Tube Light T8 18W - 22W

SPECIFICATION

GENERAL

SCOPE
This Specification defines the performance characteristics of 18W T8 LED tube light.

INPUT CHARACTERISTIC:

INPUT OPERATING VOLTAGE
140VAC-350VAC.
INPUT POWER
18W ± 5%.
INPUT FREQUENCY
50Hz to 60Hz.
INPUT CURRENT
<150mA RMS @140VAC.
EFFICIENCY
>90% at all line conditions.
POWER FACTOR
>0.95 at all line conditions.
THDi.
<15% at all line conditions.
LUMEN OUTPUT
>1800lm.
LUMEN EFFICIENCY
>100lm/W.
CCT
6500K.

OUTPUT CHARACTERISTIC:

OUTPUT VOLTAGE
70V ± 2.0VDC.
OUTPUT CURRENT
240mA ± 10mA Constant Current.
LINE & LOAD REGULATION
± 5%.

PROTECTIONS:

OVER TEMPERATURE PROTECTION
The driver is protected against over temperature. when the junction temperature on the driver chip die rises to 150ºC, the driver will shutdown immediately and will remain switched off until the temperature on die falls to 130ºC.
OUTPUT OVERLOAD / SHORT CIRCUIT PROTECTION
The driver is protected against over load & short circuit. During over load & Short circuit the driver will go to hick up mode and resumes to normal operation on removal of fault condition.
OUTPUT OVER VOLTAGE PROTECTION
In case of output load open the driver output will limit the voltage to safe levels and will work normally when the load is connected back. this will not create any hard failures in the driver.

ENVIRONMENT

TEMPERATURE
Operating Ambient 0ºC to + 50ºC.
Storage -15ºC to +70ºC ambient.
HUMIDITY
Operating 5% RH to 95% RH non - condensing.
Storage 5% RH to 95% RH non- condensing.
