When performing light measurements on light sources, it is important to have a stable and controlled electrical supply. The flux can be highly influenced by a variable voltage supply (variations in amplitude, harmonic distortion…). Most norms require a perfect sinusoidal voltage supply with a specific amplitude and frequency for light measurements.
Several controlled power supplies are available in the Light & Lighting Laboratory.
Voltage supply Agilent, type 6813B
- Maximum ratings: 1750 VA, 300V rms, 13 A rms, crest factor 6 TEST
- Frequency range: DC and AC from 45 Hz to 1 kHz
- Possibility to create a specified non-sinusoidal wave form.
- Possibility to create controlled voltage drops, transients…
