What to do if Chroma 61603 shows OVER CURRENT protection (OCP)?
If the Chroma Power Supply indicates an OVER CURRENT protection (OCP) fault, it means the output current exceeds the specified limit or the set I LIMIT. To resolve this, remove the overload connected to the power supply or increase the I LIMIT setting.
What to do if Chroma 61603 shows OVER POWER protection (OPP)?
If your Chroma Power Supply displays an OVER POWER protection (OPP) message, it signifies that the output power is beyond its specification. To fix this, either decrease the output voltage or remove the excessive power draw from the connected load.
What to do if Chroma Power Supply shows OUTPUT SHORT protection?
If the Chroma Power Supply shows an OUTPUT SHORT protection error, it indicates a short circuit at the output or a reverse current flow. To resolve this: 1. Remove the short circuit. 2. Disconnect the load.
What to do if Chroma 61603 Power Supply shows OVER TEMP protection (OTP)?
If the Chroma Power Supply displays an OVER TEMP protection (OTP) warning, it means the unit is overheating. This could be due to: 1. High ambient temperature: Ensure the unit is operated within a 0 ~ 40°C environment. 2. Obstructed airflow: Clear any blockages from the air vents to allow proper ventilation.
What to do if Chroma Power Supply shows INPUT FAIL protection (UVP)?
If the Chroma Power Supply shows an INPUT FAIL protection (UVP) message, it means the AC source line input voltage is either too low or too high. You should measure the input voltage and adjust it if it's outside the specified range.
Why is Chroma 61603 output distorted?
The distorted output from the Chroma Power Supply can be caused by: 1. AC source voltage being too low: Try programming a higher output voltage. 2. Rectified load being too large at high frequency: Reduce the load or lower the output frequency.
What to do if Chroma Power Supply shows OUTPUT OVP protection?
If the Chroma Power Supply displays an OUTPUT OVP protection message, it could be due to: 1. Remote sense being open: Connect the output to the remote sense terminals. 2. Output voltage peak exceeding the range: Check the settings of Vac and Vdc on the MAIN PAGE.
What to do if Chroma Power Supply shows INT _ AD protection?
If the Chroma Power Supply shows an INT _ AD protection message, it may be due to: 1. Line input voltage cycle dropout: Check the stability of the input voltage. 2. Instant over current of output: Remove the load. If the protection status persists, it may indicate damage to the AD power stage, and you should consult the dealer for assistance.
What to do if Chroma Power Supply shows INT _ DD protection?
If the Chroma Power Supply shows an INT _ DD protection message, it may be due to: 1. Line input voltage cycle dropout: Check the stability of the input voltage. 2. Instant over current of output: Remove the load. If the protection status persists, it may indicate damage to the DD power stage, and you should consult the dealer for assistance.
How to fix poor measurement of V, I on Chroma 61603?
Poor voltage and current measurements on the Chroma Power Supply can be caused by the aging of internal components, leading to deviations in their characteristics. Periodic calibration is required to maintain accuracy.
