Text for tenders: UPS PMC 40 20 kW module


UPS PMC 40 20 kW module

Compact, modular and enclosure-independent three-phase

UPS module. Rated output: 1x 20 kW. Uses

double-conversion technology and has VFI-SS-111

classification. Direct mounting in the 482.6 mm (19

inch) level, combined population with other hardware

in the same rack is possible.



For simplified handling the UPS modules must be

designed as slide-in modules to be installed in any

482.6 mm (19 inch) enclosure by means of a special

frame.



To achieve the highest possible level of supply

availability for connected equipment, only systems

working according to the continuous converter

principle (online operation) to classification

VFI-SS-111 (voltage and frequency independent) to EN

62040-3 are allowed. Transformerless UPS systems are

approved only.



In the event of a mains failure power is supplied for

the converter without interruption within the given

stored energy time from the batteries, or during the

time until the public mains returns or an auxiliary

mains takes over the power supply of the rectifier.

The batteries are recharged automatically via the DC

converter.



Every UPS module has a user-friendly, menu-assisted,

at least 2-line (40 characters) LCD display at the

front for operating the system.  Control of the system

and access to the event register and to the service

mode may be made via this. LEDs for the current flow

and operating mode display and respective push-buttons

for control and menu navigation must also be provided

in the display.



The UPS system must feature an automatic battery test

that is initialised at regular, user definable

intervals. The system demands a stationary,

maintenance-free, sealed gas recombining battery with

an expected service life of 10 years.
