Multi-functional meter for CATIV environments, class S analyzer and data logger, with color graphic display, precise energy meter, 96x96mm

SMP 133 is a hardened version of SMY 133 power analyzer intended specially for use in smart grids, distribution network automation substations and other types of harsh environments. Measurement inputs are designed for CATIV/300V networks. The instrument is supplied from a safe low voltage (12-24V LVDC) power supply. A proper single- or three-phase power supply for substation use can be also supplied - see our PWR 1 and PWR3 product lines. It measures and records all common electrical parameters, active and reactive energies in quadrants and per phase, per tarif as well as totoal. It can also record transients, evaluate ripple control signals and interact with the substation control system through its IO ports.

It can optionally monitor power quality (with PQ-S module - inter-harmonics, flicker, voltage events), record transients (with GO module) and the ripple control signals (RCS module).

Optional relay or SSR outputs can be programmed to control other equipment based on measured values (useful for fan control, over-voltage/over-current pq relaying etc). Impulse outputs can also forward metered values as an S0 output. USB port provides quick, easy and reliable means for configuration and data acquisition. Optional serial or Ethernet interface (with web server, modbus TCP, SNTP, DNS, SNMP, DHCP...) allows it to be remotely managed via the ENVIS application. Firmware module is also available with support for IEC-104 substation automation protocol. In combination with ENVIS.Online service, e_get tools or embedded library (.NET core, C/C++ for Windows/Linux) its actual values can be also periodically downloaded and stored to a file or remote SQL database for further processing and analysis.
