Adelsystem’s all-in-one family of uninterruptible DC power supplies offers reliable, consistent backup of the DC supply and should be incorporated where frequent power outages or dips occur. These products are particularly useful where there is a PLC or other digital communication as it negates the need to re-boot the system continuously.
The power supply section is a switched mode device for smaller, lighter and more efficient power delivery than equivalent linear devices, while the battery charger circuit is microprocessor based and uses ‘smart battery management’ techniques to ensure cells are kept in prime condition. The backup module ensures that the available power is automatically allocated between the load and the battery. Supplying power to the load is the first priority of the unit, after that the power is used to charge the batteries. In the ‘Power Boost’ mode, power is available simultaneously from both the power supply and the batteries, making maximum current available. This is used for short time periods of high current demand.
Visual and relay outputs warn of battery problems or failure, these include:
* Main or backup supply – signalled via relay.
* Battery flat - signalled via relay.
* No mains supply - LED indication.
* Battery fault – LED.
* Low battery – LED.
* Battery charge mode – LED.
* Help - blinking Code LED signals.
These devices are flexible and can be customised to meet user and application requirements. After installation, it is possible to carry out functional updates remotely from a computer.
Unpacking the technoeconomic case for cleaner power in wastewater plants Schneider Electric South Africa
