While utilizing the specifications and data of our DC regenerative power supply 'biATLAS-D', we have organized what exactly a "DC regenerative power supply" is. A DC regenerative power supply can both supply and consume power, and it is also capable of "regeneration" back to the power system. Furthermore, it is a somewhat ambitious and eco-friendly device that can be used in various applications. On our website, we provide detailed information about the "operating range" and "size" of the DC regenerative power supply. Please take a look.

<Overview> biATLAS is a regenerative DC power supply that combines both DC power supply and DC electronic load functions, making it ideal for evaluation and testing. It is a product developed by power electronics engineers for power electronics development. Maximum consideration has been given to control stability and noise, which are challenges in power electronics development. Additionally, we have introduced a 5kW product at an easy-to-adopt price, packaged in 40kW, 20kW, and 10kW configurations. The compatible package allows for switching between series and parallel connections, enabling a switch between 1000V and 525V, so it can be used for multiple tests/experiments with a single unit. Usage example (for the 10kW model): 1,000V 30A ⇔ 525V 60A [Currently offering a free 2-week rental] We are confident in our control stability. Please give it a try.
