6991 In Stock

The 6991 by Newport is a specialized Arc Lamp Power Supply designed to efficiently power Mercury/Xenon and Xenon lamps in light source kits with a maximum capacity of 500 W. Engineered for stability and reliability, this power supply ensures a consistent light output and operates with high precision. For applications requiring exceptional stability and extended use, the power supply is best complemented by the implementation of a Digital Exposure System. The Exposure System serves to compensate for factors beyond the power supply's capabilities, such as gas absorption, electrode erosion, and lamp aging. By incorporating this system, optimal performance can be achieved. Equipped with an RS-232 computer interface, the 6991 facilitates remote control functionality. Users can remotely power the unit on or off, monitor light output levels, and configure lamp operating parameters.

The 6991 has a start/stop control feature that enables the lamp to be ignited at predefined values, effectively minimizing overshoot or undershoot of operating current. Primarily designed to cater to the regulated power or current requirements of high-power ARC light sources, the power supply is ideal for applications demanding stable light output or precise radiometric measurements. Its capability to provide constant power/current operation for radiation sources ensures dependable performance in critical scenarios. Notable features of the 6991 include an adjustable output, intuitive LED indicators that convey crucial power supply functions' status, and a remote I/O connector enabling remote metering and direct compatibility with Digital Exposure System models. The digital display allows accurate monitoring of current, voltage, power, and lamp running time, enhancing control and management. Additionally, the power supply incorporates a safety interlock connector, safeguarding against accidental exposure to UV light when used with a compatible lamp housing.
