Products and Technologies

A power control system

A compact charging system consolidated with solar cell panels and rechargeable batteries

●To solve a power failure
At emerging countries with a little power supply, TANAHASHI developed a convenient device for operating rooms and pharmacy rooms in hospitals. Using a commercial power supply and power peak cut algorithm, it supplies necessary electrical power when needed and instantly switches to UPS system in case of power failure.

●Advanced technology in a power control system
It is an automatic changeover and control system of power supply based on preset condition even at frequent and sudden voltage changes by use of solar cells and rechargeable batteries.
Moreover it is possible to reduce total cost by limiting generation power up to 10Kw and to control various batteries from SLA batteries to lithium batteries.

●An integrated technology
TANAHASHI calls its exclusive technology as “an integrated technology”, that starts from idea creation from the scratch and develops its system and application. It is exclusive to TANAHASHI who searches industrial products in the market and produce a new unit by assembling them.

An inspection device of solar cell batteries

To inspect if solar cell batteries operate in compliance with its speech sheet.

Power generation elements of solar cell batteries are made of crystals and could be damaged during transportation, resulting in insufficient power generation less than expected.

●Image processing technology
By lightening special beam to cell surface and process its image, TANAHASHI is capable to detect any damages or cracks (JAXA’s patented technology) and confirms its quality for the orders.
