These devices each have a primary +5V output
that can source from Amp to .5 Amps (model
dependent) and auxiliary ±2/5V outputs that can
source from ±50 to ±250mA (model dependent).
All models can simultaneously source maximum
rated current from both primary and auxiliary
outputs. The nominal input voltage for each model
is 48V.
As members of C&D’s new A-Series, the 2-5W
triples exhibit both low cost and outstanding long-
term reliability. Their design combines straight-
forward circuit topologies, proven SMT-on-pcb
construction methods, the newest components, and
highly repeatable automatic-assembly techniques.
The A-Series TWR’s superior durability is substanti-
ated by a rigorous in-house qualification program
that includes HALT (Highly-Accelerated Life Testing),
which is designed to detect any potential electrical,
mechanical or process weakness.
Packaged in standard, 2" x 2" x 0.45", shielded
metal cases with non-conductive coatings, these
fully isolated (000Vdc minimum) DC/DC’s offer
excellent line and load regulation. Additionally,
these A-Series triples have non-latching output
current limiting, input overvoltage shutdown, input
reverse-polarity protection, and output overvoltage
clamping to protect both the power converters and
their loads. All A-Series TWR models are fully EMI
characterized and designed to meet UL950, IEC
950, CSA 950 and EN60950.
SIMPLIFIED SCHEMATIC
Featuring C&D’s ultra-wide, 8-72V, input voltage range, this Family of
A-Series, TWR (triple-output) DC/DC converters deliver up to 5 Watts.
