75x60x22,5 mm MONIVOLT This is a device for monitoring the voltage and for protecting electrical devices. It can be used either in industry, business or home applications. It uses the True-RMS* measurement method to monitor the voltage and protect single-phase loads from under- and overvoltage. It also includes an automatic 3-minute timer to prevent the output from turning ON again before this time elapses. This function ensures protection for equipment, such as compressors, that require a minimum stop time after turning OFF. Application example: protection for single-phase electrical equipment. » Product manual

71x28x71 mm PhaseLOG Digital instrument for monitoring and protection of electric plant which can be used either in business or home appliances. It features an real-time clock and datalloger to storage the electric tension data of each main phase in from the power grid in during time periods of time preset by the user. The power supply quality is measured by True-RMS* values besides protect the loads from under and over voltage, angular and modular asymmetry, phase failure and phase sequence. It has a serial communication for connection to Sitrad. Application example: protection of three-phase electric equipaments. » Product manual

71x28x71 mm SwitchLOG It is an instrument for voltage monitoring and protection of refrigerated transport. This instrument protects the refrigeration system compressor from under and over-voltage, modular and angular asymmetry and even phase fault and invertion. It selects the arrangement of motor winding coils using a specific output, such that the motor can receive the local voltage, ensuring the compressor is connected to the correct power mains. If the voltage is 220V, this product powers a contactor the configures the motor coils in connection. It features a digital input to identify whether the system is operating from the diesel generator or the electric power. It has an internal memory (datalogger), which allows recording of the dates and times when the cooling system was connected to the electric power. It has a serial communication for connection to Sitrad.

* True RMS: Is the real and effective voltage value which also includes the voltage generated by high frequency noise in the distributing network (harmonic distortion). This is the actual voltage applied to the connected load (example: electric motor, compressor). This method allows the precise voltage measurement for any type of wave form. Other measurement methods give correct value of applied voltage only for perfect sine wave forms.
