Is used mainly in power plants and sub-station applica­tions. High immunity levels are required. Use the D input code  or 220. The 250V battery is not very common but can only be used with 220 inputs. Hy­bride cars and submarines uses similar voltages, please contact us.


Input range Family codes
D = 90 - 270 Vd.c. PM50 PSE100 PSC150 PM150 PM260 PU300 PU600
220 = 175 - 300 Vd.c. PM80 PM240 PSC240 PU500 PU1000
220 = 187 - 300 Vd.c. (*) PSE200, PSE250 PM500 PC1000, PC1400, PC2000

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.
