Didactum AC Power Sensor

A stable power supply is the foundation of every IT infrastructure. The Didactum AC Power Sensor is specifically designed for monitoring electrical supply in server rooms, data centers, and critical infrastructures. It reliably detects undervoltage, overvoltage, and complete power failures, triggering immediate alerts. By doing so, it protects systems against downtime, data loss, and costly consequential damages.

Importance of AC Power Monitoring

In data centers and server rooms, even minor voltage fluctuations can have severe consequences. The AC Power Sensor ensures:

• Reliable real-time monitoring of supply voltage
• Early warning in case of voltage variations
• Improved system availability through immediate response

From UPS systems to cooling units and switches – the sensor ensures reliable monitoring of the power supply for all critical devices.

Integration & Installation

Installing the AC Power Sensor is extremely simple:

• Plug & Play: just plug into a standard 230V outlet
• Connection: sensor cable to a free port of the Didactum monitoring system
• AutoSense: automatic detection and configuration in the web interface
• Cable length: extendable up to 100 meters for flexible placement

Using the Didactum web interface, administrators can define custom alarm thresholds and automated response actions, such as switching relay contacts.

Alerts & Network Connectivity

In case of voltage disturbances, the AC Power Sensor immediately triggers customizable alerts:

• E-mail notifications
• SMS alerts via GSM/LTE gateway
• SNMP traps to monitoring solutions such as Nagios, PRTG, Zabbix, or OpenNMS
• Relay actions: automatic activation of emergency lighting, sirens, or switching to backup power sources

Typical Applications

• Server room monitoring: continuous power supply control for IT racks and cooling systems
• Data center security: real-time monitoring of voltage quality and power outages
• UPS systems: monitoring of incoming AC voltage to protect against failures
• Telecom stations: ensuring stable power at base infrastructures
• Industrial power monitoring: safeguarding machines, controllers, and automated production systems
• Building management: integration into BMS for comprehensive energy monitoring
• Critical infrastructures: application in laboratories, hospitals, and power facilities
