https://korean-machinery.com///inquiry

[INQ. NO. 2509M05] Established in 2017, Overplus Power Co., Ltd. has strived to develop high-temperature water solid oxide electrolysis cell (SOEC) stack for clean hydrogen production without creating any greenhouse gases on the side.
With multidisciplinary areas such as materials science, chemical engineering, electrochemical engineering, mechanical engineering, and electrical engineering, developing reliable SOEC stacks comes with big challenges. After successful short stack development, Overplus Power is now commercializing the stack.

The SOEC stack is an electrochemical device that converts water steam into hydrogen, which is expected to lower hydrogen production costs significantly in the near future. However, it is challenged with relatively low durability that needs to improve.
Overplus Power’s stack fortunately delivers excellent current efficiency and durability that can compete with global producers such as Bloom Energy or Sunfire. The company can work with system suppliers to develop entire systems with customized stack characteristics.
Compared with competitive electrolysis technologies such as PEM or alkaline electrolysis techniques, where they require 52-55 kWh/kgH2, SOEC technology only requires 37 kWh/kgH2 which results in much better business results.

https://korean-machinery.com///inquiry

[INQ. NO. 2509M04] This system consists of a multi-function digital semaphore and a gas safety master.
Its control panel consists of functions that control a flagger, a text electric sign, a siren, image equipment, a power supply, and sound. It also has a function that manages a site by displaying an instant gas-detection response by connecting with the Gas Master that comes with it. Gas Safety Master is a primary gas detection system that can be used in industrial sites that can potentially be exposed to harmful gases.
Workers can carry it freely to a site when working, and it has a linked external warning system, as well as its own alarm when an abnormality is detected. Therefore, if a field worker cannot independently perform a rescue, the external warning system alerts others to the site’s problem. In addition, Gas Safety Master has a convenient function that can create a report automatically when needed by continuously monitoring, recording and saving a site situation linking with PC using telecommunications.

Swing Blind Valve
This is a powder blocking valve, preventing the entry of ash, etc. It is an innovative product that can reduce the water-backwashing period when backwashing an electric precipitator with water to reduce fine dust by installing at a bottom ash and fly ash facility in a thermal power plant. It has the advantage whereby a water-backwashing period is very greatly reduced because a valve is turned on-and-off by turning a disc from side to side when using a blind valve. It also has outstanding air-tightness performance due to a moving seat ring moving up-and-down and a triple O-ring.

Power Supply Units for Electric Vehicle Chargers

March 24, 2025 by Leave a Comment
https://korean-machinery.com///inquiry

[INQ. NO. 2503M01] AHA Co., Ltd. recently announced that its 30kW power supply unit (PSU) for electric vehicle (EV) chargers, the first of its kind in Korea, has received UL certification. Through this, the company has secured a bridgehead for entering the U.S. market.
While Korean companies’ EV-charging infrastructure product lines are gaining prominence in the global EVC markets, PSUs, the core equipment of electric vehicle chargers, are still heavily dependent on Chinese products.
Since PSUs are expensive components, the Korean PSUs obtaining UL certification is all the more significant amid the recent U.S.-China trade dispute.
AHA’s 30kW PSU combines multiple low-power PSUs to provide a wide output voltage range of 300V to 1000V DC, and a maximum current of 100A. By applying power factor correction (PFC) technology, the product has achieved high efficiency of up to 96% and low standby power, and its patented PSU address auto-setting technology enables rapid diagnosis and replacement in the event of a failure.
AHA’s 30kW PSU was finally selected as a verification test product for the Ministry of Environment’s research project to strengthen the competitiveness of electric vehicle rapid charger PSUs conducted last year. It passed the Energy Star efficiency, reliability, and safety tests set by the Ministry of Environment, verifying its excellent performance.
Based on this success, AHA applied for slow chargers and fast chargers at the same time for the business operator selection contest of the 2025 charging facility subsidy payment project, and is currently waiting for the results.
AHA has invested more than KRW 1 billion in slow & fast chargers and PSU automatic inspection and durability test equipment, and is aiming to develop a 40kW PSU and a 480kW power bank by the end of 2025. After moving the R&D center to Magok-dong, Seoul, the company is converting the Gimpo headquarters in Gyeonggi-do into an electric vehicle charger production line, and is thus building the largest production base in Korea. AHA is currently negotiating with multiple companies for consignment production.
AHA has been exhibited EV chargers and PSUs at major international exhibitions such as CES 2024, GITEX 2024, and ISE 2025. It has received favorable reviews from overseas EV and PSU manufacturers, etc. AHA expects that overseas exports will begin in earnest with this UL certification.
