NOTES
BELLCORE TR-NWT-000332. Case Stress, Temperature (Ground fixed controlled environment) Maximum value nominal input voltage full load standard type. Typical value nominal input voltage load. Typical value nominal input voltage full load. Test minimum constant resistive load. ON/OFF control voltage referenced -Vin. order positive logic ON-OFF control suffix (Ex: KR48S5-1000P) order negative logic ON-OFF control suffix (Ex: KR48S5-1000R) industrial suffix input version more efficient; therefore, operated more extensive temperature range than "standard" suffix input versions. order industrial temperature range (-40°C +85°C) suffix part number (Ex: KR48S5-1000I) Heat sink optional, consult factory. external filter capacitor required module meet EN61000-4-5. filter capacitor Wall Industries suggests: Nippon chemi-con Series 220uF/100V 48m.
