MPS Droop Characteristics - All Ouput Voltages
The MPS output voltage is semi-regulated. As the output current increases, the output
voltage will decrease. Typically, the output voltage will decrease by 10% at full load.
Note that the full rated output power of 4000 W can be derived from the AC INPUT having a
voltage within this uncommon range for up to 15 seconds before the MPS will shutdown its
output. Also note that the MPS can drive at full rated power for a 2 second interval even if
the AC INPUT voltage drops below 100 V
