The family consists of eight standard models offering input ranges of 18 to 75 Vdc and 43 to 160 Vdc and output voltages of 12, 24, 28, and 48 Vdc. The 300W chassis mount dc/dc converters are fully potted in a sealed metal case that has been qualified for resistance against shock and vibration in industrial and railway environments per EN 61373 and MIL-STD-810F. Their high efficiency and heatsink design allow for convection-cooled operation of -40°C to +80°C (up to +55°C without derating). Features include: high efficiency operation up to 92%; I/O isolation of 3,000 VDC; under voltage lockout; protection against over-voltage / over-temperature / short circuit; and an input filter to meet EN 55022 & EN 55011 class A conducted. Status and control features include remote on/off, remote sense and active current share. These converters measure a mere 6.00 x 4.00 x 1.52”. All models are safety approved to IEC/EN/UL 60950-1, EN 50155, UL 508, CB test report and bear the CE Mark with a warranty of 3 Years.
