    Description

    The LSP-500VARC High-Precision Pure Sine Wave AC Power Source delivers exceptional waveform quality with low harmonic distortion and high measurement accuracy, featuring an integrated source and meter configuration. Comprehensive protection functions include output short-circuit, over-current, over-voltage, over-power, and over-temperature alarm systems.

    This instrument interfaces via RS-232/RS-485 communication ports with LISUN LSG series goniophotometers, LPCE-2 high-precision integrating sphere spectroradiometer systems, LSRF-3 Lamp Start, Run-up Time and Flicker Test Systems, and LS2090 LED Power Driver Testers.
