SMP-BX and SMPQ-BX
Portable power quality analysers - with graphic dipsplay, large internal memory, builtin electricity meters - simple installation and current measurement with flexible CTs
Analysers of electric network parameters SMP-BX 300, SMP-BX 340, SMPQ-BX 300 and SMPQ-BX 340 are a measuring and data logging instruments for single- and three phase low voltage (up to 230/400 VAC) distribution networks in substations, switchgear boxes, power cubicles or directly at the consumers premises such as smart buildings, hospitals, industrial infrastructures etc.
Core of the instrument is a standard SMP or SMPQ -F analyzer. Its features and functions closely corresponds to the -BX enclosure version. Another portable instrument with different enclosure is SMP-CA.
SMP-BX 300 and SMPQ-BX 300 are a three phase voltmeters (does not measure UN). SMP-BX 340 resp. SMPQ-BX 340 are additionally equipped with 4 current inputs. It supports measurement of currents up to 3000AAC with a flexible Rogowski coil current probe. This instrument measures 4 currents, single and three phase powers, power factors and electrical energy.
SMPQ-BX instruments are a fully featured power quality analysers with support for interharmonics, flicker indices (Pst,Plt), record of voltage events and weekly power quality evaluations according to EN 50160.

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.
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.
