IGBT Inverter Control 0.1~100kHz Frequency Within 300kw Power Induction Heater Control Board

SD310 series resonance induction heating power supply IGBT control card is using DSP + CPLD structure design, highly digital exquisite industrial quality design. Supporting a variety of network remote control and on-site control methods, it is an inductive heating power supply product with international advanced technology level developed independently for the third generation by SinePower. It is using IGBT as the inverter device. The control board has functions such as phase loss protection, power on soft start, soft stop, constant current output, constant voltage output, overvoltage protection, overcurrent protection, short circuit protection, and working status indication. Broadband adaptive (from 1 to 50KHZ), it is with good voltage fluctuation resistance, high power factor, high efficiency and energy saving, intelligent protection system and other features, suitable for various of metal heat treatment, welded pipe, steel production line and other hot processing industries.

The main control card continues to lead the innovation of the core control algorithm and software technology in the industry. The structure and operation processing speed of the control software package can ensure the adjustment of all control loops finish quickly. Meanwhile, it has good reliability and strong anti-interference ability, with unique anti-interference measures, it can be operated normally in harsh interference environment. Complete protection functions such as self-diagnosis, load operation protection, power failure protection, overvoltage protection, overload protection, short circuit protection, etc. Therefore, no matter external or internal interference types and fault signals, the performance of the control card will be safer and more reliable due to the above mentioned protection functions. The input and output are all isolated, and the scope of application is wide. It has perfect fault detection, alarm indication, and protection function. All parameters are digital, no temperature drift changes, which will improve the adjustment accuracy and power utilization efficiency.
