Electric valve solar power supply system
In reviewing energy requirements first, a typical remote valve actuator site will have some sort of communication, whether it's licensed radio, cellular, or satellite. This same site will likely have a small PLC or SCADA system. In the event of a power failure, several days of UPS backup power is desirable – enough time. The instantaneous power required by a valve actuator depends on the application. Electric motors from less than 1 horsepower to several 10's of horsepower are. The power requirements of a remote actuator system are an entirely different matter; especially where standard AC motors drive the actuator. AC motors, whether. Depending on the size of the valve and the stroke time required, there are alternatives to consider. Several manufacturers of actuators offer 24/48 Volt DC powered. The voltage of the actuator motor is also an issue. The industry habit is to specify 480 Volt 3-phase motors. In the case of Solarcraft's inverter, 120/240 single/split phase.
