Teledyne LeCroy T3PS100011P 0-100V High-Precision DC Power Supply

The new T3PS series are single-output multi-range programmable switching DC Power Supplies covering a power range up to 720 W. This series of products offers five models with rated voltages of 30 V, 80 V, 160 V, 250 V and 800 V and 360 W and 720 W maximum output powers. The multi-range feature allows for a flexible and efficient configuration of voltage and current within the rated power range. A maximum of two units in series and a maximum of three units in parallel can be connected for applications requiring Voltage/Current higher than the rated output. The combination of multi-range power output feature and series/parallel operation capability of T3PS series significantly reduces the cost by accommodating the projects with wide range of power requirements.

The C.V/C.C priority selection of the T3PS 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-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 T3PS supply is capable of operating under C.C priority to limit the current spike occurred at the threshold voltage and protects DUT from the inrush current damage.

The adjustable slew rate of the PSW-Series allows users to set a specific rise/fall time for signal transitions of either output voltage or output current. The adjustable slew rate feature is useful in manufacturing tests of lighting where a 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 currentintensive 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 T3PS series offers OVP and OCP. 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 disabled to protect the DUT. The T3PS provides USB Host/Device and LAN interfaces as standard. 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.
