Uninterruptible DC supply (DC UPS), series UGV, according to VDE0510

General

DC- UPS series with secondary switched and modular charging rectifier units. Good efficiency with an imperceptible noise development characterize this very reliable series.
All devices of this series are designed to be full load and short-circuit proof on the side of the charging unit and protected against overload on the battery side by a fuse element.

explanation

The maintenance-free, sealed lead battery, working in standby parallel operation with the regulated rectifier, is charged up to a cell voltage of e.g. 2.27V.
The rectifier is designed to supply the connected consumers under full load and to 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. However, the autonomy time to be achieved in this case would remain the same as the connected load (see type list).
In the event of a power failure, the connected loads are supplied from the battery for the specified autonomy time without interruption.

performance characteristics

    • charging power supply with I-V characteristic, acc. to VDE 41773
    • full load/ overload/ short circuit resistance
    • mains switch/ mains control lamp (not for chassis version), mains fuse
    • V/A-meter analog- Kl. 1% for GR output (not for chassis version)
    • mains isolation transformer according to VDE 0551
    • battery protection, for 19″ rack as automatic fuse in B- characteristic in the rack front panel
