Note: 上升時間為輸出電壓從10%上升至90%的時間。

The rise time measured is when the output voltages rise from10% to 90% of

specified output voltage Vout observed on the channel waveform.

4.5. 動態響應時間 Dynamic load response time

The following shall apply to the 3.3 V, 5 V, and 12 V outputs:

Output voltage for each output shall recover to within 5 % of its steady state level in less

than 1 ms under the following conditions:

AC Input Voltage: 90VAC ~ 264VAC

Repetition rate of 100Hz with 50 % duty cycle

4.6. 遠端開關控制 Remote on/off control

The main outputs of this power supply (3.3V,5V,12V,-12V) shall be energized when input

signal*PSON is active. *PSON is an active low TTL compatible signal referenced to the +5V

standby common. This input signal shall be an open collector signal capable of sinking a

minimum of 1.6mA. When *PSON becomes inactive, the main outputs shall be disabled.
