SMZ 33 analyzer
Panel measuring and registering instruments with internal archive, built-in electricity meter, optional remote communication
SMZ 33 universal power meter and datalogger is ideal for monitoring and recording (data logging) of voltages, currents, power factors, frequency, powers, harmonic distortion of voltage and current, energies etc in three-phase LV, HV, VHV grids. It can also measure and record temperature and state of its inputs/outputs.
All measured values are stored in the instrument and can be later downloaded for processing using a remote communication line and the ENVIS application. SMZ is larger (144x144mm) panel mounted analyser. It has a high contrast LED display suitable for rough environments and precise energy consumption monitoring with preriodic reading capability = stores load profiles among other information.

Feature Description
These instruments are suitable for monitoring and recording voltages, currents, power factors, powers, electric energy, TDH, harmonic components and temperatures in low-, high-, possibly very-high-voltage three-phase mains.
Up to three voltage inputs of nominal value up to 440 V AC, three fully isolated 1-ampere / 5-ampere AC current inputs (from measuring transformer outputs) and one resistor thermometer with a 4-20 mA output can be connected. Two relay outputs with programmable function can be used.
Built-in real time counter can be synchronized through appropriate synchronization input. Two pulse outputs can be programmed for active or reactive power transmission. Data measured and recorded into the instrument memory can be visualized and further processed on PC after transfer through serial link (RS - 232, RS - 485).
