"Magusign" is an energy-saving magnetic reversal display that uses instantaneous pulse currents to flip a permanent magnet disk (display panel) for displaying information. It consumes no power except during the reversal operation, and the disk maintains its position due to residual magnetism. The disk operates solely through magnetic reversal, ensuring extremely high reliability and can be used semi-permanently. The color surface of the disk uses fluorescent colors, making it vivid and easy to read, allowing for information categorization by color. [Features] - Energy-efficient and self-holding - Long lifespan - Excellent visibility For more details, please contact us or download the catalog.

The power save monitor can easily be configured in systems for maximum power suppression primarily for high-voltage users with a demand of less than 500 kW. Pulse detection values are transmitted from the wireless transmitter on the pulse detection side to the display of the wireless power monitor via low-power wireless communication. Since pulse values are transmitted wirelessly, wiring is unnecessary, making installation easy. If the radio environment is not good, a wireless repeater can be deployed in between to improve wireless propagation. 【Features】 ○ Easily suppress maximum demand power for high-voltage users primarily under 500 kW ○ Alerts with warning displays and buzzers when the set target value is predicted to be exceeded in the office ○ Compact and lightweight, can be installed in available space in the cubicle ○ Transmits to remote offices from the cubicle using low-power wireless communication without wiring ○ Measurement results can be analyzed using spreadsheet software via USB cable For more details, please contact us or download the catalog.
