Large Power Rectifying Device

The series products are large current and large capacity rectifying device, mainly used for metal smelting, electrolysis chemical industry, and etc, can be used for heating electrolytic aluminum, electrolytic lead and zinc, electrolytic magnesium, electrolytic copper, electrolytic manganese, electrolytic salt, water electrolysis and graphite oven. It also can be used as DC power supply that similar to load.

Technical Features

◆ Industrial Personal Computer control, Spot Bus Technology, all-digital and intelligent system.
◆ Color touch screen for human-machine interfaces (HMI), information integration,easy to operate。It takes 10 minutes to learn the operation method .
◆ Working status and data of each part of rectify system is real-time displayed. Workers adjust and read the information by local area network(LAN).It’s convenient to manage.
◆ Redundant without disturbance switching technique used in Double-channel hot standby. Each channel tracks automaticly without auxiliary link to ensure the reliability of the device.
◆ Dual power supply the key devices in parallel to improve security of operation.
◆ Control system online maintenance, circuit board hot-swap to supply the production reliable guarantee.
◆ Allowance for abundant external interfaces is suitable for various communication ways
◆ Reasonable structure of rectifier cabinet, best effect of in-phase parallel inverting, attention to details, strive for excellence.
The products generally use on-load regulating rectifier transformer for voltage flat tuning, the thyristor for voltage fine-tuning. Adjustable voltage can range from zero to rated value.
