % higher than at 50 Hz, and ignition and burning take place without flicker. A variable preheating time extends lamp life, so lamps are replaced less often and maintenance costs are lower. High efficiency reduces the ballast's own heating and increases component life. All components are designed for the higher requirements of transport use.
How to choose
The size is selected for the specific vehicle, that is by on-board network voltage and lamp power. The available materials contain no detailed data by size, so parameters are agreed on request. For carriages, ships and buses also check the lamp type and installation conditions, and the design of the ballast simplifies service and repair.

FAQ
Which vehicles are EVG ballasts intended for?
For lighting passenger and freight vehicles, namely rail rolling stock, ships and buses.
What supply do EVG ballasts work from?
From on-board DC networks. They power fluorescent and other types of lamps.
How much higher is the luminous efficacy at increased frequency?
10–15 % higher than at 50 Hz. The lamp also ignites and burns without flicker.
Which fault conditions are the ballasts protected against?
Short circuit, no load, faulty lamp electrodes and reversed polarity at the input. Every ballast undergoes 100 % outgoing inspection.
How many such ballasts are already in service in transport?
The manufacturer has made them for over 40 years, and more than 500 000 ballasts are in use on various vehicles.
