GENERAL DESCRIPTION
ELECTRICAL SPECIFICATIONS
All specifications valid at nominal input voltage, full load and +25C after warm-up time unless otherwise stated.
Our AM40U-C series is a family of cost effective 40W single output
DC-DC converters. These converters are shielded on all six sides and
encapsulated with a nickel-coated copper with a non-conductive base
and dimensions of 50.8x40.64x10.8mm. The high performance fea-
tures of our AM40U-C components include short circuit protection
with hiccup auto recovery, tight line regulation and a high efficiency
operation coefficient up to 88%.
Seven models operate from an input voltage of 48VDC
producing output voltages of 1.8, 2.5, 3.3, 5, 12, 15 &
24VDC. The normal operation is specified over the full
operating temperature range of -25C to +71C with no
derating required. Cooling is done by free air convection.
