Split Meters (DRDHC) 1/3 Phase
Three Phase Pole-Mounted Meter
Description
AKU S30 - Split-meter of electric energy three-phase static bidirectional direct switching. It is designed for measuring electrical energy (active and reactive, forward and reverse), estimating instantaneous active, reactive, apparent power and a number of other parameters in three-phase four-wire AC networks with a voltage of 3x230/400 V. Allows centralized data collection on 0.4 kV lines or on an 868 MHz radio channel. The AKU S30 meter is mounted directly on the power pole using a specially designed bracket. The AKU R10 user display is used to display information about the measured parameters.
