The Legrand UPS model Daker DK 1000 is an uninterruptible power supply with high-frequency PWM technology, Online Double Conversion type, and a passing neutral. It has a nominal power of 1,000 VA – 800 W, equipped with valve-regulated sealed batteries, housed inside the UPS in a special compartment or in one or more external cabinets, designed to ensure a minimum autonomy of 8 minutes at 80% load. Electronics and batteries are housed in only two rack units. This UPS has an architecture that can be installed both in Tower configuration and within Rack cabinets. The UPS rectifier consists of a control and regulation circuit (PFC), which, in addition to the functions of a normal rectifier, provides:
- automatic power factor correction of the load to bring it to a value >0,99 already with an output load applied equal to 20% of the nominal load;
- powering the inverter without requiring energy from the batteries even in the presence of very low mains voltage;
- ensuring a total harmonic distortion of the input current THDIin.
Technical characteristics:
- Online Double Conversion type;
- High-frequency PWM technology;
- Passing neutral;
- Nominal power 3,000 VA – 800 W – power factor 0,8;
- Equipped with valve-regulated sealed batteries, housed in a special external container;
- 19” 2U Rack container.
