Technical Details – Components for Fluorescent Lamps
Starters for fluorescent lamps
As mentioned above, the operation of fluorescent lamps also requires starters in addition to ballasts. A
distinction is made between glow starters, which are also available with automatic cut-outs, and electronic
starters. The correct choice of voltage and power range is crucial. Starters are available for 220–240 V
and for 110–127 V mains voltage. The latter are also required for twin-lamp operation (e.g. 2x18 W at
230 V).
Operating SL-series VS ballasts (100–127 V) depends on the use of a 220–240 V starter as these operating
devices are high-reactance transformers that supply higher voltages to the lamp. Starters should only
be used with starter contacts with a hardness value of at least HB 100.

Technical specifications
Operating voltage range
VS ballasts can be operated at the specified mains voltage within a tolerance range
of ±10%
Leak current
≤ 0.1 mA per ballast
Error current Impulse-resistant leak-current protection must be installed. Distribute the luminaires to
phases L1, L2 and L3; install tri-phase FI switches. If permissible, install FI switches with
30 mA leak current; connect no more than 15 luminaires as FI switches can be triggered
at half the leak current value.
Power factor Inductive ballasts: λ 0.5
Parallel-compensated ballasts: λ 0.85
