Measuring transducers MT 4xx are intended for measuring and monitoring single phase or three-phase electrical power network. MT 416 Programmable AC Voltage Transducers MT 418 Programmable AC Current Transducers MT 440 Multifunctional Transducers
The meters are intended for measuring, analysing and monitoring single-phase or three-phase electrical power networks. The meter measures RMS value according to the principle of fast sampling of voltage and current signals. A built-in microprocessor calculates measures (voltage, current, frequency, energy, power, power factor, THD phase angles, etc.) from the measured signals.

Digital Meter With LED Display Digital meters with LED display enable fast and accurate survey of electric quantities and are convenient for industrial use as well as for the production and distribution of electric energy. They are panel mounted and enable measurement of TRMS values of electric quantities.
Energy Meters With Power Display With Power Display, display instantaneous power in single or  three-phase systems with balanced or unbalanced load. 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.
Analogue Meters Active or Reactive Power Meters 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.
Power Factor Meters Power factor meters are intended for measurement of power factor (cosϕ) in a three-phase three-wire network with a balanced or unbalanced load or in a single phase network. The accuracy class is 1.5.
Pointer frequency meters are intended for measurement of frequencies in the range from 45 Hz to 65 Hz.
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.
Meter With Limit Contact 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.
TAP Position Indicators monitor the voltage Tap on a transformer, hoist or valve position etc.  It employs a bridge system, using a 400Ω or 50Ω  per step. The scale is entirely linear and inter-changeable.
Meters for AC Voltage or Current with Moving Coil and a Rectifier Meters with a moving coil and a rectifier are intended for measurement of AC currents or voltages where a linear scale is required, in the frequency range from 40 Hz to 65 Hz (higher frequency range on request).  The scale is interchangeable. The accuracy class is 1.5.
Meters for AC Voltage or Current with Moving Iron Meters with a moving iron 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.
Bimetal maximum current meters with a bimetal measuring system are intended for testing the thermal load of transformers, cables, electrical machines, etc. They indicate average rms current value in a setting period of 8 minutes (on request 15, 20 and 30 minutes for the MQ0207 and the MQ0307). The accuracy class is 3 and the meters are provided with an interchangeable scale. Meters in the size of 96 x 96 mm with a protecting  transformer are also available on request.
Combined Bimetal Maximum Current Values Combined bimetal maximum current meters are provided with a built-in bimetal system and a system with a moving iron. The meters are intended for testing momentary and thermal load of transformers, cables, electrical machinery, etc. Meters with dimensions of 96 x 96 mm with a protecting transformer are also available on request. The accuracy class for average rms current value is 3, and for momentary value 1.5. The meters are provided with an interchangeable scale.
Shunts = 50 Millivolt + 60 Millivolt.
Current Transformers Current measuring transformers are used for measuring Primary AC currents. The secondary current is 5A or 1A, rated frequency from 50 Hz to 60 Hz.

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.
