What types of power supplies are used in industrial environments?
Industrial applications place special demands on power supplies: temperature tolerance, shock resistance, EMC stability, and long service life are crucial.
Typical variants:
- 24V power supply: Industry standard for control technology, PLC, and automation
- 12V power supply: Used in embedded systems, surveillance solutions, and small control devices
- ATX power supply / SFX power supply: For industrial PCs and servers, tailored to housing formats
- 500–1500 watt power supplies: Powerful variants for servers and workstations with high loads
Pay attention to protective functions such as surge protection, short-circuit resistance, and redundant design for applications where interruptions are critical.
Power supplies for industrial PCs & servers – what power is required?
The power class depends on the energy requirements of the installed components:
- 500-watt power supply to 600-watt power supply: For simple industrial PCs and control units
- 650-watt power supply to 850-watt power supply: Standard for industrial workstations or servers with multiple drives
- 1000 watt power supply to 1500 watt power supply: For high-performance systems, GPU servers, or redundant power supplies
- Dell power supply / Cisco power supply / IBM power supply: OEM-compatible models for specific server platforms
A 750 watt power supply is often the best choice for scalable systems with performance reserves.
