| Notes & safety | |
| Notes: | 1. To indicate “A” type pinning, add –A suffix to model number. Ex. MRW20-24S05-A To indicate heatsink, add –H suffix to model number. Ex. MRW20-24S05-H To indicate both “A” type pinning and Heatsink, add –AH to model number. Ex. MRW20-24S05-AH 2. To meet EN61000-4-4 & EN61000-4-5 an external capacitor across the input pins is required. Suggested Capacitors: 24V Input Models: CHEMI-CON KY Series 390µF/63V 48V Input Models: CHEMI-CON KY Series 330µF/100V 110V Input Models: CHEMI-CON KXJ Series 390µF/200V 3. Other input and output voltages may be available, please contact factory. 4. It is recommended to protect the converter by a slow blow fuse in the input supply line. *Due to advances in technology, specifications subject to change without notice. |
