AC+DC Mode
The maximum power and current in the AC+DC mode is equal to that in the
DC mode
Current
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
Figure 2-3 and Figure 2-4. (Requires firmware revision 0.27 or higher.)
For MX30-3Pi model, constant power mode is supported at max ambient temperature.

voltage range
Current Limit mode
Programmable, CC or CV mode
Repetitive Peak Current
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 somewhat level 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.
