Constant Power Mode (version 2.21 and higher)
In Constant Power Mode the power supply will continually adjust the
current levels to maintain a constant power set point. This mode is
intended primarily for loads with response time greater than
approximately 100ms. In order to provide additional protection for the
load, voltage and current limits may be set while in the constant power
mode. If the unit cannot regulate to the Constant Power setting due to
load conditions, it will regulate at either the voltage or the current limit
depending on the load demand.
Example, CP Mode:
Constant Power set 500W
Voltage limit 61V
Current limit 20A
To activate Constant Power mode and set the value:
3. Turn the 9-position mode control to the FLD position or press
the rotary Adjust/Enter control if the 9-position mode control
is already at the FLD position.
