PACKING  
1. All parameters are specified at normal input(12VDC,24VDC), rated load, 25℃ 70% RH ambient.  
2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf parallel capacitor.  
3. Output voltage will always step up by 3 Volts from input DC voltage.
