  1. The new 3-ph and 1-ph UPS familyFrom 10 kVA to 30 kVA Alcor & Mizar

  2. Alcor – Mizar: power ratings Mizar 10kVA, 15kVA “Mizar and Alcor are the most famous double stars in the sky. At good conditions the double can be seen without problems. However it is not sure if Mizar and Alcor really orbit each others or they are only neighbours.” Alcor 20 kVA, 25kVA, 30kVA

  3. Alcor – Mizar: general diagram (1) By-pass Input Inverter LOAD Static Switch Output Inverter Batteries

  4. Alcor – Mizar: general diagram (1) NEW No DC voltage booster No battery charger Sinus-shape current (cosj=1, THD < 5%) Power Factor Control (PFC)

  5. Alcor – Mizar: configurations (1) • Alcor – Mizar have big configuration capability. Each unit can be configured by LCD (password protected): 3 phase IN – 3 phase OUT 3 phase IN – 1 phase OUT 1 phase IN – 1 phase OUT Also: 1 phase IN – 3 phase OUT if required

  6. Alcor – Mizar: configurations (2) Mizar and Alcor are available in the following configurations: • Stand alone • Hot stand-by (eco-mode) • Redundant Parallel or full power parallel * It is possible to have maximum n°8 units in parallel. ** The communication between the units of the parallel system is ring type by optical fibres.

  7. Alcor (20/30 kVA): power components (1) 120ARMS three phase inverter AC terminals DC terminals IGBT terminals

  8. Alcor (20/30 kVA): power components (2) Static switch (SCR 85 ARMS) • Load on Inverter • Load on Bypass • Precharge from AC mains AC Terminals AC

  9. Mizar (10/15 kVA): power components (1) 60ARMS IGBT In 1 UPS: 6 x (3 on input, 3 on output)

  10. Mizar (5/15 kVA): power components (2) 25 A relay • Load on Inverter • Load on Bypass • Precharge from AC mains

  11. Alcor – Mizar: LCD display Standard Powertronix (as in SNova) Start/Stop Load switching Rated values configuration Check alarms / status 8 languages available

  12. Alcor – Mizar: design details The same mechanical design for different UPS sizes All power components on 1 board Same control logic for all UPS EASY to MAINTAIN

  13. Alcor – Mizar: operating principle (1) load L DC ~ = ~ = IGBT IGBT Pulse width modulation Measure & regulation

  14. Alcor – Mizar: operating principle (2) Input inverter control details DC voltage regulation (2 x 405 V) Battery charge and control Input current limitation • (it operates as rectifier + DC voltage booster + battery charger)

  15. ~ AC = Alcor – Mizar: operating principle (3) PFC: Power Factor Control DC voltage regulated at reference value DC The current has “the same shape” of AC voltage i UPS R v

  16. Alcor – Mizar: operating principle (4) PFC: Power Factor Control High sampling speed (64 µsec) Switching frequency up to 16kHz High speed A/D conversion (32 measurements: voltage, current and temperature) Low harmonic distortion without transformers or magnetic components (12-pulse)

  17. Alcor – Mizar: operating principle (5) OFF +VDC/2 Firing input inverter IGBT the DC voltage value can be regulated -VDC/2 Vmains N ON Current path (T/2)

  18. Alcor – Mizar: input side measurements voltage current

  19. Alcor – Mizar: operating principle (6) Output inverter regulation Output voltage regulation (sinus wave voltage 192 points/period) Current limit (short circuit protection) Output current limitation (overload)

  20. Alcor – Mizar: output side measurement voltage current

  21. Mizar: some rated data  input

  22. Mizar: some rated data  output

  23. Alcor: some rated data  input

  24. Alcor: some rated data  output

  25. Alcor – Mizar: batteries • The unit is equipped with 60 INTERNAL batteries (2 x 360 V) • An additional cabinet with120 batteries is availablefor extended autonomy
