Specifications
Input Voltage: 105-125 VAC, 50-400 Hz, single phase.
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.
Normal mode:
Nominal voltage shown in table.Backup mode:
0.2 volt less than nominal voltage shown in table.
Load Regulation: ±0.05% (Dynamic regulation - does not include 0.2 volt shift which occurs during switching to lower-set backup supply.)
Line Regulation: ±0.05%
Ripple: 1 mV rms.
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.
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.
Voltage Monitor Circuits: One for each power supply. Relay contacts switch when output voltage decreases approximately 2 volts from the nominal rating (approximately 3 volts for outputs over 48 volts), and may be used to control an external failure alarm.
Alarm Relay Contact Ratings: 120 VAC, 8A / 60 Vdc, 1A. (To comply with SELV requirements, limit switched voltage to 60 Vdc / 42 VAC.)
Output Metering: A separate voltmeter for each output (standard). Ammeters available; see Options.
Temperature Coefficient: 0.02%/�C (Typical)
Ambient Operating Temperature: -20 to +71�C.
Storage Temperature: -55 to +85�C.
Terminal Strip Cover: Clips on.
