Specification:Supply Voltage: 12V2A DCPower Consumption: 2-10WSize(L*W*H): 9*9*22.5cmFeatures: high stability, high sensitivity and heavy loadComposition: composed of analog circuit + Holzer sensorSuspension Weight: The maximum weight of suspension is about 50 grams How to place suspended solids:1. First connect the power supply.2. Hold the magnet slowly close to the coil from bottom to top. When the distance is about 2 cm, you can feel the suction provided by the coil and let go after stabilization.3. If the magnetic force is insufficient, the blue potentiometer on the board can be adjusted to increase the magnetic force clockwise, reduce the magnetic force counterclockwise, and adjust the magnetic force to the best position, otherwise it will shake. Note:* Do not let magnets adsorb on the coil when energizing, otherwise it will easily damage the device.* If the floater is unsuccessful for a long time, the temperature of the triode and the coil will rise. It is suggested that the floater should be pulled out after 5 unsuccessful times and try again after cooling.* The magnet is far away from other electronic products, such as mobile phones, bank cards and so on.* Long time loading requires additional fans. Otherwise, the temperature of the coil will affect the normal operation of the sensor. Package Included:1 x Finished Magnetic Suspension
