REV.: 0/2015 www.recom-international.com
Notes:
Note1: An external input filter capacitor is required if the model has to meet EN61000-4-4 or/and EN61000-4-5.
Recommended components: 5Vin aluminium capacitor (Nippon Chemi-con KY series, 1000µF/25V) and a
reverse diode (Vishay V10P45) to connect in parallel
12Vin, 24Vin aluminium capacitor (Nippon Chemi-con KY series, 470µF/50V)
48Vin aluminium capacitor (Nippon Chemi-con KY series, 330µF/100V)
Note2: The REM3 (W) with 4:1 input voltage can meet EMI Class A with no external filter. And Class B only with external components.
Note3: This Power module is not internally fused. A input line fuse must be always used.
