WATT DC-DC POWER SUPPLY ALLEN BRADLEY 1771 SYSTEM
FEATURES Active Current Sharing Full Redundant Operation Swap Capability Remote Sense Monitor Alarm Status Hold Time 20mS Multiple Input Voltage Ranges Input Output Protection
Input
Input Power: watts max. Status Alarm: Signals input voltage drops below specified range. Transient Protection: Fuse back back zener diodes protect against catastrophic failure. Reverse Polarity Protection: Unit will turn verse polarity detected. Isolation: 725V minute, 850V second. Conditions: input output input case.
General Description
lntronics' PLC4xxx external DC-DC power supply designed completely safely power fully loaded Allen Bradley 1771 PLC. PLC4xxx operated "stand alone" "redundant mode" high availability system configurations. units mount externally 1771 maximize available slots provide amps 5Vdc power most standard 1771 rack configurations. units contain appropriate monitoring alarm circuitry interface with 1771 rack. event input power failure, units have sufficient hold time ensure orderly system shutdown.
Output
Output Voltage: 4.87 5.25 (normal range 1771 system, including noise ripple.) Current Range (non-redundant): min., max. Current Range (redundant): min., max. Remote Sense: Maintains accurate voltage with
General Specifications
Size: 3.8" Refer figure Power supply System Interface: Refer fig. stand alone configuration. Refer fig. redundant mode configuration. Fuse: user accessible. Input Cable: wire.

recommended cable wire).
Overcurrent: Unit will shutdown 110-130% rated output current. Reset cycling power seconds. Overvoltage: Unit shuts down output voltage exceeds redundant configuration, range Undervoltage: Provides status alarm. Turn Time: sec. max. specified output range. Ripple: max. p-p, ripple noise: max. measured power input (through cable). Load Sharing: Active load sharing enabled redundant configuration. Hold Time: min. after ride-through under worst case line load conditions. Transient Load: Maintains specified operation load change. Shutdown result transients greater than 25%. Status Output: Closed relay contact when outputs within specified range. Output: Power good signal 1771 rack.
