U490B

One-Shot Phase Control

Description

The monolithic integrated bipolar circuit, U490B, is a After successful triggering and the following delay time,

one-shot power control circuit, designed to control the an ignition pulse at the output is released. A further trig-

thyristor which is mainly used in electric stapler devices. gering is only possible after the elapse of the delay time.

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.
