Product Introduction： The LED steady State I-V tester uses a combination of different types of LED lamp beads as a steady state light source, each type of lamp bead is independently adjustable, and can be used for IV testing of crystalline silicon, perovskite and laminated cells and their corresponding components. The equipment is mainly equipped with light source control system, power supply control system, test system, constant temperature system, infrared temperature probe, reference battery, computer, display and so on. The equipment can realize the standard I-V, V-I scanning mode, with MPPT (maximum power point tracking), I-t (constant voltage) and other test technologies. Can obtain I-V curve, P-V curve, irradiance curve, short circuit current, open circuit voltage, peak power, peak power point voltage, current, constant voltage point current, fill factor, conversion efficiency, series resistance, parallel resistance and other test parameters.
