For greater flexibility and precision in the control of single-phase cold rooms which require temperatures as low as -99°C for the storage of laboratory products, the EVBOX1 Datalogging range of electrical control panels have 6 relay outputs, 2 of which with rated load 30 A for direct control of high-power loads, and a built-in driver for the management of unipolar stepper type EEVs. Safe against overloads thanks to a thermal-magnetic circuit breaker, they feature strategies which are compliant with the EN12830 standard for data recording in the event of a power failure, as they are equipped with a data-logging extension on an SD card with built-in battery.
