What to do if Chroma Power Supply shows Over Temperature Protection (OTP)?
If your Chroma Power Supply displays an Over Temperature Protection (OTP) error, it could be due to two reasons: either the ambient temperature is too high, or the vent is blocked. To resolve this, first, ensure that you operate the instrument within a temperature range of 0 to 40°C. Second, check the vent and clear any blockage.
What to do if Chroma Power Supply shows Over Current Protection (OCP)?
If your Chroma Power Supply is showing an Over Current Protection (OCP) error, it means the output current exceeds the specified limit or the OCP settings. The solution is to remove the overload or increase the OCP settings.
What to do if Chroma Power Supply shows Over Power Protection (OPP)?
If the Chroma Power Supply indicates Over Power Protection (OPP), it means that the output power is exceeding the specified limits. To fix this, remove the overload or increase the OPP settings.
What to do if Chroma Power Supply shows Over Voltage Protection (OVP)?
If your Chroma Power Supply displays an Over Voltage Protection (OVP) error, it indicates that the output voltage exceeds the specified limits or the OVP settings. First, check the OVP settings. If the issue persists, consult with your local sales agent.
Why is my Chroma Power Supply showing Input Error Protection 1 AC FAULT?
The Chroma Power Supply shows 'Input Error Protection 1 AC FAULT' because the voltage of the AC input line is either too low or too high. To resolve this, measure the input voltage and adjust it if it exceeds the specified limits.
How to fix D/D power stage error protection (D/D FAULT) on Chroma Power Supply?
If the D/D FAULT protection is triggered on your Chroma Power Supply, it could be due to a transient current that is too big or the D/D power stage being damaged. When this occurs, first turn off the power supply and remove the load. Make sure the cables are connected correctly, then power it on again.
What to do if Chroma Power Supply has no output voltage?
If your Chroma Power Supply has no output voltage, it could be due to the output voltage feedback being abnormal or the D/D power stage being damaged. Consult with your local sales agent if it is unable to reset the protection state.
How to fix Fan Fail Protection (FAN LOCK) on Chroma Power Supply?
If your Chroma Power Supply displays 'Fan Fail Protection (FAN LOCK)', it means that the fan is out of order or the feedback circuit is abnormal. Consult with your local sales agent if it is unable to reset the protection state.
Why is Chroma Power Supply output not within Accuracy SPEC?
The Chroma Power Supply output may not be within the accuracy specification due to feature swings caused by aged components. It requires periodic calibration. See section 3.2.4.4 Calibration.
Why does Chroma Power Supply have bad measurement for V, I?
The Chroma Power Supply might show bad measurements for Voltage (V) and Current (I) because of feature swings due to aged components. It needs calibration periodically. See section 3.2.4.4 Calibration.
