Is used mainly on trains, in power plants and sub-sta­tion applications. High immunity levels are required.
Use the D input (90-270V) or 110 (93-150V).
For EN50155, IEC60571 train standards use our C-input (50-150V) or 110T (66 – 154V).


Input range Family codes
C = 50 - 150 Vd.c. PM50 PSE100 PSC150 PM150 PM260 PU300 PU600
D = 90 - 270 Vd.c. PM50 PSE100 PSC150 PM150 PM260 PU300 PU600
110 = 88 - 150 Vd.c. PM80 PM240 PSC240 PU500 PU1000
110 = 93 - 150 Vd.c. (*) PSE200, PSE250 PM500 PC1000, PC1400, PC2000
110T = 66 – 154 Vd.c. For train EN 50155/IEC 60571 and forklifts, on demand
 110T = 50 – 160 Vd.c. For some train markets, 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.
