GENERAL DESCRIPTION
ELECTRICAL SPECIFICATIONS
All specifications valid at nominal input voltage, full load and +25°C after warm-up time unless otherwise stated.
Our AM20E-C series is a family of cost effective 20W 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 50.8x25.4x10.5mm. The high performance features
of our AM20E-C components include short circuit protection with current limit auto recovery, tight line regulation and a high efficiency
operation coefficient up to 88%.
Six models operate from an input voltage range of 24 &
48VDC then converts it into output voltages of 2.5, 3,3 &
5VDC. 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.
