Figure 8.2 External Series Circuit

Operation Procedures:

1. Connect the power supply to load as shown in the figure above. Pay attention to

the polarity when making connections.

2. Set proper voltage, current, and over-current protection value for each channel

(refer to

Constant Voltage Output

) and turn on the channel outputs. All the

channels connected in series should be set to CV mode and have identical current

setting value and OCP value.

CAUTION

Please make sure that all the channels connected in series operate in CV mode. One of the

channels operating in CC mode can cause unregulated output mode for the other

channels.

8.2 Parallel Connections

Connecting outputs in parallel provides a greater current capability than can be

obtained from a single output. The total current is the sum of the individual currents

of all channels connected in parallel. To connect outputs in parallel externally, you

need to ensure identical voltage value and OVP value for each channel.

Internal Parallel Connections

This series power supply supports internal parallel connection for CH1 and CH2. In

internal parallel connection mode, the output current (up to 6 A) is twice the current

setting. The output voltage and current are displayed in CH1 meter view, as is shown

in the figure below.
