"Tough charger" that endures even in harsh environments.

The HEP Series is a battery charger that supports a wide input voltage range with a three-stage charging method. Despite being a "high-quality" charger with various features and characteristics, the HEP Series is designed with an aluminum case filled with thermally conductive silicone, making it "tough." It can withstand applications in environments where high temperatures, high humidity, dust, high vibration (10G), oil (including machine oil), steam, altitude, oil smoke, and corrosive gases are present, which is why it is widely adopted due to its toughness. It is equipped with a PFC power factor correction circuit. The output voltage and current can be adjusted via an internal potentiometer. 【Features】 ■ High efficiency of 93.5% to 95.5% ■ Equipped with PFC (Power Factor Correction) circuit ■ Output voltage and current adjustable via internal potentiometer ■ Aluminum housing with high heat dissipation effect ■ Suitable for lead-acid and lithium-ion batteries ■ Adopts stage charging *For more details, please refer to the PDF document or feel free to contact us.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm. Please feel free to contact us for more information!

● The production time for casting prototypes can be shortened! Since model production is not required, the time needed to create prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! With one molding process, different products with similar shapes or varying dimensions can be molded at the same time. This allows for the verification of multiple types in a short period.

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 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 you require a detailed technical explanation, please contact us.
