Is used in many applications.
Use the B input code 20-60 V  or the 24 input code 20-32 V.


 

Input range Family codes
B = 20 - 60 Vd.c. PM50 PSC150 PM150  PU300 PU600
B = 20 - 72 Vd.c. PSE100
24 = 18 - 32 Vd.c. PM80 PM240 PSC240 PU500 PU1000
24 = 20 - 32 Vd.c. (*) PSE200, PSE250 PM500 PC1000
24T = 14.4 - 33.6 Vd.c. For train EN 50155/IEC 60571 and forklifts, on demand
24T = 12 - 40 Vd.c. For some train markets, on demand
28T = 16 - 40 Vd.c. MIL-STD 1275-D (28V) / ISO 7637-2 (24V), on demand


Polyamp guarantee full performance within the specified input range, which means 105% load capacity, 110% output voltage level at max rated operational temperature.
(*) Rated input voltage with max rating and temperature. The input accept <-35%  of nominal input before switching of the converter. The output can drop to 95% of nominal output.

An alternative in case you have cranking voltages use A input, see 12 V inputs.
An A input version has always slightly lower efficiency than above mentioned inputs.
