Because UPS batteries are so imperative to business continuity
Replacing Batteries
The safe operation of the battery is of vital importance for your systems. Therefore, we already are setting very high standards to our choice of battery suppliers. Basically batteries have got a limited lifetime, however. Depending on the application and ambient conditions, the battery life time
may vary considerably. We recommend our customers to check the status of their battery regularly by our staff. Our service technicians are constantly trained in collaboration with our battery suppliers. Of course, the batteries are disposed of after successful replacement accordingly by our technicians.
Battery Symmetry Supervision
To ensure the proper operation of the equipment, a monitoring of its battery systems is essential. The Battery Symmetry Monitoring System („BASYM“) is a simple and economical solution for this monitoring. The standard software of the UPS automatically or manually initiates a battery test. However, this test battery has only a limited informative value about the battery status. The optionally available Battery Symmetry Monitoring Systems (BASYM) offers more differentiated and comprehensive diagnoses. In addition to the total voltage the center of the battery circuit is monitored. If a defective battery cell is detected the center will be shifted and an alarm will be triggered.
Battery Analysis & Care System
In addition to a monitoring of the battery symmetry there is also the possibility to monitor every single battery pack by BACS module. These BACS modules are connected to each battery and monitor the individual block voltages and block temperatures. The BACS modules ensure a uniform block voltage in the battery circuit and extend the life expectancy of the battery.
Earth Fault Supervision
Many DC power sources are constructed isolated, that is, the DC voltage is electrically isolated from the input power. As a consequence the protection of the consumer must be basically two poled and that the DC bus has to be checked with a ground fault supervision permanently. If a defective consumer generates a ground fault, no backup is triggered thereby initially. The protective action of the isolated system, howe- ver, is repealed. To detect this error, an earth fault monitoring is mandatory or required. For this purpose MGEC offers with its Earth Fault Supervision System „ESW“ a cost-effective solution.
