Automation meets energy efficiency: Why power supply matters
Automation solutions are now present in almost every aspect of our lives – from intelligent production lines to autonomous delivery vehicles and robots that move goods in warehouses. With the rapid advancement of artificial intelligence (AI) and robotics, our technological landscape is changing fundamentally.
Machines like collaborative robots (cobots), humanoid robots, autonomous mobile robots (AMRs), and automated guided vehicles (AGVs) are becoming more powerful and versatile. However, without a reliable power supply, these high-tech assistants would not be able to function. Especially in battery-powered systems, DC/DC converters play a key role in providing stable and efficient energy to various components.
Battery-powered robotics: The power supply challenge
Modern mobile robots and automation systems rely on battery packs to operate flexibly and autonomously. Whether a cobot on the assembly line or an AGV working in shifts – all depend on powerful battery systems.
However, batteries do not provide constant voltage levels. This is where DC/DC converters come into play. They reliably convert, for example, a 48 V battery voltage into 24 V or 12 V for motor controllers, sensors, or control electronics. To ensure robots work efficiently, converters must be compact, robust, and highly efficient.
Ultra-wide input voltage range: Flexible from 28 V to 160 V
An ultra-wide input voltage range is essential:
- 24 V batteries typically range between approx. 20 V and 28 V
- 48 V systems fluctuate between approx. 40 V and 58 V
- 96 V batteries can reach up to approx. 112 V
- Voltage spikes caused by recuperation are common
Our DC/DC converter 154DH-24-ON, with an input range from 28 V to 160 V, covers all these scenarios – stably, safely, and without power loss.
Common battery voltages in robotics: 24V, 48V, 96V
- 24 V: Ideal for small robots, cobots, or AGVs – safe and compact.
- 48 V: The standard for AMRs and AGVs. Higher power output with manageable safety measures.
- 96 V: For high-performance systems with heavy drive demands – such as humanoid robots or modular platforms.
Our DC/DC converters cover all these ranges – often one module is sufficient for multiple platforms.
Compact design – made for tight installation spaces
Every millimeter counts in robotics. Our converters are particularly compact, allowing you to place them directly in joints or within a chassis – resulting in shorter wiring and greater precision.
Our DC/DC converter 145-24-SD, with a maximum input voltage of 100 V and compact dimensions of 77×52×19 mm (fully encapsulated in an aluminum case), is ideal for the smallest installation spaces.
High efficiency = longer runtime, less hea
A 95% efficiency means only 5% of the energy is lost as heat. This brings several advantages:
- Longer battery life
- Often no external heat sink required. While the DC/DC converter is in operation, heat is lost, which is emitted directly into the environment via the metal housing
- Increased electronic lifespan
Our converters are designed for efficiency and durability – even in continuous operation.
No derating – full power even in high temperatures
Many converters reduce their output under high temperatures. Ours don't. They deliver full rated power even at ambient temperatures from -40°C to +85°C - without derating.
This saves space, simplifies cooling, and makes your design more reliable.
Real-world examples: How our converters power cobots and AGVs
🔧 Example 1: Cobot with a 48V battery
A cobot is powered by a 48V battery pack. Our DC/DC converter flexibly converts this into 24V or 12V – whether the battery voltage is 58V or 40V. The compact design allows direct installation into the joint, close to the motors – shorter cable paths, higher precision.
🚛 Example 2: AGV in intralogistics
An AGV with a 24V or 48V battery supplies laser scanners, controllers, and grippers via a DC/DC converter. Our robust, vibration-resistant converters are built for continuous operation. Thanks to the ultra-wide input range, the same converter remains usable even when switching to 60V or 96V systems. Plus, the high efficiency ensures your robot can run longer before needing the next charge.
