With the widespread application of semiconductor lasers in fields such as industrial processing, medical equipment, and optical fiber communications, the performance testing requirements for their core component—the fiber laser—have become increasingly demanding. Fiber lasers, known for their lightweight design, high power output, and excellent stability, offer distinct advantages over semiconductor and solid-state lasers.

In energy storage systems, the testing and validation of the battery management system (BMS) is a crucial part. To ensure that the BMS can accurately collect voltage and current information and respond correctly under various complex battery states, it becomes especially important to simulate the behavior of the cells and packs. The IT2700 Multi-channel Modular Power System, with its powerful multi-channel serial and parallel capabilities, provides an ideal solution for energy storage BMS testing.

With the rapid development of battery technology, from consumer electronics to electric vehicles and large-scale energy storage systems, batteries have become the core energy carriers, making performance testing crucial. However, traditional battery testing methods — such as using real batteries or simple DC power supplies and electronic loads — often suffer from low efficiency, high cost, safety risks, and limited test scenarios.

Industry Background With the rapid development and widespread adoption of autonomous driving, trends such as the miniaturization, electrification, and chip-integration of LiDAR (Light Detection and Ranging) systems are gradually emerging. LiDAR is a laser-based detection and ranging system that uses a laser as the light source and employs optoelectronic detection techniques as an active remote sensing device.

EDDP refers to the total energy dissipated to produce a measurable and specific degradation indicator in the Device Under Test (DUT) during power cycling. It is an accelerated aging test method designed to evaluate the lifetime and reliability of power semiconductor modules under real operating conditions—such as frequent switching and load fluctuations.

In cutting-edge applications such as new energy, semiconductors, automotive electronics, and lasers, testing requirements are becoming increasingly complex. Traditional positive voltage power supply solutions can no longer meet the demands of chip bias testing, electrochemical deposition processes, operational amplifier power supply, and other applications requiring negative voltage and seamless positive-negative voltage switching. ITECH IT-N6300 Series triple-channel programmable DC power supply revolutionizes negative voltage power solutions with its built-in bipolar output mode. Without additional wiring, it enables efficient and stable negative voltage supply, significantly enhancing testing convenience, stability, and precision.
