1 The control board adopts advanced integrated circuit as the core of the control system. The control ability is extremely strong and the integration is high. The whole control circuit is installed on a printed circuit board of about 280*220mm. The connection with the main circuit is only forty or fifty. It's simple and reliable, but it has powerful controls.

2 The control board adopts three-phase power supply synchronous direct input, which eliminates the large-scale synchronous transformer, etc., which further simplifies the whole circuit, reduces the equipment volume, is easy to install and debug, and is easy to maintain. If the control system is faulty, as long as the standby board is used It can be replaced, saves time and effort, and does not affect production.

3 The control board uses a built-in solid-state relay instead of the intermediate relay of the peripheral to control the start and stop, which not only saves cost and equipment volume, but also makes the connection easier.

4 The control board has perfect multi-channel protection system such as over-current, over-voltage, current limiting and voltage limiting. Once the circuit fails, the protection system can operate in a short time, and reliably protect valuable components such as thyristors and intermediate frequency capacitors. Damage, causing unnecessary losses. The control board also has a protection action, when the power adjustment potentiometer rotates counterclockwise to the end, the protection system automatically resets, effectively preventing the misoperation and the power system is quickly started in a high power state, and has a large impact and causes components. damage.

5 The control system adopts the functions of zero voltage soft start and slow start, and adopts advanced double closed loop adjustment system, which can be started 100% reliably in actual use and has no impact. In actual operation, the equipment can work stably and reliably even when the load changes greatly.

6 The control system has fewer adjustment points. After the control board is installed, the user only needs to adjust the overcurrent, overvoltage, current limiting, and voltage limiting.
