LOWER COST
75W 100W 150W
Now you don't have to give up reliability, features or support to meet your bill of material cost targets. Kepco's Series JBW are
low cost 5V, 12V, 15V and 24V power supplies priced at about $.50 per watt, even in sample quantities. They are reliable PC card-
style single output power supplies offering OEMs 75, 100 and 150 watts of d-c power. JBW feature wide range input (85-265V a-c),
active PFC (Power Factor Correction) and carry the CE Mark and all safety agency recognitions, plus they are RoHS compliant. The JBW
power supplies have on-board filtering meeting FCC Class B conducted emissions compliance and feature overvoltage and overcurrent
protection. Full output power operation is guaranteed from -10 to + 50°C with convection cooling. (No forced air cooling is required.)
The JBW series comes with a full 1 year warranty supported by Kepco, a name known and trusted in the power supply
industry for 60 years.
Please visit www.kepcopower.com/jbw.htm to check out the full specifications of our new JBW models as well as
our lower power JBW 10, 15, 30 and 50W models and order a sample unit on-line. To see full specifications on our related
multi-output MTW series of 15, 30 and 60W power supplies, visit www.kepcopower.com/mtw.htm
or give us or your local representative a call. We look forward to hearing from you. RoHS Compliant
