Ensure the instrument is operated within a temperature range of 0 to 40°C. Second, the vent could be blocked. Make sure to clear the vent to allow for proper ventilation.
What to do if Chroma Power Supply shows Over Current Protection (OCP)?
If the Chroma Power Supply shows an Over Current Protection (OCP) fault, it means the output current exceeds the specified limits or the OCP settings. To resolve this, remove the overload connected to the power supply or increase the OCP settings.
What to do if Chroma Power Supply shows Over Power Protection (OPP)?
If the Chroma Power Supply displays an Over Power Protection (OPP) error, it indicates that the output power is exceeding the specified limits or the OPP settings. To fix this, remove the overload or increase the OPP settings.
What does Input Error Protection 1 AC FAULT mean for Chroma Power Supply?
If you encounter an Input Error Protection 1 AC FAULT on your Chroma Power Supply, it means that the voltage of the AC input line is either too low or too high. To solve this, measure the input voltage and adjust it if it exceeds the specified limits.
What to do if Chroma Power Supply shows Over Voltage Protection (OVP)?
If the Chroma Power Supply shows an Over Voltage Protection (OVP) fault, it means the output voltage exceeds the specified limits or the OVP settings. Check the OVP settings. If the protection state cannot be reset, contact your local sales agent for further assistance.
What does D/D FAULT mean on Chroma A620028?
If the Chroma Power Supply displays a D/D FAULT error, it could be due to a large transient current or damage to the D/D power stage. If a D/D FAULT protection occurs, first turn off the power supply and remove the load. Ensure that the cables are connected correctly, and then power it on again. If the issue persists, contact your local sales agent for further assistance.
Why does my Chroma A620028 show 'ERROR!!! MASTER OR SLAVE NO MATCH'?
If your Chroma Power Supply shows 'MATCH warning that the models are incompatible when connected in series or parallel (ERROR!!! MASTER OR SLAVE NO MATCH)', this means the model numbers do not match. Different model power supplies cannot be connected in series or parallel mode. If you need further assistance, contact your local sales agent.
Why does my Chroma A620028 have no output voltage?
If the Chroma Power Supply is not providing any output voltage, it could be due to abnormal output voltage feedback or damage to the D/D power stage. If the protection state cannot be reset, contact your local sales agent.
How to fix Chroma DC Power Supply control issues via GPIB?
If you are unable to control the Chroma DC Power Supply via GPIB, it could be due to an incorrect address or a loose/disconnected GPIB cable. Update the address and check the cable connection, securing it with screws.
What does 'Current sharing cable connection error (C/S CABLE ERR.)' mean on Chroma A620028 Power Supply?
If the Chroma Power Supply displays 'Current sharing cable connection error (C/S CABLE ERR.)', it means the current sharing cable is connected when used in series mode. Check if the cables are connected correctly. Contact your local sales agent for further assistance.
