4.1.7. OVER POWER PROTECTION

Total output shall not exceed 220 watts , in the event of an output total power condition on output ,

If the total exceed 150% , the power supply will shutdown and latch off without damage to

the power supply.

4.1.8.POWER GOOD SIGNAL

The power good signal is a TTL compatible signal for the purpose of initiating an orderly star-up

procedure under normal input operating conditions. This signal is asserted (low) until +5Vdc has

reached 4.75 volts during power up. Characteristics:

TTL signal asserted (low state) : less than 0.5V while sinking 10mA.

TTL signal asserted (high state): greater than 4.75V while sourcing 500uA.

High state output impedance: less or equal to 1Kohm from output to common.

POWER GOOD @ 115/230V, Typical (50%) LOAD 100 –500mSec.

POWER FAIL @115/230V, Typical (50%) LOAD 1 mSec. minimum
