Why Does an AGV/AMR With a 24V Battery Still Need Isolated 12V and 24V Auxiliary Power?
At first, the architecture looks simple.
The AGV already has a 24V battery. Why not power 24V devices directly and add a small converter for the 12V loads?
The real engineering question is different:
What happens to sensitive electronics when motors, drives and other high-power loads continuously change the electrical conditions of the shared DC bus?
An AGV/AMR typically combines:
Power + Motion + Control + Communication + Sensing
inside one compact platform.
Poor power architecture may result in controller resets, communication dropouts, sensor abnormalities and intermittent I/O faults.
What appears to be a software or network problem can actually originate from the power path.
Why Is Multi-Voltage AGV/AMR Power More Complicated Than Simple Step-Down Conversion?
1. One machine may require both 12V and 24V loads
12V may be required by IPCs, gateways, cameras or auxiliary electronics.
24V may supply controllers, remote I/O, sensors and industrial communication equipment.
Using separate converters increases module count, wiring, connectors, mounting requirements and potential failure points.
A dual-output converter can simplify this architecture.
2. A 24V battery bus is not always exactly 24V
Battery SOC, motor operation and changing loads affect the electrical conditions of the DC bus.
Sensitive electronics therefore need more than nominal voltage compatibility.
They need a stable auxiliary power path under changing operating conditions.
3. Motors and sensitive electronics share a compact platform
Motor drives and switching loads can create a challenging EMI environment.
At the same time, controllers, communication devices and sensors are sensitive electronic loads.
Galvanic isolation helps create an electrical boundary between the upstream power domain and downstream auxiliary electronics.
4. Space inside an AGV/AMR is limited
Adding separate converters for every voltage rail increases wiring, mounting and thermal complexity.
A dual-output architecture can serve two auxiliary voltage domains from one conversion stage.
How Does MDB175-24D12&24 Solve the Problem?
A practical auxiliary power architecture can be created:
24V Battery / DC Bus
↓
MDB175-24D12&24 Isolated DC-DC Converter
↓
12VDC + 24VDC Auxiliary Power
↓
IPC / Gateway / Communication + PLC / I/O / Sensors
The 12V output can support IPCs, gateways, cameras and auxiliary electronics.
The 24V output can support controllers, remote I/O, sensors and industrial electronics.
The engineering value is therefore not simply:
24V → 12V + 24V
It is a more organized multi-voltage auxiliary power architecture.
