The PRP-Series is a single-output multi-range programmable switching DC Power Supply covering a power range up to 400W. This series of products include two models with the combination of 20V rated voltages and 200W, 400W maximum output powers. As the PRP-Series can be connected in series for maximum 2 units or in parallel for maximum 3 units, the capability of connecting multiple PRP units for higher voltage or higher current output provides a broadcoverage of applications.
The CV/CC priority selection of the PRP-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-onstage,the PRP-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.
The adjustable slew rate of the PRP-Series allows user to set for either output voltage or output current a specific rise time at the low to high level transition, and a specific fall time at the high to low level transition. This facilitates the characteristic verification of a DUT during voltage or current level changes with controllable slew rates. The manufacturing tests of lighting device or large capacitor during power output-on are mostly associatedwith 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 are provided with the PRP-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 level is tripped, the power output will be switched off to protect the DUT. The PRP-Series provides RS-232/RS-485 interfaces as standard. An analog control/monitoring connector is also available on the rear panel for external control of power On/Offand external monitoring of power output Voltage and Current.
