3 PHASE LIFT INVERTER 5KVA TO 35KVA

 

Features

  1. LCD will display –

> battery voltage

> inverter output voltage in each phase

> load in VA in each phase

> mains voltage in each phase

> phase sequence error (instead of RYB if you connect BYR)

> phase imbalance (voltage difference between phase more than +/- 20%)

> Single phase prevention

> charger on/off

> solar charging /mains charging

> inverter standby on/off

> overload : if load is above 100%

> overload trip

> short circuit trip

  1. Menu driven set-up. There is no preset, the parameters such as battery low, charging current, inverter output voltage, load etc can be set by scrolling up and down keys and press enter.
  2. Priority solar charging
  3. No load shut down and auto restart on load
  4. Inbuilt SMPS type constant current charging with full charge cut-off.
  5. 20 KHz operating frequency while charging, absolutely no sound.
  6. Pure sine wave output
  7. DSP based very low component cost design

Highlights

  1. Full bridge configuration based on IGBT half bridge module
  2. Only three IGBT half bridge modules are sufficient for three phase
  3. Transformer-less ferrite based design is also possible
  4. DSP based intelligent control
  5. LCD based display for user-friendly display of parameters and status
  6. Protection against phase imbalance and phase sequence error
  7. Inbuilt single phase prevention
  8. Protection against overload and short circuit
  9. Buzzer indication for battery low, overload, single phase, phase imbalance, phase sequence error conditions. System continues normally if the error is corrected.
  10. Cutoff and auto restart with permanent cut after 5 consecutive cut offs.
  11. SMPS type constant current charger with full charge cutoff.
  12. 20KHz switching frequency resulting in silent operation. No audible noise.
  13. Pure sine wave output
  14. Protection against accidental output feedback disconnection.
  15. Indigenous design with proven technology
