9. POWER GOOD SIGNAL
8.1 Safety Requirement
6.3.1 Sweep and resonance search for each of X,Y,Z, axis at the sweep.
TUV, UL/c-UL,CB
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.
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 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.

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.
