Hi-tech LOPOWER UPS

The LOPOWER UPS has been designed to respond to the latest demands for supplying very sophisticated low and medium-power loads using-should it be a questionof single-phase loads -thesame source of three-phase energy that is normally available.
LOPOWER is, in fact, available in tow versions: three-phase input and single-phase output; three -phase input and output. The LOPOWER project contemplates all the experience accumulated by Siel's technicians in the field of uninterruptible power supplies and uses the most advanced electronic technologies.
It also envisages special operating aspects that make it possible to use the UPS in a truly advanced manner.

Quality power

Like all of its Siel team-mates, the LOPOWER UPS constantly supplies the load with high-quality electric power, with neither electrical noise nor outages, with a strictly sinusoidal wave form, filtered and with a highly stabilised nominal value.
The systems maintain these characteristics at every moment and, inthe event of a black-out, the machine switches in zero time and continues to supply power for the established back-up time.

Low audible noise

The LOPOWER project has been particularly careful about the machine's noise level.
That's a very important characteristic for machines with such power levels which are always installed in environments where people work and live.
Innovative decisions have been implemented for the transformers and magneticcomponents, purpose-designed to generate low noise levels, for these are often the noisiest components.
As for the ventilation, very low-noise but hight-capacity fans have been incorporated and they are located in a special module at the base of LOPOWER.
The path of the cooling air is optimised so as to provide high efficiency and powerful deadening of the noise caused by the velocity of the air.

Compactness and manoeuvrability

LOPOWER is very compact compared with the powers available in the various ratings.
It contanins all the components and subassemblies of the complete UPS, including the battery for standard autonomies.
LOPOWER has castors that make handling, installation and positioning fast, easy and low-cost.

Ease of operation and control

Once installed, LOPOWER can be controlled very easily by means of its control panel, which also has a liquid-crystal display to show all the details of the operational status of the machine in real time.
The system used for the control panel is extremely advanced and uses a microprocessor which not only performs the machine control and management functions already described but also memorise a true and proper historical archive of everything that has happened with the system.
The data can be retrieved at any moment for checking and diagnostics and to permit easy and fast technical assistance.

Ease of maintenance

every Siel project starts with the demand for service. Technical work has to be as simple, undem anding and fast as possible.
LOPOWER also incorporates solutions that minimise the MTTR, that is, the mean time to repair, the minimum real time required for maintenance operations.
In the event of a breakdown, the Siel philosophy includes the replacement fof entire boards in very short time-scales and, therefore, at low costs.
Once the boards have been changed, the UPS can start up again straight away and continue to guarantee power in total safety.
And all the other sections of the machine are easily accessible for whatever maintenance in very short times.

Built-in storage battery

For standard back-up times, LOPOWER has sealed batteries located in their own compartment away from the other components.
The batteries are housed in special drawers designed to facilitate inspection and replacement when necessary.
For longer autonomies than the standard ones, as many extra battery modules as ard needed to extend the back-up time to the required duration ca be added in line with LOPWER.

Manual and static by-pass

In the event of a fault, LOPOWER automatically switches the load to the mains supply by means of the static switch without any interruption. Nevertheless, LOPOWER also has a rotary on-load mak-before-break switch. When the switch is operated, the load is supplied directly by the stand-by power source without causing any output disturbance. In these conditions, all operations on the UPS can be carried out in complete safety.
