Item Type: LED tester_x000D_ Product Model: LED 2c tester_x000D_ Product Features: Portable LED light board detector (no regulation, no electric shocking, no burning beads, no glaring). Automatically adjust current and voltage._x000D_ Product Description: LED tester, LED backlight tester_x000D_ With Three Major Functions:_x000D_ 1. test the withstand voltage of capacitor_x000D_ 2. test the voltage stabilizing value of the voltage stabilizing diode_x000D_ 3. The voltage value of the light bead light board can be tested to determine the quality of the light bead._x000D_ Input Voltage: 85-265V AC (international)_x000D_ Output Voltage: 0-300V_x000D_ Product Use: Measure the voltage value of light beads, light bar, light board, voltage stabilizing diode and so on._x000D_ Advantage:_x000D_ 1. All LED backlights light up easily without power limitation._x000D_ 2. When a single light bead is not sure about the positive and negative poles and is afraid of burning the light, random testing with low current and low voltage will not burn the light._x000D_ 3. The test data is accurate, and the voltage value is the most important data to judge the quality of the LED._x000D_ 4. Safe and reliable output current of 1mA, output voltage of 0-21V. Low current and low voltage can also be used to test the voltage value of components below 21V.
