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
