These products are intended for marine use and include synchronization meters, digital multimeters, and analogue instruments. The synchronization meters measure phase differences between generators and bus bars to enable manual or semi-automatic synchronization. The digital multimeters measure voltages, currents, power quantities, and include communication capabilities. The analogue instruments include pointer frequency meters, reed frequency meters, and meters for measuring AC voltages and currents.

SYNCHRONIZATION METERS
DIGITAL MULTIMETERS WITH COMMUNICATION
ANALOGUE METERS
These products are intended for manually or semi-automatically synchronising generators and bus
bars. They measure phase differences between generator and bus bar, voltages and the frequencies
of the two systems. They can replace up to five instruments, occupying less space and giving you
more information, for a lower price. Furthermore, they are equipped with status output especially
appropriate for ship mounting. They are equipped with LED diodes, so you can actually see the phase
difference. When synchronising conditions are set, the synchronizing relay is activated.
If you are interested in the phase difference between generator and bus bar, select SQ 0204. If you
also want to have information about voltages and frequencies of the systems, select SQ 0214.
The ZQ 1207 or ZQ 1208 two-system frequency meter is used for measuring frequencies in two networks. The FQ 1207 or FQ 1208 double voltage meter
measures voltages in two networks. The front frames of all the instruments measure 96x96 mm. Ship versions of the SQ 0204, ZQ 1207 and FQ 1207 meters
are available on request.
The SQ 0201 phase sequence indicator is intended for determining phase sequences in a three-phase network, from 200 V to 500 V and from 50 Hz to 60 Hz.
The indicator is provided with two built-in glow lamps indicating L1, L2, L3 phase sequence.
MT440 are intended for measuring and monitoring singlephase or three-phase electrical power
network. They measure RMS value by means of fast sampling of voltage and current signals, which
makes instruments suitable for acquisition of transient events. A built-in microcontroller calculates
measurands (voltage, current, frequency, energy, power, power factor, THD phase angles, etc.) from
the measured signals.
Alarm (relay) outputs can be used as a supervisory functions with user defined limit lines to all
measured parameters. Precise energy measuring in all 4 quadrants with 4 configurable counters can
be used as a secondary energy metering device.
The meter MC350H is intended for monitoring and measuring electrical quantities of single and three-phase electric energy system. It measures true RMS
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.
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. Digital output can be used as pulse or
alarm output.
Meters for AC Voltage or Current with Moving Iron FQ are intended for measurement of AC
currents or voltages of frequencies from 15 Hz to 100 Hz. They measure rms values independently on
the signal form of current or voltage.
Reed frequency meters ZQ are intended for measurement of frequencies in the range from 45 Hz to
65 Hz. Two-system reed frequency meters are intended for measurement of two frequencies in the
system for synchronisation. Their class is 0.5.
Pointer frequency meters ZQ are intended for measurement of frequencies in the range from 45 Hz
to 65 Hz. The accuracy class is 0.5.
