1) Description:
This DC-AC converter for single lamp LCD backlight. Having a constant current control function, the energy of the current 7-inch to 15-inch tube provide a stable 6.0mA. It has an open circuit, short-circuit protection function automatically.
2) Note:
* The lights line current use high-frequency current meter measurement measurement.
* The Screen inverter has a 1.5A fuse.
* Backlight automatic short circuit protection function.
* The switching (ON / OFF) control input terminal of the backlight.
3) printed circuit board:
Size: 80 * 14 * 6mm
4) electrical performance characteristics:
Input voltage: Vin = 10.0-13.5V
Input Current: Iin = 0.22-0.45A
Input Power: Win = 4.8W
Backlight ON / OFF control: Von = 2.4-5.0V Voff = 0-0.7V
Output voltage: Vout = 650V
Output frequency :40 - 60KHz
Turn on the lights voltage: Vopen = 1100-1700V
The above parameters can vary with the use of different screens.
Wide mouth / narrow mouth has applied to 7-inch, 10.4-inch and 12.1-inch digital photo frame, portable DVD or laptop LCD 7 inch -15 inch lamp 6.0 ??mA. And there is an open circuit, short-circuit protection function automatically.
