Network Recorders MC350 & MC350H

The meter is intended for monitoring and measuring electrical quantities of single and three-phase electric energy system. It measures true TRMS value according to the principle of fast sampling of voltage and current signals. A built-in microprocessor calculates measurands (voltage, current, frequency, energy, power, power factor, phase angles, etc.) from the measured signals.

It records energy like the electricity meter in all four quadrants in up to four tariffs.

Since it also measures active and reactive power in all directions it can provide data about power direction (like ANSI code 32).

By using input/output modules it is possible to use meter for process control. Meter supports 2 optional I/O slots ready for use with double input or output modules. Available options are analogue output, digital output (open collector (SO) or mechanical relay), or tariff input. The digital output can be used as pulse or alarm output.

Alarms are a useful tool for fast detection of exceeded parameters, monitoring proper magnitude level and notification in combination with alarm (relay) outputs. Thus function can be used for secondary over/under voltage/frequency protection, overload protection switch...
Internal memory (8MB) is used for the recording of real-time measurements and alarms, all equipped with a time stamp.
Various types of communication modules are available. Serial RS485, M-Bus can be used for connecting device in to the network, standard USB and serial RS232 for connection of the device to computer or controller and service USB communication (not galvanic separated) that can be used for a fast set-up without need for auxiliary power supply.
Available combinations, supported functions and types can be seen in the options table.

Special “ship version” is available, certified by Bureau Veritas.
