Combined AC power supply and power analyzer
GET completely stable AC feed to your light source
AC mains feed is not always stable and does not always stay at the rated voltage and frequency. To comply with measurement standards (such as IES LM-79 and CIE S 025), your devices must be tested under rated conditions with specific tolerances.
LabPower will provide a pure sine wave feed to your light source while maintaining the voltage and frequency conditions.
ADvanced power analyzer functions
Every Viso light measurement system includes a basic built-in power analyzer.
The LabPower analyzer bypasses the built-in analyzer and adds more accuracy and specific features that makes the test circuit and analyzer uncertainties comply with IES LM-79 and CIE S 025 requirements.
Advantages of a combined instrument
Combining a power supply with a power analyzer provides several advantages:
Connect to any Viso light measurement system
