Product speciﬁcation

Electronic TL-lamp starter

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.
