Characteristic curve and setpoint values
The pressure converter is activated by a pulse-width-modulated signal. The duty cycle is between 15 and 65 % (depending on engine operation). The supply vacuum is 700 mbar. Depending on the duty cycle, the vacuum can be continuously adjusted.
Characteristic curve valid for 950 mbar
