Product Information
Full details
The Eltako DC Power Supply (12V, 12W) is designed for industrial control and automation systems, offering reliable 12V DC power ideal for DIN rail installations. Its primary benefit is stable, short-circuit-proof power delivery in a compact, modular format. A key consideration is its 8W bus system power limit, which may necessitate additional units for higher demands.

FAQs
What is the primary application for this power supply?
This power supply is primarily designed for industrial control and automation systems, particularly for DIN rail installations where a stable 12V DC output is required.
Can this power supply power devices that draw more than 1A?
No, the maximum output current for this unit is 1A. Exceeding this limit may cause the unit to shut down or fail.
What is the significance of the 8W bus system limit mentioned?
When used in conjunction with the Eltako series14 bus system, it indicates that individual segments of the bus system (e.g., fed by a divider bridge) should not draw more than 8W of power. If a segment requires more, additional power supplies will be needed.
Does this unit come with power cords?
This unit is designed for hardwiring into an electrical enclosure and does not typically come with power cords. It uses screw terminals for AC input and DC output connections.
What is the standby power consumption?
The standby power consumption is very low, rated at only 0.2 Watts.
How is this unit mounted?
The unit is designed for rail mounting, specifically for standard 35mm DIN rails, and has a width of 18mm (1 modular spacing).
Is this power supply protected against voltage surges?
While it features short-circuit protection, specific surge protection details are not provided in the standard specifications. It is recommended to use appropriate surge protection devices in environments prone to electrical surges.
Troubleshooting
No output voltage
Verify that the AC input voltage is correctly connected and within the specified range (230V AC). Check for any loose connections on the input or output terminals. Ensure the unit is not overloaded beyond its 12W/1A capacity.
Unit overheats
Ensure the unit is installed in a well-ventilated area and not in an enclosed space without airflow. Check if the connected load exceeds the 12W rating. Verify that no components are short-circuited.
Intermittent power or unstable output
Check for loose wiring connections. Ensure the AC input power source is stable. If multiple devices are connected, verify that the total current draw does not exceed 1A. Consider if the series14 bus system power limit of 8W per segment is being exceeded.
Short circuit warning/protection activated
Disconnect the AC power immediately. Identify and remove the short circuit from the connected 12V DC load. After the short circuit is resolved, reconnect AC power. The unit is short-circuit proof and should reset automatically.
Pros and Cons
Pros
- Compact and space-saving design for DIN rail mounting.
- Reliable and stable 12V DC output.
- Short-circuit protection for enhanced safety.
- Low standby power consumption.
Cons
- Limited to 12W total output, potentially insufficient for high-demand systems.
- Requires separate power supplies if the series14 bus system exceeds 8W.
- Not all units may be connected simultaneously if bus system limits are reached.
Setup, Compatibility & Care
Setup:
- Ensure the power supply is disconnected from any power source.
- Mount the unit onto a standard 35mm DIN rail using the integrated clip.
- Connect the AC input voltage (230V AC, 50Hz) to the appropriate screw terminals.
- Connect your 12V DC devices to the secondary output terminals (12V and GND).
- Utilize the included isolation bridge (TB14 1 DE) and spacer (DS14) as needed for your specific installation configuration.
Compatibility:
- This unit is designed for standard 230V AC mains power.
- It provides a 12V DC output suitable for low-voltage electronic equipment.
- For use with the Eltako series14 bus system, total power consumption per segment should not exceed 8W if multiple units are powered from the same bus.
Care:
- Keep the unit clean and free from dust accumulation, especially around ventilation openings.
- Use a dry or slightly damp cloth for cleaning; avoid solvents or abrasive materials.
- Ensure the unit is installed in a well-ventilated area to prevent overheating.
- Regularly check connections for security and signs of wear.
