8.1 Safety Requirement
8.2 Leakage Current
The AC leakage current is less than 3.5mA when the power supply connect
to 264Vac/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 V 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 good turn off delay time ( 1.0 mS Min.) PS-ON/OFF
* T6 : Power hold-on time ( 12 mS Min.)
* 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.
The MTBF of the power should be 100,000 hours min.
10. MTBF
11.1 Input Voltage
Applying 220Vac for 230V model.
11.2 Test Condition
Applying 75% loads for the power supply in 45 (+/-5) oC chamber for 4 hours.
