FAQs
What is the primary function of the 85165 power supply?
It converts AC grid voltage into a regulated 24V DC output for industrial automation components.
Can I use this power supply in an outdoor application?
No, the unit has an IP20 rating and must be installed inside a clean, dry, and protected enclosure.
Is the output voltage fixed at 24V?
While set to 24V nominal, it is adjustable between 22.5V and 28V via the integrated controls.
What happens if the output is short-circuited?
The device includes built-in short-circuit protection designed to prevent damage during a fault event.
How is the unit mounted?
The unit is designed for standard rail mounting commonly found in industrial control cabinets.
What is the maximum current output?
The unit provides a maximum of 10A output current.
Troubleshooting
No output voltage at the DC terminals
Verify input AC power supply is active and within the 100-265V range. Check that the fuse or circuit breaker upstream is not tripped.
Output voltage is below 24V
Check if the unit is overloaded. If current demand exceeds 10A, the unit may enter a protection mode. Adjust the output voltage setting if necessary.
The unit is running excessively hot
Ensure there is at least 50mm of clearance above and below the unit for ventilation and verify the ambient temperature is within the rated operating range.
Pros and Cons
Pros
- Wide input voltage compatibility simplifies global sourcing
- Adjustable voltage range allows for precise tuning
- Compact dimensions maximize control cabinet space
- Robust build quality designed for industrial longevity
- Simple DIN-rail mounting for quick installation
Cons
- IP20 rating limits use to clean, dry environments only
- Requires professional installation due to direct AC wiring
- No built-in visual display for real-time monitoring
Setup, Compatibility & Care
Installation should always be performed by a qualified technician according to local electrical codes. The unit is designed for standard DIN-rail mounting inside a control cabinet. Ensure adequate airflow around the unit to prevent thermal throttling, as the compact design generates heat under full load. Connections are made via the integrated screw terminals; ensure wires are stripped correctly and tightened to the manufacturer's torque specifications to prevent loose contacts. Regular maintenance includes checking for dust accumulation on the casing and verifying that terminal connections remain secure after vibration or thermal cycling.
