It is possible to prerecord up to 10 auto dial messages. Configure ESIM252 so that different users would get alerts only important to them or about devices they are responsible for. Choose between auto call or SMS, maybe some will prefer to receive both + status alerts about auto reboots and device faults. For example: get informed when food vending machine is full of coins by getting an SMS, this will help to avoid unnecessary checking, or monitor ventilation system in your shopping center with accuracy. The system reports about electronic devices failures too.

We are offering power factor control relay. Functions: pfr 06pfr 12 is the new range of power factor regulators using on the highest technology and designed for easy and effective regulation. Regulator monitors the power system status and accurately and quickly takes decisions on the connection or disconnection of compensation stages in order to reach the preset target cos phi. Regulator´s microprocessor records system voltage and current consumption of the entire operation via instrument transformer inputs and uses these to calculate the relationship between active power and reactive power in the power system. Regulator calculates the basic harmonic factor of the active and reactive currents using the fft algorithm. Thus precise measurement and control are provided even if the current waveform is distorted by higher harmonic components. Benefits 6 or 12 steps thd measurement alarm output 4 quadrant pfc fcp system (fast computerized program), minimizes the number of onoff operations measuring cos phi, using true rms voltage and current values displays all measurements on one single display connected steps display features designed for easy and intuitive handling by the user parameter setting in run−time totally digital setting and handling technical data supply and measuring voltage: 400 vac (+15−10%), 45−65 hz current measurement circuit: ct, in 5 accuracy of current measurement: 1% accuracy of voltage measurement: 1% accuracy of cos phi measurement: +− 2%, 1 digit display: 1 line x 3 digits x 7 segments + 20 display icons output: relays, max. 250 v, 4 a, ac1 protection degree: ip 55, category iii dimensions: 144 x 144 x 62 mm

Contact protection relays are used in type 821 contact devices. They increase the switching reliability and switching capacity of electromechanical contact devices and lower their contact voltage. Undesired switching operations of contact devices caused by vibrations are significantly reduced by a drop-out delay of 0.5 sec. On the side of the contact they operate with a lower control voltage, however, on the output side they can be highly loaded. Contact protection relays consist of a power supply unit, control unit, switching amplifier and relay output. The contacts are supplied by a control unit with 35 to 40 V clocked DC (i.e. only every hundredth switching occurs under voltage). This enables the optimum contact protection and switching reliability for millions of switching cycles.
