Handbook "Basic Knowledge of Instant Low" [What is the impact of instant low?]

Handbook "Basic Knowledge of Instant Low" [What is the impact of instant low?]

A brief moment of power outage can lead to the stoppage or malfunction of factory equipment! We are currently offering a handbook that contains basic knowledge about momentary power interruptions!

"Momentary voltage dip" refers to a power outage that occurs for a very short time, instantaneously. Power companies generally refer to outages lasting less than one minute. When a momentary dip occurs, it can lead to the stopping or malfunctioning of factory equipment each time. Additionally, it can cause defects in the products being produced and take time to restart the equipment, resulting in decreased production efficiency. In the past, a momentary dip of 0.07 seconds caused enormous damages exceeding several billion yen for one company. [Handbook Contents] ■ What is a momentary dip ■ Difference between momentary dip (instantaneous voltage drop) and power outage ■ Effects of momentary dip ■ Countermeasures for momentary dip (instantaneous voltage drop) ■ Features of momentary dip protection device VSP *For more details, please refer to the PDF document or feel free to contact us.

Overload protection device "Torque limiter"

Overload protection device "Torque limiter"

Ensure reliable detection of overload and isolate input and output.

The overload protection device instantly disconnects the input and output during overload to protect the machine. It reliably detects overload, disconnects the input and output by the drive key coming off the groove, and automatically reconnects at the same torque and the same indexing position once the overload is removed. The torque setting is done with a built-in torque spring, eliminating the hassle of fine adjustments. Additionally, it serves as a flexible coupling and can be used in both axial alignment and wrapping methods. Furthermore, due to the power transmission via the drive key, it can be used in oil without any issues. 【Features】 ○ Reliable overload detection ○ Accurate operation to protect the machine from overload For more details, please contact us or download the catalog.

Ideal for lightning protection! Examples of the use of instantaneous voltage drop protection devices in the semiconductor and wafer industry.

Ideal for lightning protection! Examples of the use of instantaneous voltage drop protection devices in the semiconductor and wafer industry.

Avoid product production stoppage due to momentary voltage drops! Introducing some examples of troubles in the semiconductor, wafer, and FPD industries, along with successful cases of utilizing momentary voltage drop protection devices!

"Momentary voltage drop" refers to a brief, instantaneous decrease in voltage. Countermeasure devices have transitioned from UPS (Uninterruptible Power Supply) to VSP (Voltage Sag Protector)! The VSP (Voltage Sag Protector) is a device that provides short-term power compensation specifically for SAG (momentary voltage drops). Accidents and troubles frequently caused by momentary voltage drops due to lightning in the semiconductor, wafer, and FPD industries include: ■ Occurrence of defects in semiconductor manufacturing equipment (decreased yield) ■ Delays in semiconductor production schedules (delivery delays) ■ Increased costs due to product defects and equipment startup time losses ■ Decreased reliability among stakeholders Success stories from the introduction of momentary voltage drop protection devices: ■ Improved stability of semiconductor quality ■ Maintenance-free operation of equipment, with a lifespan of 13 to 15 years ■ Landing costs reduced to as low as one-twelfth, resulting in energy savings ■ Low introduction costs ■ Small footprint allows for effective use in clean rooms ■ No harmful substances used *For more details, please download the materials or contact us.
