- Duty cycle : 6hours ON, 2hours OFF
- Ambient Temp. : 25 ± 2- Humidity : prevailing condition
3.2 Life/Power On Hours
The power supply must be designed to operate for 40,000 power on hours.
About 5 years at an ambient temperature of 25
3.3 Burn-in Test Condition

2) The internal chamber temperature should be displayed with real-time at outside.
If impossible, must supervise after install a thermometer logger.
3.4.2 Test
1) The test operating time standard is refer to Table 10 and after more than 2 times power
on/off test, have to check something wrong in a power supply before test end.- On time: 10sec, Off time: 10sec
2) Normally, the test load condition is 80% of written max load at a product specification.
