17. EFFICIENCY
80% minimum at 220V AC input voltage and full load.
18. RELIABILITY AND QUALITY CONTROL
16.1 MTBF
When the device is operational within any of the limits of this specification the
MTBF shall be at least 30,000 hours at 25 ..
16.2 BURN IN
The device will be performed a minimum of a 4 hours burn in at 40 . under
80% load on all power supplies.
19. SAFETY
17.1 Leakage current less than 0.35mA 220Vac 50Hz.
17.2 Dielectric Strength Test
Withstand AC 3750V, 50Hz, 5mA at 1 minutes tested for primary to ground.
17.3 Insulation Resistance: 50M ohm at 500Vdc (P to S).
Primary to Secondary : 50 Mohm at 500Vdc.
20. FAULT CONDITION TEST
Damage to the device must not occur such as fire, smoke, break, and molten
metal in equipment.
21. IMPORTMANT
Do not attach a conducting tape to lamp connecting wire, if the lamp wire attach
to conductive tape, TFT-LCD module have a low luminance and the inverter has
abnormal action because leakage current occurs between lamp wire and
conducting tape.
If the display arrangement is less friendly such as the asymmetrical wiring forces
unequal losses and the lamps receive imbalanced current. Even with identical
lamps, illumination may not be balance.
