EZPPS programmable power supplies include both a three- and two-digit LED display for voltage and current readouts. They feature a maintenance timer to alert users to the unit’s expected lifetime and are available in 30-, 60-, 90-, 120- and 240-W models. EZPPS keeps track of the total number of hours a unit has been on and provides an alarm for preventive maintenance and replacement before an unanticipated outage. Also included is a built-in display that provides, at a glance, additional information without the need to connect a meter.
