Power Supply
Choice of:
• 850W 88% Efficient wide-ranging, active Power Factor Correction
• 1125W 90% Efficient wide-ranging, active Power Factor Correction
NOTE:
The 1125W (1450W at 200V Input Voltage) power supply can also supply 1275W of output
power when the input voltage is greater than 105V. If the input voltage is less than 105V, but greater
than 90V for any reason, the maximum power that can be drawn is 1125W. An uninterruptible power
supply (UPS) is highly recommended if 1275W output power is desired.
The 1125W Power Supply can also supply 1450W of output power when the input voltage is greater
than 200V under all conditions.
