| Inverter Design Philosophy |
IGBT based PWM with Instantaneous Sinewave, Micro Processor control |
| Nominal Voltage |
400 / 415 V AC, 3 Phase & Neutral; stepless Adjustable (380 V AC - optional on request) |
| Regulation |
=< 1% for balanced load; =< 1.5% for 100% unbalanced load; |
| Phase Displacement |
=< 1% for balanced load; =< 2% for 100% unbalanced load; |
| Frequency |
50 Hz (0.25 Hz) in free running mode, (± 3 Hz) in synchronous mode |
| Waveform |
True Sinewave |
| Total Harmonic Distortion |
< 2% max on linear load & < 5% on non-linear load |
| Crest Factor |
3 : 1 |
| Overload Capacity |
125% for 10 Min ; 150% for 60 Sec. |
Dynamic Response Duty |
For 0 to 100% step load change the output shall remain within ± 5% & recover to ± 2% within one cycle Continuous |
