Power (total power for all phases, either range, at full scale voltage, maximum ambient T = 35° C)
AC Mo d e 22.5 KVA 3 0 KVA 4 5 KVA
DC Mo d e 1 5 KVA 20 KW 30 KW
AC+DC Mod e
The maximum power and current in the AC+DC mode are equal to that in the DC mode
NOTE: Current, maximum amps indicated per phase available between 50 and 100 % of voltage range. Maximum ambient temperate for full power
operation at full-scale voltage is 35° C.
Constant Power Mode:
Operation at higher currents but constant power is possible from 80% of Voltage range (125% of max. current) declining to 100% of maximum current
at 100 % of voltage range for short periods of time or at reduced ambient temperatures. (< 15 mins @ 30° C). See Fig u r e 2-1 (Requires firmware
revision 0.27 or higher.).
NOTE: Fo r MX3 0 -3Pi model, constant power mode is supported at max ambient temperature

NOTE: Current derates linearly from 50% of voltage range to 20% of specified current at 5% of voltage range
Current Limit mode P r o g r a m m a b l e , CC o r CV m o d e
NOTE: Maximum Peak Current shown. Value shown reflects absolute peak current protection level. This level may not be reached under all load
conditions. Depending on load conditions, peak current may max out at lower levels due to amplifier output impedance.
NOTE: As of firmware revision 4.52, a repetitive peak current limit function is provided which will generate a fault and shut off the power supply if
the peak current drawn by the load exceeds the maximum level for more than 30 seconds. During this time, the amplifier will limit the peak
current at a level somewhat above the maximum level, but it is not allowable to run in this mode indefinitely. This should provide sufficient
time to ride through any startup/ inrush load conditions.
