In view of the fact that many buyers are bought and modified, and are unaware of the machine parameters that need to be modified, the fact that power on can successfully. There are a number of areas that can cause misalignment, voltage, power, connections, structures, etc. that can cause misalignment.
The working voltage of the light bar must be any voltage between 60V and 165. It cannot be less than 60V. It cannot be greater than 165V, the design working limit voltage condition of this product must not be higher than 165 V. If the voltage is exceeded, the display may go dark or the lamp may flicker.
This product only has constant current, no constant voltage, and the voltage will automatically adjust to the corresponding voltage according to the required voltage of the light bar, so it is not necessary to mess with the measured voltage without load.
The quality of the products that are marketed in this condition is stable and reliable, and may cause ailments due to: First, the short circuit caused by incorrect operation; Second, it does not provide the correct voltage or signal to each function pin, the polarity of the light bar is not connected correctly;
The actual parameters are completely beyond the product parameters; (for example, the voltage of the light bar needs more than 180V will not be able to drive...)
