The output can be adjusted over a 45 to 58V or 22.5 to 29V range by means of a front-panel voltage adjustment potentiometer or by a remote DC input control signal from a controller.
Other features include a Class B EMI input filter, 87% efficiency, output overvoltage and current limiting protection, and front panel LED status indicators.
System monitoring and control functions include AC good, DC good, thermal alarm, remote enable, remote adjust and sensing.
