3 times output power rating
A wide range of voltage and current settings
can be combined within its output power rating
(3 times).
For example, the output power of 1500 W
model, the PWX1500ML is capable to operate
seamlessly from the range of "80 V-18.75 A" to
"26.8 V-56 A".
The operating range can be varied the ratio of 3 times within its output power rating with a full range of functions that make it suitable as a test power supply

Practical convenient functions are
equipped as standard features.
l
Bleeder on/off function
The capacitor is connected to the output end of the PWX series,
and the bleeder circuit is equipped to discharge the electric
charge when the OUTPUT is OFF. For example, when the
battery is connected to the output terminal, even if it is in the
state of OUTPUT OFF, when the bleeder circuit is set to ON,
the bleeder circuit will discharge electric charges of the battery.
In this case, excessive electric discharge can be prevented by
setting the bleeder circuit to OFF state. It is possible to omit the
diode for reverse current prevention required for the charge of
such a battery.
l
A startup state setup at the time of output ON
You can set for the priority operation mode (CC (constant
current) priority/CV (constant voltage) ) when the output is turned
ON. It prevents the overshooting when the output is turned ON.
l
Preset memory function
The preset memory function allows you to save up to three
combination of each preset value of voltage, current, OVP, OCP,
and UVL. The saved preset value can be called from the preset
memory on the front panel.

Series Operation
You can connect up to two units in series. The total of the output
voltages of the two units is applied to the load. The voltage setting
accuracy is the same as the accuracy of an individual unit.
*You cannot perform master-slave configuration in series
operation.
l
Master-Slave Parallel Operation
In master-slave parallel operation, one unit is the master unit, and
all other units connected in parallel are slave units. The master
and slave units must all be the same model. You can control
the whole system by operating the master. You can use master-
slave parallel operation to increase the output current (maximum
output current: the rated output current of one unit × the number
of units connected in parallel). You can connect up to four units,
