SPECIFICATIONS (for Redundant Power Packages & Modular Redundant Systems)
Input Voltage: (A separate set of AC input terminals is provided for each power supply, so that if two sources of AC input
power are available, one may be used for each supply and so reduce the possibility of output dropout due to loss of input
power.)
Remote Voltage Sensing: Provision for sensing the output voltage across the load, so that drops in the load line are
compensated, is a standard feature.
Output Voltage:
Output Regulation:
Load Protection: Overvoltage protection.
Overload/Short Circuit Protection: Foldback current limiting with automatic recovery.
Polarity: Output is floating; either positive or negative output terminal may be grounded or floated up to 300 volts above
ground.
Output Monitoring:
Temperature Coefficient: 0.02%/°C (Typical).
Ambient Operating Temperature:
Storage Temperature:
(Rack Mounting & Wall Mounting)

Linear: 105-125 VAC, 50-400 Hz, single phase.
Switching: 90-132 VAC, 49-61 Hz, single phase.
Linear: –20 to +71°C.
Switching: 0 to +71°C.
Linear: – 55 to +85°C.
Switching: – 40 to +85°C.
Normal mode: Nominal voltage shown in table.
Backup mode: 0.2 volt less than nominal voltage shown in table.
Line: ±0.05%
Load: ±0.05% (Dynamic regulation - does not include 0.2 volt shift which occurs during switchover to lower-set
Redundant Power Packages: A separate voltmeter for each output (standard). Ammeters available; see Options.
Modular Redundant Systems:
backup supply.)
For models R24W7, RWL24W7, R28W7, RWL28W7, R48W7 and RWL48W7, the use of 30A lines is
recommended.
When operating on 50 Hz input, derate output by 5%.
