Kit parameters:
Power supply power supply: DC12V 2A
Floating can be called lighter objects (less than 50g)
Main control board: The suspension system is controlled by a single -chip microcomputer to save complex peripheral circuits. The welding is simple. Only a small amount of components are used to control more stable and reliable.
Note: Working for a long time, the 1293 chip will have fever.
Finished product size: 90*90*25mm
Weight: about 180g
Features:
This product mainly includes single-chip microcomputers, strong magnets, coils, Hall sensors, signal amplifier circuits, H bridge drive circuits, and DC-DC antihypertensive circuits. The closed-loop control method is used to make the static characteristics of the static static characteristics of the setting.
The single -chip microcomputer continues to detect the position of the suspended body by sampled the two Hall sensors, and the magnetic field force of the coil is controlled by driving the H bridge circuit to control the coil, so that the suspended body will not deviate from the center position, and it can achieve a long -term stable suspension function.

Instructor:
1. Put the flying saucer base (the base of the suspension system) on the horizontal desktop. (If the desktop is not well displayed, it will not be suspended).
2. Connect the power of the magnetic suspension base (DC12V 2A). After the normal connection is connected, the power indicator is not on.
3. Keep the hand in the hand, hold the suspended support, and at the upper side of the base of the base, about 10cm, so that the display of the display of the display is slowly close to the center of the system. This position is the suspension position of the displayed trim (about 12mm -15mm above the base). After grasping the sense of balance of the shot, let go of your hands slowly, and the display support can be suspended and rotated in the air.
4. Please ensure that the system is far from lyric products (at least 20m), such as computers, audio, and other products with medium waves and magnetic forces. Otherwise, the display will not be able to suspend the power supply normally, such as the interruption, and the display will not be suspended normally. If it is not used for a long time, the suspension support is separated from the base.
5. If you install your own magnet, you must pay attention to distinguish the magnet NS direction. When the suspended support and the base magnet are sucked, the indicator light is on when the suspension tray is placed. Explain that the magnet is installed correctly, otherwise it is reversed.
Points to Note:
1. Avoid the display on the hard ground or collide with other objects, otherwise it will damage the suspension system.
2. Please make sure that the suspended support is placed in the correct position of the suspension system.
3. Avoid violent vibration or tapping the base, otherwise the suspension system installation in the base will be easily damaged.
4. This product is magnetic. Please keep the distance from the watch and the mobile hard disk easily maintain the distance of more than 20cm.
5. Do not repeat the suspension support over the base in a short period of time, otherwise the difficulty of the shadow shadow and the suspension support will cause the heat of the suspension system to rise rapidly.
6. If it is difficult to display the trustees during use, please break the base and restart the machine after 5 minutes.
