Class S PQ analyzer, meter and data logger, 0.5S sub-meter, optional color graphic display, input, output and communication options, DIN rail mounted, 6 modules
SMC 144 is specially designed for remote monitoring of energy consumption and its quality. The DIN rail display-less design with multiple communication options is suitable for a wide spectrum of automation tasks in modern buildings, remote supervision of the infrastructure and also remote load management. Absence of local panel controls (display and keyboard) limits possibilities for hostile user interaction.
SMC instruments are an ideal and cost-optimized monitor for any modern SCADA system with embedded support for many protocols over serial line as well as Ethernet. It is also natively supported by our free ENVIS application. Its input and output set can be extended with additional IO modules for advanced control functionality.
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).
