(~8V, ~4.A, 18W) The -Series is a single output multi-range programmable switching DC Power Supply covering a power range up to 18W. This series of products include six models with the combination of 3V, 8V, and V rated voltages and 36W, 7W and 18W maximum output powers. The multi-range feature allows the flexible and efficient configuration of voltage and current within the rated power range. As the -Series can be connected in series for maximum units or in parallel for maximum 3 units, the capability of connecting multiple -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 -Series significantly reduces the user's cost for various power supply products to accommodate the projects with different power requirements. The C.V/C.C priority selection of the -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 -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 adjustable slew rate of the -Series allows user 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 capacitance 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 OVP and OCP protections are provided with the -Series. Both OVP and OCP levels can be selected within the range of 1% to 11%, with default level set at 11%, 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 -Series provides USB Host/Device and LAN interfaces as standard and GPIB- USB adaptor as optional. The LabView driver and the Data Logging PC software are supported on all the available interfaces. An analog control/monitoring is also available at the rear panel for external control of power On/Off and external monitoring of power output and. 8-7 (~8V, ~7A, 7W) PARALLEL OPERATION ( 3 UNITS ) MODEL SINGLE UNIT UNITS 3 UNITS V/3 3V/7A 3V/18A 8V/13.A 8V/7A 8V/4.A V/7.
