SPD stands for Surge Protective Device, which is a surge protection device that protects electrical equipment from transient overvoltages (induced lightning surges) caused by phenomena such as lightning, which can travel through power lines and communication lines. Mitsubishi Material's "Lightol" can be installed in control panels and distribution boards to protect multiple electronic devices with a single unit. It is compact in size and can be easily retrofitted to existing equipment. For more details, please watch the video. Lightning occurs not only during summer thunderstorms but also frequently during winter low-pressure systems when the air is dry. Due to global warming, the atmosphere is becoming more unstable, making permanent surge protection measures essential. Abnormal voltages (induced lightning surges) caused by lightning can damage manufacturing equipment in factories, office OA equipment, medical devices, and more. The recovery time and costs associated with the failure of such electronic devices can be significant. Lightol responds quickly, is resilient to repeated surges, and has a long lifespan, protecting critical equipment, electronic devices, and precision machinery from the damage caused by induced lightning surges. *For more details, please download the catalog or contact us.

Lightning occurs not only during summer thunderstorms but also frequently during recent guerrilla rainstorms and winter bomb cyclones when the air is dry, making year-round lightning damage prevention measures essential. Induced lightning surges (abnormal voltages) occur on power lines when thunderclouds approach, leading to failures in manufacturing equipment, precision instruments, office OA equipment, and household electrical appliances. The recovery from these failures can be time-consuming and costly. The "Lighter (LTP Series)" protects important electronic devices and precision machinery that cannot afford to fail from induced lightning surges! By installing just one unit in the control panel or distribution board, it serves as a surge protector (SPD)/lightning arrester that can protect numerous electronic devices. Its compact size allows for easy retrofitting to existing equipment. Additionally, it responds quickly to induced lightning surges, with a maximum discharge current of 20kA, and is durable and long-lasting against repeated surges. We encourage you to consider it for preventing failures and troubles caused by induced lightning surges in NC machine tools, robotic machinery, FA equipment in manufacturing lines, industrial equipment, and production facilities for food, pharmaceuticals, cosmetics, as well as OA equipment like computers and servers, precision medical devices, and electronic products. *For more details, please download the catalog/explanation document.

• POS system

A surge absorber is an electronic component designed to protect electronic devices from abnormal voltage (surges) that occurs instantaneously. By connecting a surge absorber at the entrance of a circuit, it allows only the abnormal high voltage to be grounded instantly, thereby protecting the components on the circuit side from surges that invade through power lines or communication lines. Surge absorbers are also referred to as surge protective components, gas arresters, surge arresters, and gas discharge tubes (GDT). ~ Thunderstorm Season: Are You Struggling with Surge Countermeasures? ~ A surge refers to an abnormal voltage that occurs instantaneously. Surges can be classified in various ways depending on their causes, but Mitsubishi Materials provides countermeasure components (surge absorbers, surge protectors: SPD) and solutions specifically for induced lightning surges and electrostatic discharges, which are particularly problematic in circuit design. We offer proposals from various surge tests of your products to surge countermeasures. We provide materials that clearly explain the mechanism of induced lightning surge generation and the protection of electrical/electronic devices. For more details, please check the "Application Note for Surge Absorbers."
