Legrand

Daker DK Plus 2KVA

UPS

The Legrand UPS model Daker DK Plus 2000 is an uninterruptible power source with high frequency PWM technology, Double Conversion On-Line, solid neutral, Rated Power 2,000 VA – 1800 W, equipped with valve-regulated, hermetically-sealed accumulator batteries, contained in a specific compartment inside the UPS or in one or more external cabinets, sized to guarantee a minimum uptime of 10 minutes at 80% of the load.

The electronics and batteries are contained in just two rack units (2U).

The architecture of this UPS means it can be installed in either a Tower configuration or inside Rack cabinets.

The rectifier of the UPS is comprised of a control and regulating circuit (PFC), which, in addition to normal rectifier functions also:

automatically corrects the power factor of the load to restore it to a value of >0.99 with a load applied at the output at 20% of the rated load.

power the inverter without requiring energy from the batteries, even when there is very low voltage from the mains.

ensures a total harmonic distortion of the input current THDIin < 3% without the addition of filters or supplementary parts.

The bypass circuit is designed and built in compliance with the following:

Electromechanical switch

Command and control logic managed by a microprocessor that:

automatically transfers the load directly onto the primary mains line without interrupting the power supply if any conditions of overload, over temperature, continuous voltage outside of the tolerances and inverter anomaly arise.

automatically re-transfers the primary mains line load to an inverter line, without interrupting the power supply, once normal conditions of the load have been restored.

if the primary mains line and the inverter are not synchronized, the bypass must be disabled.

A diagnostic and shutdown software (UPS Communicator), if accordingly installed in a PC connected to the UPS, which allows you to access all of the operational data, make adjustments and settings to the special functions and control Windows and Linux operating system shutdown.

An optional software (UPS management software) offers hierarchic multiserver shutdown and remote management of the UPS for any operating system in a heterogeneous network (Windows, Novell, Linux and the common Unix).

Daker DK Plus 2000 is managed by a microprocessor and is able to display, on a control panel and LCD screen, the alarms and operating modes described below:

normal operation

output frequency that is not synchronized with the input

battery-powered operation

operation in bypass mode

faulty power module

overloaded

generic anomaly

incorrect neutral connection

back-up time

end of uptime

The Daker DK Plus 2000 Static Uninterruptible Power Supply bears the CE marking, pursuant to Directives 2014/35, 2104/30, and is designed and built in compliance with the following standards:

EN 62040-1 “General and safety requirements for UPSs used in areas that are accessible to the operator”

EN 62040-2 “Electromagnetic Compatibility requirements (EMC)”

EN 62040-3 “Performance and test method requirements”.
