UPS: MKD 700
– 3000 VA RT (XL)
UPS Device Description

The device series, format and housing sizes
The MKD 700
– 3000 VA series is manufactured in various performance
versions and with an XL variant for each version. All versions are housed in a
combined housing format (RACK / TOWER). A housing size (2 HE) employs the
corresponding power values.
Fig. 3-7 Die MKD RT series can be used as a conventional RACK mounting
unit (top) or as a TOWER standing unit (bottom).
All devices can fundamentally be operated with an external battery bank
whereby the entire capacity through the addition comes from the internal and
external battery banks. However, connecting an external battery bank to a
standard device is not recommended due to the low charging current.
Therefore, the XL versions of the devices have been specially equipped with a
more efficient charging unit to also charge external battery banks (high capacity)
within a reasonable charging period and, consequently, achieve an acceptable
duration for continuity of service.
