• Screw terminals for inputs and outputs
• Wide operating input voltage 90 – 264VAC, 47 – 63Hz
• Excellent output regulation from no load to full load
• High efficiency
• Overload and short circuit protection
• Inbuilt EMI filter to reduce noise radiation
• EMC approved

Input:
Input range: 90-264V AC
Frequency: 47-63Hz
