Range of digital multifunction timers and monitoring relays. The main attention was pointed to reliability, preciseness, measurement accuracy and long life time. All produced relays are based on the microprocessor technology, which assures the best quality and operation accuracy. Measured signals are analysed by DFT (Discreet Fourier Transformation), which separates disturbances, noise and high harmonics influence from fundamental signal. Thanks to DFT, values for further calculation are more precise and reaction is more accurate comparing to the standard analogue relays. BMR relays are equipped with many features like, for example, relay status and optical fault identification by logic LED signalization. For fast installation all terminals are labelled so that labels are visible in mounting position. These features make installation and operation easier and help to user identify possible network faults.
