Kerberos - Smart supervisor for rack with NB-IoT modem

Smart supervisor for rack with NB-IoT modem

The KET-RKM-200 is a rack monitoring system designed to monitor all basic rack parameters.

The system allows monitoring of rack internal temperatures and PDU consumption. It also has dedicated inputs for smoke, flood and door opening sensors.

Thanks to X-Monitor technology, each rack can be monitored by a slave unit connected to a single master unit via RS485.

The master unit can be configured to send data to external platforms using internal NB-IoT 3GPP, GPRS, Narrow Band modems or via Ethernet.

Equipped with dual 100-240 VAC power supply and supercapacitor to operate even in the absence of power for the time necessary to send the acoustic signal to the alarm.
Internal Flash memory 256 Kb, F-RAM and RTC for data protection.

It is also equipped with an infrared door opening sensor and temperature and relative humidity sensors to check the status of the device itself.
