Electronic TL-lamp starter
Product specification
UBA2000T
FEATURES
• Electronic starter, fully compatible with conventional
glow-switch starters
• Reliable and instant ignition
• Accurate defined preheat time derived from the mains
frequency
• Increased starter life since no mechanical parts are
used
• No radio-interference (according to “IEC926 10.5”)
• Automatic reset after interruption of supply voltage
• Large operating temperature range: −40 to +85 °C
• Maximum current protection of the preheat current
• Ignition shut-off at end of lamp life; no overheating of
load.
GENERAL DESCRIPTION
The UBA2000T is an integrated circuit for electronic
TL-lamp starters and is fully compatible with conventional
glow switch starters. The circuit controls the preheating
and ignition of the lamp. The preheat time is well defined
without spread, since it is derived from the mains
frequency. When the lamp fails, ignition is shut-off after 7
ignition attempts. The circuit has an automatic reset when
the supply voltage is interrupted.
