[Technical PR] Custom DC Power Supply

[Technical PR] Custom DC Power Supply

We will provide a power supply for each item!

About 10 years ago, when we were developing a small hydrogen generator at the university, we frequently encountered malfunctions of commercial DC power supplies due to overcurrent at the time of power-on. Therefore, we conducted experiments and development in collaboration with TDK-Lambda, resulting in the dedicated power supply shown in the photo, which was developed specifically for cell 1). With the development of this power supply, the malfunctions during power-on were eliminated, and we were able to produce a stable small hydrogen generator as a product, with almost no failures (only 2 out of 50 units failed due to being used in dry operation). Due to this background, we kindly ask that you refrain from purchasing the power supply alone.

[Switching Power Supply Solutions and Proposal Examples] Innovations in Circuit Configuration

[Switching Power Supply Solutions and Proposal Examples] Innovations in Circuit Configuration

Innovative circuit configuration! Introducing a case that achieved an input voltage range of three-phase 440 to 480V.

We would like to introduce a case study of solutions and proposals for "switching power supplies." The issue we are presenting this time is the concern that "adding a transformer to accommodate high voltage increases product size and cost." Currently, there are few components that can handle the voltage, and a step-down transformer is being used to reduce the voltage. To address this, we devised a circuit configuration and used available components to achieve a switching power supply that supports an input voltage range of three-phase 400V. 【Case Overview】 ■ Challenge - Adding a transformer to accommodate high voltage increases product size and cost. ■ Result - Achieved a switching power supply that supports an input voltage range of three-phase 400V. ■ Product - Switching power supply. *For more details, please refer to the related links or feel free to contact us.
