Features
•
•
•
•
•
Low cost (low component count with single sided printed circuit board)
Low conducted EMI: meets CISPR22B/EN55022B without requiring a Y capacitor
Meets EN/UL 1000-4-5 CLASS 4 (4 kV), using line overvoltage protection feature
Designed to IEC60950 safety standard requirements
Ultra-low earth leakage current (<1 µA @ 265 VAC, 50/60 Hz) eliminates line frequency audio
hum in voice applications (“ground loops”)
•
•
•
•
•
Compact Design (L = 113 mm, W = 39 mm, H = 25 mm)
High efficiency (≥70% at 85 VAC)
Line undervoltage shutdown prevents turn-off output glitches
Line overvoltage shutdown provides extended line swell protection
Hysteretic thermal shutdown provides automatic supply recovery after fault removal
