The LSP-500VARC High Precision Pure Sine Wave AC Power Supply has the characteristics of good output waveforms, low harmonic, high accuracy, integrated source and meter. With output short-circuit, over-current, over-voltage, over-power, over-temperature alarm protection functions. It can communicate with LISUN LSG series goniophotometer, LPCE-2 high precision integrating sphere spectroradiometer system, LSRF-3 Lamp Start, Run-up Time and Flicker Test System و LS2090 LED Power Driver Tester via RS-232/RS-485 interface.

P.S. LSP-500VARC and LSP-1KVARC are the update versions with big LCD screen. The LSP-500VARC-Pst and LSP-1KVARC-Pst are according to IEC TR 61547-1:2020, IEC61000-3-3, IEC 61000-4-15 and IEEE 1453 Pst programmable function. It can work with LISUN LSRF-3 Lamp Start, Run-up Time and Flicker Test System to test Pst LM(I) parameter.
