NOTE |
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. |
