SilverStone ST75ZF [12/16] St75zf manual 12

6.3 Production Line Testing

100% of the power supply production must have the following test performed. Each power

shall be marked indicating the testing was done and passed. Typically this is done by stamping

or labeling the power supply with "Hi-pot test OK".

6.4 Hi-Pot Testing

Each power supply must be Hi-pot tested according UL and TUV requirements, Minimum

typical testing voltage for Hi-pot testing are 1500Vac or 2121Vdc. However depending on the

power supply design the testing voltage May be higher. If higher the power supplies shell be

at the higher value.

6.5 Ground Continuity Testing

UL and TUV require that each power supply ground is tested, to ensure there is continuity

between the ground inlet of the power supply and the power supply chassis. This can be

performed with an ohm meter, or an electronic circuit that lights up and illustrates the ground

has continuity.

Based on EN50116, ERG or TUV require that each power supply ground id tested with a

25Amp ground test.

7. Reliability

7.1 Mean Time Between failures (MTBF)

The MTBF of the power supply shall be calculated utilizing the Part-Stress Analysis method

of MIL217F or Bellcore RPP. The calculated MTBF of the power supply shall be greater than

100,000 hours under the following conditions:

Full rated load

120V AC input

Ground Benign

25℃
