Didactum DIN AC Power Sensor

The Didactum DIN AC Power Sensor is a key component for server room monitoring, data center security, and infrastructure management. It reliably monitors undervoltage, overvoltage, mains fluctuations, and power failures in the range of 90 to 240V AC. This energy management sensor ensures maximum operational safety in IT environments, industry, and critical infrastructure.

Importance of AC Voltage Monitoring

Server rooms and data centers require a stable power supply. Even minor voltage deviations can cause data loss, server crashes, or hardware failures. The Didactum DIN AC Power Sensor ensures disturbances are detected and reported immediately. Alerts are triggered in real time via e-mail, SMS, SNMP trap, or relay output.

Use in Critical Business Areas

• Server room monitoring: continuous supervision of supply voltage for switches, servers, and cooling units
• Data center security: immediate alerting on unexpected fluctuations or outages
• UPS monitoring: additional protection and monitoring of incoming supply voltage
• Building management: integration into HVAC and energy management systems
• Industrial automation: safeguarding production machinery, controllers, and systems
• Critical infrastructures: applications in power stations, medical facilities, and laboratories

Installation & Integration

Integration of the DIN AC Power Sensor is especially simple:

• Mounting: direct installation on a DIN rail inside control cabinets or distribution boards
• Connectivity: connection via CAN bus to Didactum monitoring systems
• Auto-Sensing: automatic detection and configuration of values
• Cable length: up to 100 meters for flexible placement

Through the Didactum web interface, users can define custom thresholds, alarm types, and logic rules. This makes the DIN AC Power Sensor highly flexible and ideal for integration into building management systems (BMS) and industrial control systems.

Alerts & Monitoring

The DIN power sensor offers comprehensive alerting and control options:

• E-mail: notifications for administrators and facility teams
• SMS alarms: via GSM/LTE gateway
• SNMP traps: full integration with Nagios, Zabbix, PRTG & OpenNMS
• Relay actions: automated triggering of acoustic or visual alarm devices

Typical Applications

• Server rooms: stable supply supervision for IT racks & cooling devices
• Data centers: real-time alarms on outages, reducing downtime risks
• UPS & energy units: monitoring the incoming supply voltage
• Industrial production: mains supervision to protect machinery and controllers
• Building technology: integration as part of energy management solutions
• Laboratories & hospitals: safeguarding critical medical equipment
