Features: 1.When the DC voltage of the power supply exceeds 16V, the ballast will automatically stop working and the output power will not exceed 35W to protect the ballast and avoid bulb damage. 2.When the DC voltage of the power supply is 9V, the ballast can work; when it is lower than 7V, the ballast stops automatically to avoid damage. 3.When the ballast is not connected to the light bulb and is in a no-load state, the ballast will automatically stop working to prevent high voltage electricity from hurting the staff. 4.When the ballast encounters an unexpected situation and is in a short circuit state, the ballast stops automatically to avoid damage. 5.When the stabilizer is being installed, and the operator makes a mistake and the positive and negative poles of the input power are reversed, the stabilizer automatically stops working. 6.When the input current of the power supply is a standard voltage of 12.8V, the current is not less than the actual measurement of about 5.5A, so that the luminous flux of the connected bulb reaches 20% of the standard brightness within 1 second of the startup; within 3 seconds, the luminous flux reaches 80% of the standard brightness.
