Voltage inverters are intended to convert DC voltage to AC voltage. They can be used at facilities where there is a backup rechargeable battery or an external DC source of the required voltage.
DC voltage converters are intended to supply stable power to communication and telecommunication equipment, security systems, as well as to industrial equipment with nominal DC voltage of 12, 24, 60 V, when operating from a DC source with a nominal voltage of 48 or 60V.
