2013/05/16 5. Turn On Delay Time

Turn on delay time will be less than 3 seconds at full load. Turn on delay time is measured as the delay between input voltage being applied at 0o phase angle and when the outputs arrive within 10% of their operating value. Turn on delay time is measured using an input voltage of 90VAC(rms) and input frequency of 60Hz.

Test Conditions: Input: 90Vac(60Hz) Output: +19V=3.42A

Ambient Temperature : 25℃

Test Result: PASS

2013/05/16 6. Holdup Time

Holdup time refers to the time it takes for a loss of input voltage to propagate through the power supply and affect the output voltages. Holdup time spec must be met at 100Vac input line voltage and maintain minimum half AC cycle. Holdup time shall be measured by monitoring the output voltages and measuring the time it takes for the first affected output voltage to pass through the lower bound of the regulation threshold after input power to the converter is removed. The initial conditions of loading and input voltage are max load and minimum operational line input. The holdup time is measured by triggering an oscilloscope on the loss of input voltage while monitoring the conditions of the output voltages.

Test Conditions: Input: 100Vac(50Hz) Output: +19V=3.42A

Ambient Temperature : 25℃

Test Result: PASS

2013/05/16 7. Over Current Protection The supply shall be designed with appropriate output over current protection. This protection shall be activated in the event of a short or long-term condition during which one or more of the output current load increases such that the primary current exceeds a predetermined limit. The primary shall limit the total power without inflicting any damage to any internal supply components and shall be reversible pending removal of the cause of the condition and without any user intervention. This protection shall be activated within 130% to 180% of maximum load.
