Analog signal bandwidth is less than 100 Hz, supports any waveform within sig-
nal bandwidth. When the program signal frequency or amplitude exceeds output
capacity, the output amplitude will be automatically limited.
The definitions and descriptions for analog interface are as follows.

Type Description
Analog in Programs output voltage. Use an input voltage in the range
of 0 V to 10 V to control the output voltage in the range of 0
% to 100 %.
Analog out Current monitor signal. This pin generates a voltage of 0 V
to 10 V to monitor an output current of 0 V to the maximum
rated value. For example, if the maximum rated value is 60
A, and if the pin generates 2 V, the output voltage should be
approximately 12 A
Ground Ground for analog inputs and outputs.
- Not used
Digital in Receives the signal that is used to turn the output on or off.
If a 0 V signal is applied, the output is turned off. If a 5 V sig-
nal is applied, the output is turned on.
Digital out Sends the signal that is used to indicate whether the output
status is normal or not. If the power supply outputs normally,
the pin generates 5 V. If the power supply malfunctions, the
pin generates 0 V.
Digital out Sends the signal that is used to indicate the operation mode
of the power supply. When the power supply is in CC mode,
the pin generates 5 V. When the power supply is in CV
mode, the pin generates 0 V.
