Didactum DC Current Transformer

The Didactum DC Current Transformer, in combination with the DC Connector, is the ideal solution for real-time monitoring of direct currents in the range of ±100A. Whether in server rooms, data centers, UPS systems, photovoltaic plants, or industrial production environments – this solution provides comprehensive protection against faults, overloads, and energy anomalies. With precise measurement, real-time alerting, and seamless integration into the Didactum monitoring platform, it ensures maximum operational safety.

Importance of DC Power Monitoring

Server rooms and data centers depend on a constant and stable power supply. Even small deviations in DC current flow can result in data loss, UPS malfunctions, or hardware damage. With the Didactum DC Current Transformer, discharge and charge currents of servers, battery systems, and cooling units can be continuously monitored in real time. Using the DC Connector, all values are transferred to the Didactum monitoring system for analysis, alerts, and documentation.

Application Areas

• Server room monitoring: precise supervision of DC currents for servers, switches, and cooling equipment
• Data center security: monitoring of critical UPS systems
• UPS monitoring: tracking charge and discharge currents to increase uptime
• Photovoltaic monitoring: current analysis between solar panels, inverters, and battery systems
• Wind energy systems: supervision of DC input/output in feed-in operations
• EV charging stations: DC flow control for electric vehicle charging
• Industrial environments: monitoring motors, machines, and control units

Functionality & Installation

The DC current transformer works with an open-loop principle – it measures currents contact-free directly on conductors without interrupting the power circuit. This makes retrofitting easy and safe. The DC Connector collects the measured values and transfers them to the Didactum IT monitoring platform. Advantages include:

• Simple installation without interrupting operations
• RJ-11/RJ-12 connection to analog ports (A1–A8)
• AutoSense: automatic detection on the web interface
• Scalability: possible extension with additional Didactum sensor modules

Alerts & Integration

• E-mail alerts to administrators
• SMS notifications via GSM/LTE gateway
• SNMP traps for Nagios, PRTG, Zabbix, or OpenNMS
• Relay actions: automatic triggering of external alarm devices

Additionally, all DC current data is logged and visualized within the monitoring platform, enabling analysis, early detection of overload conditions, and energy efficiency optimization.

Advantages of the Didactum DC Current Transformer

• Measurement range: up to ±100A DC
• Contactless measurement for maximum safety
• Real-time monitoring with customizable alerts
• Plug-and-play integration into Didactum monitoring
• Universal use in IT, industry, PV systems, and energy facilities
• Easy retrofitting thanks to the open-loop design
