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)
