Description
The PSW-Series is a single-output multi-range programmable switching
DC Power Supply covering a power range up to 1080W.
This series of products include eighteen models with the combination
of 30V, 40V, 80V, 160V, 250V, and 800V rated voltages and 360W, 720W and 1080W maximum output
powers. The multi-range feature allows the flexible and
efficient configuration of voltage and current within the rated
power range.
As the PSW-Series can be connected in series for maximum 2 units or
in parallel for maximum 3 units, the capability of connecting multiple PSW units for higher voltage
or higher current output provides a broad coverage of applications.
With the flexibility of multi-range power utilization and
series/parallel connection, the PSW Series significantly reduces
the user’s investment for various power supply products to
accommodate the projects with different power requirements.
The CV/CC priority selection of the PSW-Series is a very useful
feature for DUT protection. The conventional power supply
normally operates under CV mode when the power output is turned on.
This could bring a high inrush current to the capacitive
load or current-intensive load at the power output-on stage. Taking
the I-V curve verification of LED as an example,
it becomes a very challenging task to perform this measurement using
a conventional power supply. With LED connected to a power
supply under CV mode as the initial setting, when the power output
is turned on and the voltage rises to the LED forward voltage,
the current will suddenly peak up and exceed the preset value of
current limit. Upon detecting this high current, the power supply
starts the transition from CV mode to CC mode.

Though the current becomes stable after the CC mode is activated,
the current spike occurred at the CV and CC crossover point may
possibly damage the DUT. At the power output-on stage, the
PSW-Series is able to run under CC priority to limit the current
spike occurred at the threshold voltage and therefore protect DUT from the
inrush current damage.
