For system integrators, panel builders, and procurement teams in the building automation industry, selecting a power supply is not only about wattage. It also involves cabinet space constraints, standby energy consumption, thermal management, and compliance with international safety standards. In modern smart buildings, every millimeter of DIN rail space is contested by KNX controllers, BACnet gateways, HVAC modules, and IoT gateways—and every milliwatt of standby power adds to the building’s energy footprint.
The TPS060-GP24V, part of the TPS010-100W GP Series distributed by TPS Elektronik, is a high-performance DIN rail power supply engineered specifically for building automation applications. It delivers 24V DC at 2.5A with 60W output power, features <0.3W no-load standby consumption, achieves 87% efficiency, and fits in an ultra-compact 91×71×60mm housing—making it the ideal power solution for energy-conscious, space-constrained building automation control cabinets.
1. The Building Automation Challenge: Space, Energy, and Reliability
Building automation systems are the backbone of modern smart buildings. They integrate HVAC control, lighting management, access control, fire safety, and energy monitoring into a unified infrastructure that optimizes comfort, safety, and energy efficiency. At the heart of every building automation cabinet are the controllers—KNX devices, BACnet gateways, DDC controllers, and IoT gateways—that require stable, clean DC power to operate reliably 24/7/365.
For system integrators and panel builders, building automation control cabinets present three interconnected challenges:
- Space constraints: Control cabinets are increasingly compact, with every millimeter of DIN rail space in high demand. A bulky power supply forces designers to use larger cabinets or sacrifice other critical components.
- Energy efficiency: Buildings account for approximately 40% of global energy consumption. Standby power—the energy consumed by power supplies when the load is inactive—represents a significant and often overlooked source of waste. Energy regulations such as the European ErP (Energy-related Products) Directive increasingly require low standby power consumption from all building automation components.
- Reliability: Building automation systems must operate continuously. Power supply failures can disable HVAC systems, compromise security, or disrupt critical building functions.
These challenges demand a power supply that is compact, efficient, and reliable. TPS Elektronik’s custom DIN rail power supply solutions are engineered to meet exactly these requirements.

3. Low Standby Power: Meeting Energy Efficiency Demands
Standby power—the energy consumed by a power supply when the connected load is inactive—is a critical consideration in building automation. With thousands of power supplies operating in a single commercial building, even small standby losses add up to significant annual energy waste.
The TPS060-GP24V consumes less than 0.3W in no-load mode, placing it among the most energy-efficient DIN rail power supplies available. By comparison, many competing DIN rail power supplies in the same power class consume 0.5W to 0.75W or more in standby.
This low standby consumption delivers several benefits for building automation systems:
- Reduced energy costs: Lower standby power translates directly to lower electricity bills over the life of the building
- Compliance with energy regulations: Meets the requirements of the European ErP Directive and other energy efficiency standards
- Lower heat generation: Less wasted energy means less heat dissipated into the control cabinet, reducing cooling requirements and extending component life
- Improved sustainability: Contributes to green building certifications such as LEED and BREEAM
For low standby power DIN PSU applications in building automation, the TPS060-GP24V’s <0.3W no-load consumption sets a benchmark for energy efficiency in the 60W power class.
4. Ultra-Compact Design: Maximizing DIN Rail Space
Modern building automation control cabinets are shrinking. As building systems become more sophisticated, the number of controllers, gateways, and I/O modules increases—but the available cabinet space often does not. Every millimeter of DIN rail space is valuable real estate.
The TPS060-GP24V measures just 91×71×60mm, making it one of the most compact 60W DIN rail power supplies in its class. This ultra-slim profile frees up valuable rail space for additional controllers, I/O modules, or safety relays. A narrower profile also improves overall airflow within the control cabinet, enhancing natural convection cooling and extending the lifespan of all components.
For ultra-slim DIN rail PSU applications, the TPS060-GP24V supports both TS35/7.5 and TS35/15 DIN rails, providing flexibility for different cabinet configurations. The lightweight design (approximately 255g) simplifies installation and reduces mechanical stress on the DIN rail.
The compact housing features a flame-retardant PC casing rated UL94V-0, ensuring safety even in the event of internal faults. IP20 double insulation provides protection against contact with live parts while allowing convection cooling for silent operation.
5. Safety and Compliance: Global Certifications for Building Automation
Building automation equipment must meet rigorous safety and compliance standards to ensure safe operation and regulatory acceptance. The TPS060-GP24V carries a comprehensive suite of certifications that make it suitable for building automation applications worldwide:
- CE marking: Compliance with Low Voltage Directive 2014/35/EU and EMC Directive 2014/30/EU
