12 Design no.
Current values and power consumption varies with temperature conditions. Values shown in table are based on 30°C.
In the AC/DC conversion type, AC power is used to activate the DC solenoid by the built-in rectifier, and it comes with the characteristics featured by DC solenoids. This means that the items given for the DC solenoids apply for the maximum flow.
