 Highly reliable fully digital UPS control
|
Reliability and robustness are key requirements for the power supply systems running the crucial systems in our society. Air traffic control systems, traffic monitoring systems, banking, city gas monitoring, and stock exchanges cannot function on power supplies that fail.
The latest UPS systems run in parallel, "Hot swappinghallows individual UPS components to be removed or added while the whole system is in operation, increasing the reliability of the system as a whole.

[Features]
1. Great improvements in system reliability via parallel operation
Because the system involves UPS systems operating in parallel, a faulty UPS system can be removed without adverse effect on the power output of the system as a whole.
2. Simplified Inverter Unit
By reducing the number of IGBT units and parts, the units are kept simple, reducing manufacturing steps and cost.
3. Reduction of wires between devices
The complex wiring needed in conventional parallel UPS systems has been eliminated. |
|
Once a great source of problems, we have added redundancy to the control power supply, making the system more resistant to unexpected problems in the control power supply. |
|
A parallel monitoring board independent of the UPS with an output voltage monitor has been installed which immediately switches to the bypass power supply when an anomaly is detected. |
|
We have added redundancy to the control power supply on the parallel monitoring board and have improved its reliability. |
