PRODUCT OVERVIEW

The new 1.2, 1.5V, 1.8V and 2.5V models in

Murata Power Solution's flagship 7-15 Watt

A-Series can source a continuous 6 Amps. This

is the most "low-voltage" current available from

a standard 1" x 2" package, and these power

converters exemplify C&D’s relentless drive to

bring you more power/current, from standard

packages, without compromising reliability or

resorting to thermal specmanship.

UWR Models are able to bring you 7-15W (@

up to 6A) in the standard 1" x 2" package from

which most competitors can only get 5-10W (@

3-4A). All UWR’s deliver their full output power

over ambient temperature ranges from –40°C

to as high as +70°C (model and input voltage

(D12 models), 18-36V (D24 models) or 36-75V

(D48 models). All models feature input pi filters,

input undervoltage and overvoltage lockout, input

reverse-polarity protection, output overvoltage

protection, output current limiting, and continuous

short-circuit protection. On/off control and output-

trim functions are optional (see Optional Func-

and EN60950-1 safety requirements. D48 models

(36-75V inputs) are CE marked.
