One-Control Parallel Operation; Overview Of One-Control Parallel Operation - TEXIO PSW-A Series Instruction Manual

To help to minimize the oscillation due to
the inductance and capacitance of the
load cables, use an electrolytic capacitor
in parallel with the load terminals.
To minimize the effect of load line
impedance, use twisted wire pairing.

2.3. One-control parallel operation

This section describes the basic operations required to operate the power
supply in parallel. Operating this product in parallel increases the total
power output of the power supply units.
The number of the power supplies that can be connected in parallel
depends on the model and the mode.
Parallel operation: 3 units maximum
To use this product in parallel, units must be used in a Master-Slave
configuration. In the master-slave configuration a "master" power supply
controls any other connected "slave" power supplies.

2.3.1. Overview of one-control parallel operation

One-control parallel operation of this product is possible for up to three of
the same models. There are some precautions and limitations when using
this machine in parallel. Please read this overview carefully before starting
parallel operation of this product.

Description
Only the master unit will display voltage and
current. The current value is added and displayed.
OVP/OCP detection is performed on the master
unit. The OVP/OCP function of the slave unit is
disabled.
When the master unit detects OVP/OCP, the output
is turned off, and at the same time, the output of the
slave unit is also turned off.
(IMON) can only be used on the master unit.
The current monitor (IMON) signal represents the
total current of all products connected in parallel.
Remote sensing function can be used.
