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 fifteen models with the combination of 30V,
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-Series 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 users’ cost for
various power supply products to accommodate the projects with different power requirements.
The adjustable slew rate of the PSW-Series allows users to set for either output voltage or output
current, a specific rise time from low to high level transition, and a specific fall time from high to low
level transition. This facilitates the characteristic verification of a DUT during voltage or current level
changes with controllable slew rates. Most manufacturing tests of lighting device or large capacitor
during power output-on are associated with the occurrence of high surge current, which can greatly
reduce the life time of the DUT. To prevent inrush current from damaging current-intensive devices,
a smooth and slow voltage transition during power On-Off can significantly reduce the spike current
and protect the device from high current damage.
The C.V/C.C priority selection of the PSW-Series is a very useful feature for DUT protection. The
conventional power supply normally operates under C.V 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 C.V 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 C.V mode to C.C
mode. Though the current becomes stable after the C.C mode being activated, the current spike
occurred at the C.V and C.C crossover point may possibly damage the DUT. At the power output-on
stage, the PSW-Series is able to operate under C.C priority to limit the current spike occurred at the
threshold voltage and therefore protects DUT from the inrush current damage.
The OVP and OCP are provided with the PSW-Series. Both OVP and OCP levels can be selected,
with default level set at 110%, of the rated voltage/current of the power supply. When any of the
protection levels is tripped, the power output will be switched off to protect the DUT. The PSW-Series
provides USB Host/Device and LAN interfaces as standard, GPIB-USB adapter and RS232-USB cable
as optional. The LabView driver and the Data Logging PC software are supported on all the available
interfaces. An analog control/monitoring connector is also available on the rear panel for external
control of power On/Off and external monitoring of power output Voltage and Current.
