When is a PSU the right choice?
A Power supply unit are the right choice when electronic components need stable and continuous power supply in industrial environments.
- Cabinets and enclosures with PLC, relays and I/O
- Automation systems requiring stable DC voltage
- Installations with continuous operation
- Environments where voltage fluctuations can cause operational problems
A properly sized power supply contributes to high operational reliability and a long service life of the system.
When might other solutions be more appropriate?
- Requirements for operation during power outages → UPS
- Temporary or mobile power supply → adapters / lab units
- Redundancy or monitoring requirements → UPS / monitoring solutions
How are PSUs used in cabinets?
PSUs are typically mounted on DIN rails in electrical cabinets and are used to power multiple components from a common power source.
Common uses:
- PLC and control systems
- Relays and contactors
- Sensors and actuators
- Communication and I/O modules
Technical characteristics of PSUs
- Stable DC output (typically 24 V)
- Adapted for DIN rail mounting
- Protection against overload, short circuit and overvoltage
- Intended for continuous industrial operation
- Compact formats for installation in control cabinets
