Document
Number EPR-000013
Date 08-May-2001
Revision 1.0
Features
• Compact Design (6.875” L X 2.56” W X 1.56” H)
• 43 W steady state output power at 50 °C ambient, free convection
• High efficiency (75% minimum at 180 VAC input, maximum continuous load)
• Low no-load power consumption (< 0.7 W @ 180 VAC, < 0.8 W @ 265 VAC)
• Multiple section transformer for low cost automated production
• Excellent output voltage tracking and cross regulation
• Primary soft-start minimizes component stress during start-up
• Low conducted EMI due to frequency jittering: meets CISPR22B/EN55022B
• Line overvoltage shutdown provides extended line surge protection
• Hysteretic thermal shutdown allows automatic supply recovery after fault removal
• Low component count with single sided printed circuit board
• Surge immunity up to 4 kV (surge or 100 kHz ring wave)
