Ardat’s throttle 1019040003

Purpose of

is designed to ensure the ignition mode and limit the current of high -pressure discharge lamps when they are included in an alternating current network with a frequency of 50Hz with a rated voltage of 220V.

Scope

are used for installation in lamps.

The principle of action

The inclusion of a throttle in the AC circuit causes a phase shift between the voltage and current. When designating the throttle, the corner is usually indicated (COS F), on the value of which the current lags behind the voltage. It is also called power coefficient. Active power is determined by the work of voltage, current and cosine fi.
