Lightning protection solutions to safeguard electronic devices and prevent data loss.

Lightning protection solutions to safeguard electronic devices and prevent data loss.

"Lightning prevention" lightning strike countermeasure solution! Have you addressed the risk of business interruption due to lightning strikes and surges? [Proven in 37 countries worldwide]

In recent years, there has been a risk of damage to manufacturing equipment, server PCs, surveillance cameras, PBX systems, and more due to intense lightning strikes. We would like to introduce comprehensive lightning protection measures to safeguard your business and data/information equipment. To protect important electronic devices and data, it is effective to use "SPD (Surge Protective Device)," "Thunder Blocker Pro," which protects devices from incoming lightning surges, and the lightning rod "dinnteco," which prevents lightning phenomena from occurring. By installing these measures together, it is possible to protect against not only the risk of direct lightning strikes but also from lightning surges generated by nearby lightning strikes.

Surge Protective Device "Molybdenum SPD"

Surge Protective Device "Molybdenum SPD"

It suppresses induced lightning surges and protects electronic devices.

In recent years, many electronic devices using low-voltage semiconductors have been widely used. These devices can be damaged by even small lightning surges, leading to equipment failures and malfunctions. High-speed response surge protective devices (SPDs) are required to minimize the energy of lightning surges. Molybdenum SPDs have achieved a high-speed response of 2.5 nanoseconds by using molybdenum in their elements. Additionally, due to molybdenum's high melting point (2,623 degrees), there is less wear on the electrodes from surge absorption sparks, resulting in a long lifespan. 【Features】 ○ High speed → Below 2.5 nanoseconds ○ Low capacitance → Below 1 pF ○ Long lifespan → Resistant to heat For more details, please contact us or download the catalog.

[Production Ended] Instant Voltage Drop Protection Device GT Series (1 kVA)

[Production Ended] Instant Voltage Drop Protection Device GT Series (1 kVA)

We protect computers, systems, equipment, and devices from momentary voltage drops and interruptions caused by lightning strikes and other issues!

"Instantaneous voltage drop" is often caused by lightning, with the majority of occurrences happening within 0.3 seconds. Even a slight drop in voltage can lead to malfunctions or shutdowns of computers and control devices on the line, power equipment such as motors stopping, losses in startup time for vacuum devices, and the production of defective products due to production line stoppages, all of which can significantly damage delicate FA systems and ultimately result in enormous economic losses. The "instantaneous voltage drop protection device" responds to instantaneous voltage drops and interruptions with power supply lasting more than 1 second. It is fanless and battery-less, eliminating the need for maintenance or replacement parts, and is maintenance-free with a long lifespan (capacitor life) of 15 years.
