System Protection:

Protection Features:

If the power supply latches into a shutdown condition due to over-current, over-voltage or short-circuit, the power supply will return to normal operation only after the fault has been removed and the power supply is turned off for 30 seconds or the AC power cord has been removed for 30 seconds.

Over-Current Protection:

The power supply DC outputs are protected from supplying current above the maximum ratings and when output power is between 100-150% of rated specification. With the exception of the +5VSB output, all DC outputs are latched of in the event of an over-current condition.

Over-Voltage Protection:

The over-voltage sense circuitry and reference reside in packages that are separate and distinct from the regulator control circuitry and reference. No single point fault is able to cause a sustained over-voltage condition on any or all outputs. The power supply provides latch-mode over-voltage protection as follows:
+3.3V output is between 3.6-4.2V
+5V output is between 5.8-6.3V
+12V output is between 14.0-17.0V

Short-Circuit Protection:

The power supply DC outputs are protected from damage due to faults, when any output shorts to ground. In the event of a short-circuit on any output , all outputs shall be disabled and remain disabled until the short condition is removed and the power supply is powered off and back on.

 

Safety & Agency Approvals:

TUV, UL, CE, CB, FCC and BSMI.
