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
