  • Panel | Digital Multimeter | with 3 Current Transformers (CT) | Current | Voltage | Frequency Meter | 3F | 10-250A | 1-500VAC

    Code: ES-SEM-250D

    This digital three-phase multimeter is designed to measure the values of three-phase current, voltage, and frequency. The device has three current transformers (10-250 A), which allow accurate measurement of current and phase voltages (L-L and L-N). The multimeter automatically displays current values without any additional settings, simply by connecting the current transformer. Additionally, the device also shows the phase sequence, which allows checking whether the phase sequence is correct.
