CH1/CH2 Tracking Series Mode

Background

Tracking series operation doubles the Voltage
capacity of SPD-3606 by internally connecting
Channel1 (Master) and Channel2 (Slave) in serial
and combining the output to a single channel.
Channel1 (Master) controls the combined Voltage
output level.

The following describes two types of configuration
depending on the common ground usage.
