Allen Bradley 1606-XL120E-3 Plc Power Supply 24-28V DC Allen Bradley 1606 Xl

Product Specification

               Redundant Power Supply Module AB 1606-XL120E-3 24-28V DC, 120 W, 3-Phase, 480V AC wide range
 
 
 
Input
Input voltage                     3 AC 400...500V, ± 15 % 47...63 Hz, suitable for IT power systems
Rated tolerances              (at 24V/5A)
• Continuous operat.         340...576V AC resp. 450...820V DC
• Short term (1 min.)          300...620V AC resp. 420...890V DC
 
Even if one phase fails, the unit’s operation with nominal current can be continued (limitations: EN 61000-3-2 (harmonic current emissions) is then not fulfilled, the unit has noise suppression level A instead of level B and the hold-up time is shorter). Continued operat. with two phases is also permissible; however, it reduces the unit’s reliability and lifetime.
Input current         3 x 0.5 A
Inrush current       typ. <25A at 575V AC and cold-start
 
If you intend to protect the primary side of the power supply with fuses or circuit breakers, 10 A (x3) slow acting fuses (HBC) or a supplementary protectors 1492- SP3C100 are recommended. In order to meet local requirements, please consult local codes and regulations for proper installation.
 
Harmonic current emissions (PFC)  acc. to EN 61000-3-2
Hold-up time                                     >16 ms (3 phase op. at 400V AC, 24V/5 A)
                                                         >10 ms (2 phase op. at 400V AC, 24V/5 A)
 
 
Efficiency, Reliability etc.
 
Efficiency                           typ. 89% (400V AC, 24V/5 A)
Losses                               typ. 15 W (400V AC, 24V/5 A)
MTBF                                 410.000 h acc. to Siemensnorm 29500
                                           (24V/5 A, 400V AC, TU = 40 °C)
Life cycle (electrolytics)     The unit exclusively uses longlife electrolytics, specified for +105°C.   
 
 
 
 
Start / Overload Behavior.
 
Startup delay                              typ. 0.1 s
Rise time                                     ca. 5...20 ms, depending on load
Overload Behavior                      – no disconnection, no hiccup if overloaded
• Special Overload Design          – high overload current (up to typ. 2⋅ INom), Vout is reduced with   
                                                      increasing current.
   (see diagram) 
• 20% power boost                      – 6 A short-term, at 45°C or forced cooling even continuous
 
Advantages:
• High short-circuit current, giving large ‘start-up window’: unit starts reliably even with awkward loads (DC-DC converters, motors).
• Secondary fuses operate more reliably
