EVBOX1 Datalogging

Electrical control panels for single-phase cold rooms
EVBOX1 Datalogging is a range of electrical control panels for single-phase cold rooms with data-logging extension for compliance with the EN12830 standard
Equipped with up to 6 relay outputs, the electrical panels can regulate with great flexibility and energy savings the most varied equipment configurations on the market, including those with management of temperatures as low as -99°C.
The controllers use two relays, rated load 30 A @ 250 VAC, for direct control of high-power compressors and the evaporator fan and they can be adjusted for low and high relative humidity.
Some models have a thermal-magnetic circuit breaker and include a driver for unipolar stepper-type electronic expansion valves. They all have a clock for memorising HACCP alarms and a data-logging extension on an SD card with built-in battery for data recording, even in the event of a power failure.
The user interface consists of a large custom display with decimal point and function icons, with six buttons. It guarantees IP65 frontal protection. The controllers are designed to be wall-mounted, with fixing screws and plugs.
