  • Specifications
SFY-211O power box is one of the auxinliary unit of control room instructments of DDZ-S series,,is regulator unit to supply power for units of  DDZ-S series instruments,high performance
Of voltage regulator.This power box can covert AC 220V to DC 24V ,over current、 over voltage、short-cicuit protection、warn(contact signal) and other funcions.If have a backup power,when the fault condition occurs,automatic access to backup power,then DDZ-S series instruments can work normally, form a non-outage system,so greatly strengthened the reliability of DDZ-S series system .
