One-Shot Phase Control
U490B
Description
The monolithic integrated bipolar circuit, U490B, is a
one-shot power control circuit, designed to control the
thyristor which is mainly used in electric stapler devices.
The IC is preferred to realise a one-shot phase control,
where any phase angle and thus any intensity of the load
voltage is adjustable.
After successful triggering and the following delay time,
an ignition pulse at the output is released. A further trig-
gering is only possible after the elapse of the delay time.
Features
D Phase controlled thyristor ignition
D Triggering with time delay
