SMZ 133 Analyzer

Advanced panel meter with large internal archive, built-in electricity meter, optional remote communication and rich set of Input-Output options

SMZ 133 is a new precise multipurpose power meter with data logger function. It measures and records frequency, line and phase voltages, currents, power factors,  powers, unbalances, 64 voltage and current harmonics and its direction, active, reactive and apparent energies and other quantities in the 50/60 Hz three-phase LV, MV and HV grids. It also measures and records input/output states and ambient temperature. It is intended for installation into panel. This instrument has bright LCD display which provides many useful information locally.

SMZ 133 has a broad portfolio of communication options including local USB port, 10/100 Mbit Ethernet or up to two remote RS485 serial lines. With this portfolio it can simply be integrated into more complex systems. It can also serve as a gateway for other instruments and actively collect data from slave instruments (with Modbus Master option). Ouputs can be programmed to control local appliances in energy efficiency or peak demand management systems. All measurement values are continuously measured and recorded at intervals of 10/12 periods (~200 ms) or higher into the local 512 Mb memory.

Device Types

ENVIS application suite provides all features for basic instrument management (configuration, supervision, fw update). It also downloads and archives data from all the supported instruments. import/export, data analysis and advanced reporting of the records is also provided. ENVIS is available free of charge to be used with all our instruments.

Typická instalace aplikace ENVIS

ENVIS.Online system service can be used to implement complex power quality monitoring and/or energy efficienci control and monitoring systems. By using email,  SMS or SNMP all registered users and administrators can be warned upon exeptional situations, malfunction of supply or monitored instruments or it can be used to post periodical analysis/reports.

Additional plugin modules can also add special features or customizations to booth ENVIS and ENVIS.Online in a modular manner. 

Typical installation of ENVIS

 

Optional firmware modules

Voltage and power event cycle data logger module.
  • Ripple Control (Mains) Signals - RCS Module: for measurement, recording and analysis of a ripple control signal. Several formats of the telegram are also supported for decoding.
  • Voltage Events - VE Module: for recording and evaluation of voltage events (SMVQ & SMPQ does include this feature in its default configuration).
  • General Oscillograms - GO module: for detection and precise recording of various waveform distortions. This module records the so called oscillograms of voltages and currents in extended detail, capacity and trigger options into the flash memory.
  • Modbus Master - MM module: in supported instruments with memory it activates new option to record Modbus data from connected slave devices. It can work as a datalogger to NOVAR PFCs as well as to local sub-meters or other Modbus sensors.
  • See: other built-in meters and analysers, portable analysers and data loggers, ENVIS 1.1 for data analysis.
