5.3.2 ACS-2 plus 12V version
Parameter
operating voltage range
current consumption
The door strike must be taken into consideration if its supply comes from the ACS-2 plus. The current
consumption of a door strike depends on the type, but lies somewhere between 200mA and 500mA.
The current consumption of an energized door strike must be known for each ACS-2 plus
when designing a 12V system.
The following drawing (powered on) shows the voltage drop of a 1.5mm
power consumption of 1A is calculated for each ACS-2 plus.
Observe the outgoing and return line.
