This is a programmable DC regenerative power supply suitable for the evaluation of motors, inverters, converters, and more. It enables power regeneration and is an energy-saving power supply with minimal losses.

Head Spring is engaged in the development of advanced power electronics technologies, including the utilization of next-generation power semiconductors (SiC, GaN). The 'biATLAS' has been developed as a power supply device for evaluating and inspecting power generation and storage devices, as well as power conversion devices, in conjunction with the spread of electrification in automobiles and devices using renewable energy. "Power capacity: 5 kW, Output voltage: 0–525V, Supports up to 100 kW with 20 units connected." - Usage examples - ■ DC-DC converter evaluation ■ Power conditioner evaluation tests ■ Motor drive tests ■ Battery charging/discharging tests ■ Solar cell simulation and storage device simulation *For more details, please download the materials or contact us.

basic information

- Features - ■ Lightweight design with a weight of 18kg per unit for a device capacity of 5kW, making it easy to carry by one person. ■ A slim package with a height of 1.5U that can be mounted in a 19-inch rack, designed for equipment integration, with a high power density of 263W/ℓ. ■ Adoption of wide bandgap semiconductors and high-frequency switching technology achieves both miniaturization and high efficiency (conversion efficiency of 93%). ■ Supports bidirectional operation, allowing not only power output but also power absorption. The recovered energy is efficiently regenerated into the facility's power system and can be effectively utilized by other devices, creating an eco-friendly testing system. ■ By adopting the proprietary control technology Headspring Advanced Robust Control Technology (HARCT), it achieves both responsiveness and stability. It features a simple and intuitive operational design for easy setup. ■ Expansion of output voltage, output current, and output capacity is possible through direct parallel connection of outputs. *For more details, please download the materials or contact us.*
