NOTE | 1. All parameters are specified at normal input (48VDC), rated load, 25°C 70% RH ambient. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12” twisted pair terminated with a 0.1uf capacitor. 3. Test condition: 48VDC input. 4. Output voltage will always step down by 3 volts from input DC voltage. |
