Active or Reactive Power Meters EQ
Power meters are electronic meters intended for measuring active or reactive power in single phase or three-phase networks, with balanced or unbalanced load. The accuracy class is 1.5. The scale value depends on primary values of current and voltage.
Technical data
Meters are available with different front frames:
EQ 0307 – 72 x 72 mm
EQ 0207 – 96 x 96 mm
EQ 0107 – 144 x 144 mm
EQ 2307 – 72 x 72 mm
EQ 2207 – 96 x 96 mm
EQ 2107 – 144 x 144 mm
EQ Analogue Power Meters
Their dials can be 90 degrees in the EQ 0x07 and 240 degrees in the EQ 2x07. Ship versions of the EQ 0207and EQ 0107 are available.
Double voltage meters FQ1x08
Double voltage meters FQ1x08 series measure voltages in two networks. Instruments are intended for installation and supervision panels of power distribution stations and transformer stations or wherever two AC voltages are to be measured.
Features
For measurement of AC voltages
Good read-out survey on larger distance
Resistance to mechanical vibrations
Protective cover for terminals (optional)
FQ Double voltage meters
The incorporated moving-iron mechanism measures r.m.s. values of AC currents in frequency range 15 to 100 Hz, independent of curve shape. The front frames of all the instruments measure 96x96 mm.
Meter with Limit Contact MI7350
The MI 7350 can signal minimal and maximal setting limits (MIN and MAX). The meter is provided with two output relays of 600 VA switching power. Setting over or under the limits is displayed with a LED on the meter scale. DC or AC currents or voltages, frequency and temperature can be signalised. It has 90 degrees scale and is available with front frame 96 x 96 mm.
Remote Display RD500
Remote display is very useful for a quick look-up to all measured parameters or to set up the (U)MT5xx measuring transducers without the PC. Navigation keys and graphical LCD display enable remote application and remote display settings. By choosing different RD500 target communication addresses is possible to track measurements and change settings for up to 32 (U)MT5x0 measuring transducers.
Features
Remote application for measuring transducers (U)MT560, (U)MT550, (U) MT540
Network connection for up to 32 transducers
RS485 communication
Universal power supply 48-276V AC, 20-300V DC
Graphical LCD 128 x 64 dots

SQ0214 Synchronization Meter
If you are looking for manually or semi-automatically synchronise generators and bus bars, you have come to the right place. Our synchronization meters are truly unique products. 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, they are also appropriate for mounting on ships. They are equipped with LED diodes, so you can actually see the phase difference. When synchronising conditions are set, the synchronizing relay is activated.
Types
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 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.
WQ Energy Meters with Power Display
Our energy meters with power displays have housing for panel mounting. Some of them can also display momentary power in single and three phase systems with balanced or unbalanced loads.
Technical data
They can have one mechanical energy counter (WQ 0217), two mechanical energy counters (WQ 1217), one mechanical energy counter and one pointer for measuring power (90 degrees – WQ 0207), one mechanical energy counter and one pointer for measuring power (240 degrees – WQ 2207). Furthermore, they are appropriate for power factor measurement.
YQ Power Factor Meters
Power factor meters are intended for measurement of power factor b (cos?) in a three-phase three-wire network with a balanced load of phases or in a single phase network. The accuracy class is 1.5.
Types
YQ 0307 – 72 x 72 mm
YQ 0207 – 96 x 96 mm
YQ 0107 – 144 x 144 mm
YQ 2307 – 72 x 72 mm
YQ 2207 – 96 x 96 mm
YQ 2107 – 144 x 144 mm
Their dials can be 90 degrees in the YQ 0x07 and 240 degrees in the YQ 2×07.
Reed Frequency Meters ZQ1x17
Reed frequency meters 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.
ZQ Pointer Frequency Meters
They can also use two different dials: The ZQ 0x07 with a 90 degree dial and the ZQ 2x07 with a 240 degree dial. Ship versions are available for ZQ 0307, ZQ 0207 and ZQ 0107 pointer frequency meters.
Technical data
Meters are available with different front frames:
ZQ 0507 – 45 x 45 mm
ZQ 0407 – 48 x 48 mm
ZQ 0307 – 72 x 72 mm
