Parallel Operation and Series Operation
Overview of Series Operation
CH1 and CH2 can be connected in series inside the product to double the voltage output range. CH2 oper-
ates as the master channel and CH1 as the slave channel.
In series operation, the output voltage is the total of the CH1 and CH2 outputs.
Series operation functions
Voltage display and current display
The voltage or current is displayed on CH2 (master). The voltage is the total voltage of CH1 and CH2. The
CH1 voltmeter shows “
SLAVE
.”
Remote sensing
This is available
.
The specifications of this product are defined with the premise that CH1 and CH2 are con-
nected in series internally. When used as positive and negative power supplies, the specifi-
cations may not be met.
The current limit of the CH1 output terminal and that of CH2 (master) are different.
Panel display during series operation
Example when the output voltage is 60 V (CH1: 30 V+CH2: 30 V)
and the output current is 3 A

CAUTION
The wiring for sensing is complicated when using remote sensing during series operation.
Be careful to wire the cables correctly. Incorrect wiring can cause abnormal voltage output or
damage to the product.
