The 12 V/1 A power supply for CAN devices from Didactum is a robust and efficient solution for powering modern CAN‑bus‑based sensor and expansion systems. It delivers the required power to reliably supply up to twelve additional CAN sensors and CAN expansion modules, making it an essential component in complex automation and monitoring infrastructures.

With an input voltage of 12 V DC and a current of up to 1 A (max. 2 A), the power supply ensures stable voltage delivery even in long CAN‑bus chains. It is specifically designed for industrial continuous operation and supports flexible network expansion through its Daisy‑Chain technology.

Optimal power distribution for extended CAN‑bus topologies

In professional monitoring or automation environments, the CAN power supply seamlessly connects groups of up to twelve devices within a CAN‑bus chain. When more than twelve sensors or modules are in operation, an additional power supply becomes necessary.

This unit provides exactly that – it supplies additional power for every further group of twelve CAN devices, ensuring continuous operation for up to 32 sensors or extensions across the entire system.

• Supplies additional CAN extensions in Daisy‑Chain topology
• Maximum compatibility via RJ11 CAN‑port connection
• Supports up to 15 sensors per power supply
• Simple cascading of multiple power units for larger systems

Networking via Daisy‑Chain technology

The compact 12 V/1 A power module integrates easily into existing CAN structures. Standardized RJ11 CAN ports at both input and output ensure fast, secure connectivity. This Daisy‑Chain connection enables linear chaining of multiple modules to operate large, stable CAN networks.

LED status display and diagnostics

For easy status monitoring, the power supply is equipped with a green LED indicator showing active voltage. This allows rapid detection of potential issues in the CAN network and minimizes maintenance time.

Rugged design for industrial environments

The Didactum CAN power supply is specifically designed for industrial applications with demanding environmental requirements:

• Operating temperature: –40 °C to +100 °C
• Humidity: 0 – 95 % RH (non‑condensing)
• Housing: Compact (68 × 67 × 26.2 mm) and durable
• Weight: only 190 g – ideal for flexible installation

This makes the power supply ideal for demanding applications in factory automation, building systems, and other industrial sensor networks.

Installation and setup

The compact size and straightforward connection method allow for quick integration. The unit can be installed as a desktop device or wall‑mounted. When used with Didactum monitoring systems, no additional configuration is required – simply connect, and the CAN devices are automatically powered.

Safe and compatible

Manufactured in the European Union and tested to European quality standards, the power supply complies with industrial application requirements. Its international HS Code 8504 40 90 confirms its classification as a reliable industrial power unit.

Typical applications

• Factory automation: Power supply for extended CAN sensor networks.
• Building automation: Expansion of existing CAN‑based measurement systems for climate or security sensors.
• Data centers: Stable voltage supply for CAN‑based monitoring extensions.
• Environmental monitoring: Continuous operation of distributed sensor groups over long distances.

Extended power supply for reliable CAN communication

The 12 V/1 A power supply for CAN devices from Didactum is an indispensable addition to large‑scale CAN‑bus installations. With its rugged design, LED status display, wide environmental tolerance, and simple Daisy‑Chain networking, it provides a safe, durable, and flexible power solution for all industrial monitoring applications.
