In scientific research experiments such as photocatalysis, water splitting for hydrogen production, photovoltaic spectral response testing, material photolysis, and fluorescence spectral characterization, the 150W short-arc xenon lamp is the core light source for simulating sunlight. The xenon lamp has a continuous spectrum covering ultraviolet, visible to near-infrared, and its color temperature is close to natural sunlight. However, whether the entire light source system can provide stable and reproducible lighting conditions is determined by the xenon lamp power supply.

Many researchers will encounter these problems: it is difficult to ignite the xenon lamp and the triggering is unstable; during long-term light exposure experiments, the source flickers and the light intensity drifts; the impact current at startup damages the xenon lamp, and the lamp tubes require frequent replacement; fluctuations in the grid voltage directly transmit to the light source, causing the data of multiple parallel experiments to be discrepant, and a large amount of samples, reagents, and experimental time are wasted.

Sevan Optoelectronics' 7IPX150B, a digital xenon lamp power supply specifically developed for 150W short-arc xenon lamps, is compatible with the 7ILX150 series xenon light source chamber, providing high-precision controllable constant current drive for scientific xenon lamps, solving the pain points of difficult startup, unstable operation, and easy lamp burnout of xenon lamps, making the simulated sunlight output stable and controllable, and ensuring the consistency of experimental data.

The 7IPX150B is equipped with a digital constant current control scheme, ensuring precise and controllable output current, effectively suppressing current ripple, maintaining stable light intensity during long-term continuous operation, and reducing system errors caused by lamp drift. The power supply is equipped with an intelligent soft start trigger mechanism, smoothly initiating the xenon lamp ignition, avoiding surge impacts during cold start-up, protecting the xenon lamp electrodes, effectively extending the lamp tube service life, and reducing long-term laboratory consumables costs.

The entire machine is equipped with a nine-layer safety protection system, covering overvoltage, overcurrent, overheating, short circuit, open circuit, lamp trigger failure, fan failure, etc. Once an abnormal condition is detected, the output is cut off within milliseconds to prevent the expensive xenon lamp and optical equipment from being burned out, ensuring the safety of the laboratory personnel. After shutdown, the power supply is accompanied by delayed air cooling, continuously dissipating heat from the light source chamber, further protecting the entire set of light source components and extending the equipment's service life.

As a digital model, the 7IPX150B supports precise panel parameter adjustment, allowing for the adjustment of output power as needed, flexible changes in irradiation intensity, and easy setup of experiments with different light intensity gradients. The standardized interface design enables seamless integration with SpectraView monochromators, sample chambers, filter wheels, PMT detectors, and other optical components. It can quickly set up a complete spectral testing optical path and is suitable for various optical experimental platforms in universities, research institutes, and enterprise R&D centers.

The applicable scenarios cover directions such as photocatalytic pollutant degradation, photolysis water production for hydrogen, solar cell spectral response testing, thin film optical characterization, material photo-aging acceleration experiments, fluorescence and UV-Visible spectral detection, etc.

This domestic research optical instrument solution takes into account performance, delivery cycle, and after-sales support. The SpectraView 7IPX150B xenon lamp power supply, with stable and reliable digital drive, reduces interference from power supply variables, allowing each simulated sunlight experiment to be repeatable and traceable, and providing support for research work in materials, photochemistry, and new energy fields.
