8. Benefits to customers

Items	Chunshu Rectifier	Chunshu rectifier's benefits to user
Reliability	High, running 24 hours a day, for sapphire crystal growth could last for more than 20 days non-stop working	Non-stop working during plating process, less trouble, no loss
Cabinet	Powder coating, IP45, prevent corrosion from gas or moisture in plating factory	Protect inside components and control board, upgrade reliability
Efficiency	High, above 87% for 9V output rectifier	Save running cost (electricity cost), energy saving
Lifespan	Long, more than 15 years without fault	Average cost for one year is very low
Protections	Complete, Phase loss, input under voltage, overvoltage, output under-voltage, overcurrent, overheat, short circuit	Safe, protect the rectifier and plating line, high reliability, long lifespan.
Touch screen	Included, DC current, voltage display, operate Start/Stop, local/remote control selection, CC/CV selection, history data, output waveform display. When fault occurs, it will alarm, and tell fault type to help troubleshooting	Easy to see and operate, repair effectively and easily
Remote control	Included, start/stop, voltage, current display, output adjustment etc.	Easy to operate in remote place
Cooling	Water cooling in hot temperature (45 Celsius degree), we use water cooling plate, and water cooled transformer(approved patent). Forced air cooling also available	Stable running of rectifier, because when rectifier gets hot
Components and materials	Good quality, main components are imported products, example: we use digital meter 200RMB above	High quality of rectifier
Control	DSP digital control, USA company DSP chip, control board developed by ourselves, program approved software copyright	High accuracy, high stability, fast response time
