- Features
1. Product Introduction
SD330 induction heating power supply control board adopts high-speed DSP core architecture design, suitable for power induction heating within 300KW, only for users with batch orders, working frequency 0.4KHz-100KHz, highly digital Seiko quality design, supports remote control and on-site The control method is an induction heating power supply product with international advanced technology independently developed and produced by the third generation of Sine Power, using IGBT as the inverter device. The control board has functions such as phase loss protection, constant current output, constant power output, overvoltage protection, constant temperature output, overcurrent protection, short circuit protection, and working status indication. Broadband self-adaption, good anti-voltage fluctuation performance, high power factor, high efficiency and energy saving, intelligent protection system and other characteristics, suitable for thermal processing, heat treatment, thermal assembly, welding, smelting and other thermal processing industries of metal materials.
The main control board 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 that the adjustment of all control loops can be completed quickly; at the same time, it has good reliability, stability, and strong anti-interference ability. Unique anti-interference measures, normal operation in harsh interference environments, control board self-diagnosis and load operation protection functions are complete, with power failure protection, overvoltage protection, overload protection, short circuit protection, etc. Therefore, whether it is external or internal, all kinds of interference and fault signals will make the performance of the control board safer and more reliable because of the above protection functions. The input and output all adopt isolation technology, which has a wide range of applications and has perfect fault detection and alarm indication. And protection function, all parameters are digital, no temperature drift changes, improve the adjustment accuracy and power utilization efficiency.
Please note: This type of control board integrates a high-voltage isolation acquisition module for DC voltage, DC current, and three-phase AC voltage signals on the basis of SD310. It is mainly suitable for occasions where the assembly space in the power cabinet is limited. Under normal circumstances, it is recommended that users choose the model SD310+SV800 can achieve the same function.
II. Performance
1. Adopt advanced control technologies such as DSP digital control system, automatic frequency tracking, and frequency feedback self-adaptation to make the equipment run more stably and efficiently. Fully automatic SMD process manufacturing, stable and reliable performance;
2. Perfect fault detection and alarm function, real-time detection of load status, load current, control signal, feedback signal loss and other parameters, designed with over-frequency/low-frequency protection functions, the protection system is more complete and reliable. Current loop (voltage loop) feedback input signal supports transformer, 0-5V and other analog input signals;
3. Working mode: constant current operation, constant power operation, constant temperature operation (optional item), process program operation (optional item), which can be selected according to different working conditions or process requirements, and supports 12/16-bit high-precision sampling control ;
4. The main control board comprehensively improves the control accuracy and adjustment speed of the system. The resolution of the current and voltage display reaches 0.1V or 0.1A, and the resolution of the power display reaches 0.01K, and the output is stable;
5. All output ports and digital input ports adopt electrical isolation design, which has better electromagnetic anti-interference protection effect;
6. Single main control board, wide frequency automatic tracking system, with fewer fault points and more precise control. The broadband design has strong load adaptability, a single power supply can meet the heating needs of various workpieces, and there is no need to frequently replace multiple main boards; it is convenient for users to quickly and accurately find the best frequency, temperature, heating depth and energy consumption through process adjustment. The process matching relationship between them.
7. High stability will not be affected by the external environment (such as temperature, humidity, etc.). Compared with the power supply of the analog control system, the power supply parameters of the digital control system are all solidified in the program, and environmental changes will not affect the internal parameters. The parameters are determined by analog devices such as resistors. These devices are obviously affected by the environment. If the temperature changes, the parameters may change. Therefore, compared with the analog control system, the digital power supply has higher stability.
8. Good anti-voltage fluctuation performance, ensuring normal operation when the grid voltage fluctuates between 350V-440V. It adopts double closed-loop control of voltage/power and current, and has the function of constant voltage and constant power operation, that is, the output voltage or power does not change with external factors, ensuring the stability of load heating.
9. The intelligent protection system can display the fault problem online and check the fault solution online. The power supply has a fault self-diagnosis function. When the operator misuses or an alarm occurs in a special working condition, the touch screen will display the fault content, click the corresponding In the help of the fault, you can query the solution to the corresponding fault. More than 90% of common faults can be quickly dealt with by operators, which greatly improves production efficiency and reduces the dependence on the technical level of operators.
