Modular Redundant Systems
using Switching Regulated Power Supplies
AC-DC single output
- Shipped Within 9 Days
- Five Year Warranty
Input Voltage: 90-265 VAC, 49-420 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.
Inrush current: Cold start, (thermistor limiter) 20A peak @115 VAC; 40A peak @ 230 VAC.
Startup Time: 800 mS typical.
Power Factor: 0.99 (typical) at 115 VAC, 60 Hz and full load. Complies with EN61000-3-2.
Remote Sensing: Compensates up to 0.5 volt drop per output line (1 volt for 55 to 125 volt models), within the limits of the output voltage adjustment range.
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 switchover to lower-set backup supply.)
Line Regulation: ±0.05%
Load Protection: Overvoltage protection.
Overload/Short Circuit Protection: Current limiting with automatic recovery.
Overvoltage Protection: Automatic recovery.
Polarity: Output is floating; either positive or negative output terminal may be grounded or floated up to 300 volts above ground.
Drift: ±0.1% maximum over 8 hours, after 30 minute warmup.
Output Monitoring: Output Present green LEDs are located on each power supply (DC on) and on the Integration Module.
Alarm Relay Contact Ratings: 120 VAC, 8A / 60 Vdc, 1A. (To comply with SELV requirements, limit switched voltage to 60 Vdc / 42 VAC.)
Interconnection: The Integration Module has two 24 inch long cables.
Holdup Time: 16 mS minimum.
Transient Response: 300 µS to return to ±1% of output setting. Maximum of ±3% output excursion following a load step change from 50% to 100%.
Switching Frequency: 100 kHz (Typical).
Isolation: Input to output, input to case; 300 Vdc.
Output to case; 300 Vdc.
Temperature Coefficient: 0.02%/°C (Typical).
Thermal Protection: Thermostat, self-resetting.
Cooling: Forced air cooled; air enters rear of power supply and exits from top.
Ambient Operating Temperature: 0 to +71°C.
Storage Temperature: 40 to +85°C.
Mounting: Threaded mounting holes permit mounting to a chassis,
cabinet wall or bracket, or they may be used on a test bench or tabletop.
To mount from the power supply side of the mounting surface or for DIN rail
mounting, see Accessory Mounting Kits.
