📊 Selection Tips
When selecting a Weidmüller power supply:
Total current load → Add up the current of all devices.
Buffer or redundancy needed?
Environmental conditions → Check temperature, dust, vibration.
Communication required? → Go with PROtop for smart connectivity.
Panel space → Choose compact models if space is tight.
