Troubleshooting
No output voltage
Verify the 24 VDC input voltage is present and correct. Check all input and output connections for proper seating.
Output voltage is unstable
Ensure the input voltage is stable. Check if the connected load exceeds the 500 mA maximum output current. Inspect for loose connections.
Converter overheats
Ensure proper ventilation around the unit. Reduce the load if it is consistently near the 500 mA limit. Verify input voltage is within specification.
Converter fails to power on
Confirm the 24 VDC input power source is functioning correctly. Check the polarity of the input connections.
