DC Load Regulation and AC Ripple

12/04/2015 - 10:54

Testing Methodology Establishing an accurate load is critical to testing and evaluating a PC power supply.  PCPerspective’s power supply test bench can place a precise DC load on the PSU under test.  Each power supply is tested under...

A Detailed Look

Differential Temperature and Noise Levels

11/17/2015 - 10:40

To simulate a demanding environment, some of the warm exhaust air from the PSU under test is recirculated back to the intake through a passive air duct, which allows the PSU air inlet temperature to increase with load, up to 40°C.   The...

Efficiency

11/17/2015 - 10:37

Efficiency is defined by the power output divided by the power input and is usually expressed as a percentage.  If a PSU were a 100% efficient (which none are) 600 watts of AC power going in would result in 600 watts of DC power coming out (with no...

AC Ripple and Noise on the DC Outputs

11/17/2015 - 10:34

The amount of AC ripple and noise present on the DC outputs was checked using a digital oscilloscope.  This AC component may be present in the KHz range where most switching power supplies operate or it may be more prevalent at the 60 Hz line...
