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
