TKDMR 0-330V Smart-Fit Manual Adjustment Voltage TV LED Backlight Tester Current Adjustable Constant Current Board LED Lamp Beads Test Detect Tool
LED TV backlight & constant current board (KT4H) is a high grade test and maintenance tool with three utility model patents.
This product has a powerful function: 1.Test any LED back-light strip and LED bead, 2. Test constant current board 3. Test voltages of multiple components.
This product uses AC-DC isolation Switching Mode Power Supply and a series of automatic intelligence to control the circuit, LED double table digital display ,safe and convenient.
Product characteristics
1 Manually stepless preconditioned open circuit voltage (20-330VDC). When testing, the intelligent fully adaptable to the LED light source voltage, and no need to adjust!
2. When the output voltage is preset 20V or below, using 1mA gear current to off-line test a variety of IC power supply voltage parameters ,to see if the good or bad of IC. when test the single lamp it never burn the lamp.
3. The maximum short-circuit current limit (20-150mA) can be adjusted manually, and the current is fully automatic.
4. No matter whether the high voltage or the low voltage, the lamp bar can be ultra bright safely.
5.Specially when added 1mA precision wide voltage (0-330V) constant current source output, it can develop various ingenious applications. Such as diode, voltage regulator, triode, MOS tube and other positive and reverse voltages,
and the capacitance under330V, voltage sensitive resistance, TVS transient diode and other voltages or breakdown voltages.
6. Test the constant current board, if the TV only has one group of lights, you can directly test the good or bad of the constant current board, to make sure if the problem is backlight or the constant current board.
