RATED POWER
1. All parameters are specified at normal input(12VDC,24VDC), rated load, 25 70% RH ambient.℃
2. (Blank) type and W type output voltage must step up by 3 Volts from input DC voltage;
(Blank)DA type and WDA type output voltage must step up by 12 Volts from input DC voltage.
3. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf parallel capacitor.
