4.1. Over Current Protection

This power supply shall have current limit to prevent the +5V, +3.3V, and +12V outputs

from exceeding the values shown in table 14. The current limit shall not trip under

maximum continuous load or peak loading as described in Table 5. The power supply

shall latch off if the current exceeds the limit. The latch shall be cleared by toggling the

PSON# signal or by cycling the AC power. The power supply shall not be damaged from

repeated power cycling in this condition. The -12V and +5VSB outputs shall be shorted

circuit protected so that no damage can occur to the power supply.

4.4. No Load Operation

When the primary power is applied, with no load on any output voltage, no damage or

hazardous conditions shall occur.
