GENERAL DESCRIPTION
Our AM20U-C series is a family of cost effective 20W single, dual
& triple 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 50.8x50.8x10.8mm. The
high performance features of our AM20U-C components include
short circuit protection with hiccup auto recovery, tight line regulation and a high efficiency operation coefficient up to 82%.
Thirty models operate from an input voltage range of 12,
24 & 48VDC producing single, dual or triple output voltages. The normal operation is specified over the full
operating temperature range of -25°C to +71°C with no
derating required. Cooling is done by free air convection.
