APPLICATION
Add suffix “H” for heatsink mounted, for example URB2405LD-20WH.
The URB_LD-20W series offer 20W of output,
with 4:1 ultra wide input voltage of 9-36VDC,
18-75VDC, and features 1500VDC isolation,
over current, over voltage and short-circuit
protection, as well as six sided metal shielding.
All models are particularly suited to industrial,
tele-communications, test equipments power.
