We will exhibit at the 9th Railway Technology Exhibition 2025.

Leave the development, design, and manufacturing of custom industrial power supplies to us.

Our company designs and develops custom power supplies for the railway industry. Custom power supplies are specially made power sources tailored to the customer's equipment and specifications, capable of meeting various demands that commercial power supplies cannot, such as harsh environments, packaging, precision, lifespan, external signals, external noise, and small lot production. In particular, power supplies used in the railway industry often require compliance with vibration standards and long lifespans, leading to the adoption of custom power supplies across a wide range of applications. [Reasons for Choosing Us] ■ Development of custom power supplies compliant with JISE4031 (vibration standards for railway vehicles) ■ Development of custom power supplies in accordance with IEC 62236 (railway EMC) ■ Development of custom power supplies that combine long lifespan and high durability *For more details, please refer to the related links or feel free to contact us.

Introducing our achievements in customizing DC/DC converters built into railway safety devices!

We would like to introduce a case study of the design and development of a "DC/DC converter" built into a railway safety device that our company designed and developed. Initially, we planned to use standard products upon receiving the design request for the safety device. However, the customer expressed a desire to "also pass the device's signals through the cable supplying voltage to the device," which led them to consult us for a custom product. We designed and developed a converter that meets the customer's requirements, and they were very satisfied with the result. [Requirements] - The customer wanted to pass the device's signals through the cable supplying voltage to the device. - They wanted to supply input voltage to a separate circuit. - They needed a converter of an appropriate size that matches the device. - They wanted the specification to allow for power supply from a battery to continue operation even in case of abnormalities (such as power outages). *For more details, please refer to the PDF document or feel free to contact us.

No manual switching of the input power supply voltage! Continuous input is achieved through innovations in the control circuit.

This is a case study of a DC/DC converter (module for VME 3U size) that supports ultra-wide input. At the customer's request, they wanted to cover multiple models with DC24V/48V/72V/110V, but due to cost issues and the complexity of purchase management, they consulted about wanting to consolidate into one model. Additionally, for overseas products, it was necessary to switch control circuits for each input voltage range. By innovating the control circuit, we achieved continuous input of DC24V/48V/72V/110V without the need for manual switching of the input power supply voltage. 【Case Overview】 ■ Application: Railway safety equipment ■ Input voltage range: DC24V/48V/72V/110V (DC16.8V to 138V) ■ Output specifications: 3.3V/10A ■ Number of channels: 1 channel ■ Efficiency: 65% or more ■ Size: 40W × 129H × 233D ■ Applicable standards: JIS E 5006, JIS E 4031, IEC62236-3-2, IEC61000-4-2, IEC61000-4-11, JIS C 60068-1, VME compliant, etc. *For more details, please refer to the related link page or feel free to contact us.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

SPACECOOL Co., Ltd. is pleased to announce that it will exhibit at the "Japan Pavilion" established by the Ministry of the Environment at the 30th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP30), which will be held in Belém, Brazil, from November 10, 2025. "SPACECOOL" is a radiative cooling material that enables zero-energy cooling by dissipating heat into space. At our exhibition booth, we will showcase examples of its use not only in reducing air conditioning energy in buildings but also in heat mitigation measures (adaptation strategies) for tents and parasols. The Japan Pavilion aims to promote excellent technologies, products, and services that support global decarbonization and adaptation to climate change, and to achieve Japan's long-term climate change goal of "net zero by 2050." We believe that our participation plays an important role in this endeavor. Through this exhibition, we aim to accelerate our initiatives with local partners in regions severely affected by heat issues, such as the Middle East, including Saudi Arabia and the United Arab Emirates, as well as Southeast Asia, contributing to global decarbonization and climate change measures.
