Small uninterruptible DC supply in standby parallel operation, series KUGV; according to VDE0510

General

Small DC- UPS compact series with secondary switched charging power supplies, without instrumentation. Available are versions with nominal voltages from 12VDC-30VDC. In the price-type list, however, only the common 24VDC version is listed.

explanation

The battery, which works in standby parallel operation with the regulated rectifier, is charged up to a cell voltage of 2.27V. The rectifier is designed in such a way that it can simultaneously supply the connected consumers under full load and charge the discharged battery within approx. 10 hours. For peak load times the battery can be included as a power reserve. If the connected load is not a constant load, the full rectifier power can be used as a basis for the determination of the unit power rating. The autonomy time to be achieved in this case would, however, remain the connected load related (see column connected load in the price/type list).
