GENERAL DESCRIPTION
ELECTRICAL SPECIFICATIONS
All specifications valid at nominal input voltage, full load and +25C after warm-up time unless otherwise stated.
Our AM8TW-C series is a family of cost effective 8W
single and dual output DC-DC converters. These convert-
ers are shielded on all six sides and aluminum encapsu-
lated, have a non-conductive base and retain an anodized
black DIP24 compatible plastic case and dimensions of
31.8x20.3x10.2mm. The high performance features of
our AM8TW-C components include short circuit protec-
tion with current limit auto recovery, tight line regulation
and a high efficiency operation coefficient up to 82%.
These wide range devices operate over 4:1 input voltage
range, providing a continuously stable output voltage.
Sixteen models operate from an input voltage range of 24
& 48VDC producing output voltages of 3,3, 5, 12, 15, 24,
5, 12 & 15VDC. 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.
