Multi-Range Programmable Switching D.C. Power Supply GW Instek PSW80-27

The GW Instek PSW80-27 is a Multi-Range Programmable Switching D.C. Power Supply that offers a flexible and efficient configuration of voltage and current within the rated power range. With a voltage rating of 80V and an output power rating of 720W, this power supply is a great choice for a wide range of applications. The PSW-Series is designed to be a single-output multi-range programmable switching DC Power Supply, with a total of 15 models available with a combination of 30V, 80V, 160V, 250V and 800V rated voltages and 360W, 720W and 1080W maximum output powers. This allows for a versatile and efficient power supply that can be used for a variety of projects with different power requirements, without having to purchase multiple power supplies.

The multi-range feature allows for the flexible and efficient configuration of voltage and current within the rated power range. This means that you can easily adjust the voltage and current settings to match the requirements of your project, without having to purchase multiple power supplies. Additionally, the PSW-Series can be connected in series for maximum 2 units or in parallel for maximum 3 units, providing a broad coverage of applications. This means that you can easily connect multiple units together to increase the voltage or current output, providing even more versatility and flexibility in your power supply options.

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 can bring a high inrush current to the capacitive load or current-intensive load at the power output-on stage. However, with the PSW-Series, it 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. This is particularly useful for the battery and LED industry, as it helps to protect your devices from damage due to inrush current.

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 PSW-Series also provides OVP and OCP protection to protect the DUT. 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. This added protection feature helps to ensure the longevity and safety of your devices.

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. This makes it easy to connect and monitor the power supply, and to control the power output.
