Functions and Features

4.4 Channel Parallel Function (Parallel)

Parallel in the System menu supports connect the two channels of a single IT-

M3100D in parallel, the upper limit of the current setting range is twice the rated

value of the single channel, and the instrument is used as a single channel

power supply at this time.

Parallel configuration of 2 or more IT-M3100Ds is not supported.

After parallel combination, it is operated as a single instrument. The initial set-

tings of each function menu and voltage, current and power are based on the

following rules:

• Config menu: After Parallel, the CC/CV priority, on/off delay, Sense switch,

and trigger mode in the Config menu refer to the settings of CH1, and the

rise/fall time in the Config menu refers to the slowest slope setting of the two

channels. After switching back to single, both channels refer to Parallel

settings.

• Voltage/Current/Power setting: After Parallel, V-set is the smaller value of

the two-channel voltage. I-set is the sum of the current settings of the two

channels. P-set is twice the power set value of CH1. When switching back to

single, the current and power setting values of the two channels are half of

the corresponding setting of Parallel, and the voltage is the corresponding

voltage in Parallel mode.

• PROTECT menu: After Parallel, the default is the parameters of CH1 chan-

nel. When switching back to single, the two channels are Parallel

parameters.

– OPP: After Parallel, the setting value is the sum of the OPP setting values of

the two channels. When switching back to single, it is half of Parallel OPP.

– OCP: After Parallel, OCP defaults to the sum of the OCP current settings of

the two channels. When switching back to single, the OCP of the two chan-

nels is half of Parallel.

• Foldback protection: When the Foldback settings of the two channels are

the same, after combining, the default is the setting of CH1. When the Fold-

back settings of the two channels are different, the Foldback will be turned

off after Parallel. When switching back to single, the settings of the two chan-

nels are the same as those of Parallel.

• Save/Recall: When it is Single, after the two channels execute save and

Parallel respectively, the recall voltage value is the CH1 voltage value, and

the current is the sum of the current values of the two channels. When it is
