The 4:1 input range covers 24V, 28V, or 48V nominal input voltages, and the trimmable output voltage options are 5V or 12V. The efficiency is particularly high Single Output (typically 92%) to permit full load operation from -40C up to +50C ambient temperature with only free air convection and up to 85C with forced air cooling. The isolation voltage is 1.5kVDC/1 minute (basic insulation grade). Applications include demanding industrial power supplies, telecom, and PoE circuits. 2 + RoHS REACH compliant compliant 10 from 10 Selection Guide Part Input Nom.
