Didactum DC Voltage Sensor

The Didactum DC Voltage Sensor is a professional measuring instrument for direct current voltage monitoring in server rooms, data centers, and critical infrastructures. With ranges from 0–4V, 0–5V, 0–10V, 0–15V, and 0–75V, it reliably supervises power lines of servers, UPS systems, battery systems, or photovoltaic plants in real time. Undervoltage, overvoltage, and outages are detected early and immediately reported to the Didactum monitoring system.

Importance of DC Voltage Monitoring

Server rooms form the foundation of digital business processes. Even minor voltage deviations can cause downtime, data loss, or hardware damage. With the Didactum DC Voltage Sensor, the power supply is permanently monitored. The system notifies administrators instantly via:

• E-mail notifications
• SMS alerts via LTE/GSM modem
• SNMP traps to common monitoring tools (Nagios, PRTG, Zabbix, OpenNMS)
• Relay actions such as switching alarms or backup power sources

Use in Critical Infrastructures

The DC Voltage Sensor offers wide applicability – not only in IT, but also in industry and energy management:

• UPS supervision: monitoring charge and discharge voltages
• Battery systems: securing optimal charge cycles and extended service life
• Photovoltaic monitoring: analysis of PV panel output voltage
• Critical infrastructures: application in power facilities, telecom, and healthcare
• Building technology: integration into BMS for HVAC and energy optimization
• EV charging stations: supervision of charging cycles for vehicle batteries
• Industrial automation: power stability checks for control and machinery
