In detail:
• Safe shutdown of the power supply to defective lamps or
at the end-of-life due to End-of-Life detection according to Test 2
Shutdown in the event of broken filaments, no inserted lamp or air
leakage
• Compliance with European safety standards (EN 61347-2-3)
• Protection against short duration voltage surges (DIN VDE 0160)
and transient overvoltages
• Low housing temperatures allow the mechanical design of lighting
fittings with F- and FF- as well as M- and MM-approval mark
(EN 60598/DIN VDE 0710 and DIN VDE 0711)
• Can be used in emergency lighting systems according to
DIN VDE 0108

for T5/ ∅ 16 mm-fluorescent
lamps (FH ® …HE, FQ ® …HO and FC ® ) can be operated on sinusoidal AC
voltage and DC voltage The recommended voltage intervals depend on the
design of the specific circuits.
The following chapters show the recommended voltage ranges and the
behaviour of the ECG at overvoltage and undervoltage.
2.4.1 Overvoltage and its
Reason
It is called an overvoltage if the ingoing voltage is significantly higher
than the nominal value.
In general, we have to differentiate between two overvoltages which
also can have different reasons.
1. Transient overvoltage with a typical duration of milliseconds.
This overvoltage can be caused by:
- Switching of inductive loads such as welding machines, elevators
alternators etc.
- lightening
Quasi-stationary overvoltage with a duration from a few minutes to hours.
This overvoltage can be caused by:
-
different loads on the mains side (interruption of the neutral
conductor in 3-phase installations plus an additional asymmetric
