Application
This is rectifier used for 5000A 12V Switch Mode Power Supply Water Cooling for Plating Electrolysis Anodizing Water treatment.
1). Power saving about 17% due to high efficiency of our IGBT rectifier, attached Excel form for your reference.
| Item | Oil cooled SCR Rectifier | Water/air cooling IGBT rectifier |
| Rated output power | 1000A*12V=12kW | |
| Annual working hours | 6300hours/year(consider 21 hours/day, 300 days/year) | |
| Assuming efficiency at rated output | 75% | 90% |
| Power consumption/year | 12/0.75*6300=100,800kwh | 12/0.9*6300=84,000kwh |
| Saved power in one year | 100,800-84,000=16,800kwh | |
| Saved electricity bill (5 Rupee/hour) | 16,800*5=84,000 Rupees | |
| Saved power percentage | 16,800/100,800= about 17% | |
4). Customer feedback Plating quality by IGBT rectifier is better than SCR rectifier.
5). Compact size, IGBT rectifier only about 1/6 volume from SCR rectifier if for same DC output power:
Cooling method: Water cooling
