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 ponents 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.
