GENERAL DESCRIPTION
ELECTRICAL SPECIFICATIONS
All specifications valid at nominal input voltage, full load and +25°C after warm-up time unless otherwise stated.
Our AM30K-I series is a family of cost effective 30W 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 features of our AM30K-I components include continuous short circuit protection with auto recovery , tight line regulation
and a high efficiency operation coefficient up to 88%.
Twenty one models operate from an input voltage of 12,
24 & 48VDC producing output voltages of 3.3, 5, 12, 15,
±5, ±12, & ±15VDC. The normal operation is specified
over the full operating temperature range of -40°C to
+75°C with no derating required. Cooling is done by free
air convection.
