Input Current and Voltage Waveforms
This section presents the input AC current and voltage waveforms. The graph displays voltage (blue line) and current (red waveform) over time. The Input AC Current Waveform at 50% Load shows a Total Harmonic Distortion (THD) of 9.75%. The voltage axis ranges from -400V to 400V, and the current axis ranges from -0.8A to 0.8A. Time is shown on the x-axis.
Efficiency and Load Data
The table below details the power supply's performance across various load conditions, including input/output power, DC terminal voltage, DC load current, and efficiency.

Input and Output Power vs. Loading
This graph illustrates the relationship between loading percentage (of rated output power) and power consumption. The 'Input Power' line shows how much power the supply draws from the AC source, while the 'Output Power' line indicates the power delivered to the load. The graph spans from 5% to 100% loading.
Efficiency of the Power Supply vs. Loading
This graph displays the power supply's efficiency (%) across different loading percentages. It shows how efficiency changes as the load increases from 5% to 100% of the rated output power. The graph also indicates efficiency levels corresponding to various 80 PLUS certifications (Ruby, Silver, Bronze, Gold, Platinum, Titanium).
About the 80 PLUS Program
These tests were conducted by a third-party independent testing firm on behalf of the 80 PLUS® Program. 80 PLUS is a certification program to promote highly-efficient power supplies (greater than 80% efficiency in the active mode) in technology applications.
