  If the Chroma AC Power Distribution unit is showing an OVER TEMP protection (OTP) message, it means that either the ambient temperature is too high, or the airway is obstructed. To solve this: 1. Ensure the unit is operated within a 0 ~ 40°C environment. 2. Check and clear any obstructions in the airway.

Why is the output distorted on my Chroma 61503?
- M
  millsleslieSep 2, 2025
  If the Chroma AC Power Distribution unit displays distorted output, it could be due to two reasons: 1. The AC source output voltage is too low; in this case, program a higher output voltage. 2. The rectified load is too large at high frequency; in this case, reduce the load or lower the output frequency.

What to do if Chroma 61503 shows INT _ AD protection?
- C
  Christopher RobinsonSep 5, 2025
  If the Chroma AC Power Distribution unit displays an INT _ AD protection message, this could be due to a line input voltage cycle dropout, an instant over current of output, or a damaged AD power stage. To address this: 1. Check the stability of the input voltage. 2. Remove the load. 3. If the protection status cannot be reset, consult the dealer for assistance.
