Table 3. Inverter Electrical Characteristics

Notes :

1. The specified current and power consumption are under the typical supply Input voltage, 24.0V.

The ripple voltage of the power supply input voltage is under 0.5 Vp-p.

Inrush current of the power supply input current is under +10% of the typical current

2. Specified values are for a single lamp which is aligned horizontally.

The life is determined as the time at which luminance of the lamp is 50% compared to that of initial

value at the typical lamp current on condition of continuous operating at 25

± 2°C.

Specified value is when lamp is aligned horizontally.

3. Electrical characteristics are determined after the unit has been ‘ON’ and stable for approximately

2Hrs in a dark environment at 25 °C

± 2°C.

4. Burst mode is controlled by TV system

5. Rush current is determined at turning on after the unit has been ‘OFF’ for 2Hrs at 25 °C

± 2°C.
