8.1 Safety Requirement

8.2 Leakage Current

The AC leakage current is less than 3.5mA when the power supply connect to 253Vac/50Hz .

8.3 Insulation Resistance

The insulation resistance should be not less than 30M ohm after applying of 500VDC for 1 minute.

8.4 Dielectric Voltage Withstand

The power supply shall withstand for 1 minute without breakdown the application of a 60Hz 1500V AC 
voltage applied between both input line and chassis (20mA DC cut-off current). Main transformer shall 
similarly withstand 3000Vac applied between both primary and secondary windings for a minimum of 
one minute.

8. Product Safety

A TTL compatible signal for the purpose of initiating an orderly start-up procedure under normal input 
operating conditions. During power up, this signal is asserted ( low ) until +5V is under regulation and AC 
reaches min. line specification range. After all voltage are going appropriate level, the system may have a 
turn on delay of 100mS, but no greater than 500mS. During power off the signal should go to low level 
before +5V is out of regulation. The low level is 0 to 0.8V and high level is 4.75 to 5.25V. The " Power Good "
signal can drive up to 6 standard TTL loads.

* T1 : Turn on time ( 2 sec. Max.)  

* T2 : Rise time ( 

≦

 20mS Max.)

* T3 : Power good turn on delay time ( 100 < T3 < 500 mS )
* T4 : Switch on time (0.5 sec. Max.)
* T5 : Power hold-up time (16 mS Min.at 80%load)
* T6: Power good turn off delay time ( 1.0 mS Min.) 80%load
* Power on-off cycle : 
When the power supply is turned off for a minimum of 2.0 sec. and turn on again, the power good signal 
will be asserted.
