Frequently Asked Questions - RPT-75D Mean Well
What is the input voltage range for the Mean Well RPT-75D?
The input voltage range is 85-264 VAC (universal AC input), covering 100-240 VAC nominal.
What are the output specifications of the RPT-75D?
The RPT-75D provides dual outputs: +5V at 6A and +24V at 2.5A, with a total power of 75W.
How do I connect the AC input to the power supply?
Connect the AC line (L) and neutral (N) to the corresponding screw terminals. Ensure the ground wire is connected to the FG terminal for safety.
Can the RPT-75D be used in parallel or series?
Parallel operation is not recommended. Series operation is possible for higher voltage, but ensure each output is adjusted properly and diodes are used if needed.
What protections does the RPT-75D have?
It includes short circuit (hiccup mode), overload (approximately 105-150% rated output power), and overvoltage protection.
How should I mount the power supply?
Mount it in a well-ventilated area. Use the mounting holes on the casing. Avoid blocking airflow for proper convection cooling.
What is the operating temperature range?
It operates from -20°C to +70°C, but output power derates linearly above 50°C to about 50% at 70°C.
How do I adjust the output voltage?
Each output has a trim pot (V.ADJ) for fine-tuning. Use a small screwdriver to adjust within the specified range (e.g., ±10% for each output).
What should I do if the power supply does not power on?
Check the AC input voltage and fuse. Ensure all connections are secure. If the green LED is off, verify that the input power is present and the load is not shorted.
Is the RPT-75D compliant with safety standards?
Yes, it is certified to UL 60950-1 and EN 60950-1, and carries the CE mark.
