The Instek PSW-720L22 is a dual-channel, wide range output, programmable switching DC power supply. The maximum power is 720W. Channel one and channel two are rated for 40V output voltage and 27A output current.

The PSW-Multi series includes 37 models including 13 dual-channel models with a rated power of 720W, and 24 triple-channel models with a rated power of 1080W. The rated voltages of low voltage modules are 30V, 40V, 80V, 160V. The rated voltages of high voltage modules are 250V and 800V. 

The advanced web server, a unique function of the PSW-Multi series, can directly execute SCPI commands on the server and control the PSW-Multi power supply. The data log has an interval of 1 second. It can edit output sequence.

The PSW-Multi series modules provide CC Mode and CV Mode to fit a range of applications in the general-purpose market. For critical applications with more specific requirements, the CC and CV priority selection feature enable the power supply to run under CC priority rather than normal CV priority at the output-on stage.

The PSW-Multi series has adjustable slew rates for the level transition of both current and voltage. This gives the PSW-Multi power supply the ability to set specific rise time and fall time of the voltage and current drawn from the power supply to verity DUT performance during the voltage/current level transition. The feature also slows down the voltage transition at the power output-on to protect DUT from inrush current damage. This feature is especially useful for the test of heavy-current-drawn devices like capacitors.

The PSW-Multi series employs a bleed resistor in parallel with the output terminal. The bleed resistor is designed to dissipate the power from the power supply filter capacitors when power is turned off and the load is disconnected. Without a bleed resistor, the power terminal may remain charged on the filter capacitors for some time and be potentially hazardous. In addition, the bleed resistor acts as a minimum voltage load. The bleed resistance can be turned on or off using the configuration setting.

The PSW-Multi series provides a USB host port in the front panel for easy access of stored data, such as test script program. In the rear panel, a USB device port is available for remote control or I and V data logging of power output through a PC controller. The LAN interface, which meets DHCP standard, is provided as a standard feature for system communications and ATE applications. Optional extender terminal box accessories (sold separately) can be used to extend the power output from the rear panel to the front side. This provides convenience to do the job without frequently having to reach the output terminal at the rear of the device.
