UPS/Uninterruptible power supply
|
|
| In many areas we can no longer imagine today being without UPS-systems. Whereas in the past only absolutely essential equipment was protected against line disturbances by UPS-systems, nowadays each risky component which is required for smooth operation is protected by UPS-systems, helped by compact designs, modern technology and low prices. Nowadays it's impossible to imagine banks, printers, computer and logistics centres, broadcasting centres etc. without UPS-systems. We can provide you with the right system across all the performance range and for every application. |
On-line Procedure |
Off-line Procedure |
| In the classic on-line procedure (double conversion), a stabilized, distortion-free AC-voltage is permanently generated by an inverter, which is entirely independent of the quality of the line voltage supplying the system. For the user, this means that apart from supplying consumers in the event of a power failure, the system filters all line disturbances. The battery is not used in the event of line under voltage, frequency deviation and distorted input voltage. | Off-line systems supply the consumer from the mains. The system is only switched to inverter mode in case of a power breakdown or if the line voltage deviates dramatically from the nominal ratings. Line-interactive off-line UPS-systems are an economical alternative. |

View of Shutdown-Software
To ensure the perfect protection for your data, it's
necessary that the connected PCs are capable to communicate with the UPS-system.
This communication will be achieved by the shutdown software.
For this the serial interface of the PC gets
connected with the signal output of the UPS.
There are extensive shutdown-software-blocks for
the UPS-systems available.
The software interrogates the state of operation of
the UPS and guarantees an orderly, automatically shutdown of the operating
system in case of mains failure and discharged battery, so that every data file
and all processes get closed.
After ending the shutdown-process the UPS can be
switch off, so that the PC can start up without difficulties in case of mains
return.
The software is delivered on 3,5 " disks or on
a CD (other data media are possible) with a connection-wire. The installation of
the shutdown-software is easy.
It's possible to connect various operating systems
with the UPS-system. The connection could be done by a multiplexer or for
special operating systems the signal could be transferred via data line.
It's also possible to send the data of the
UPS-systems via SNMP-adapter to management stations.
The shutdown-software is available for following
operating-systems among others:
DOS. OS/2, IBM LAN SERVER MAC OS
WINDOWS 3:x, WINDOWS 95/98/2000/XP, WINDOWS NT
workstation and server
