Alternate power supply for CCR1036-12G-4S

Hi,
may be anyone know the range of power voltage of CCR1036-12G-4S ? I want to replace the standart PSU to battery support PSU.
The standart PSU give 24.2Volts. Can i use 27-56Volt psu for this routerboard as i do with RB800?

18-28V is supported by CCR 36 core model

What about 1016?

same as ccr1036

PSU in my CCR1036 died, is there any shop that will sell separate PSU for it?
