How many thermoelectric valve drives can be connected to each VAA/S output?
This depends on the maximum Inrush current of the valve drive and the operating current of the valve drive.
The maximum inrush current of the VAA/S is 300 mA for 2 min at Ts up to 60 °C per output.
Ts is the surrounding temperature.
The maximum operating current of the VAA/S is 160 mA at TS up to 45 °C per output.
