DC/DC Converters

MEAN WELL DC/DC converters change one DC voltage to another for battery systems, vehicles, telecom, railway and industrial equipment.

The range goes from sub-1 W on-board modules (DIP, SIP and SMD packages) up to about 1 kW enclosed units. Common inputs are 9–18 V, 18–36 V, 36–72 V and ultra-wide 9–75 V or 150–1,500 VDC for PV systems; outputs from 3.3 V to 54 V. Families include enclosed SD and RSD/RSDH railway and PV models, DIN rail DDR/DDRH, PCB-type PSD and on-board isolated and non-isolated modules.

Check isolation (VDC), input range and package before ordering. See also MEAN WELL power supplies in the USA.

Ships from Miami, FL. Tariffs included in our prices, and in-stock orders placed before 4:00 PM ET ship the same business day.
