CZCHENGLIAN CL-A1-300-5: 5V Power for LED Screens
The CZCHENGLIAN CL-A1-300-5 is an AC-to-DC switching power supply for compatible 5V LED display modules. It provides a 5V DC output, a 60A rated output current and a maximum output power of 300W. The metal housing measures 215 × 115 × 50 mm and uses a DC fan for cooling.
For a replacement or a new LED cabinet, match the module voltage, total load, cabinet space and AC supply before ordering. The CL-A1-300-5 is the 5V model; a similar model name or housing alone does not establish compatibility.

Switchable AC Input
The specified input ranges are 100–125V AC or 180–264V AC. This is a switchable input design, so the range setting must match the local mains supply before power is applied. Do not treat these two ranges as one continuous automatic input range.
Protection and Cooling
- Overcurrent protection: the listed protection threshold is 75–85A. This threshold is not the rated operating current; size the load around the 60A rating and the applicable operating conditions.
- Overtemperature protection: the listed threshold is 68–78°C, with automatic recovery after the temperature falls.
- Short-circuit protection: the listed behavior is lockout with recovery after restart. Correct the fault before restarting.
- Fan cooling: allow space for ventilation when positioning the supply inside an LED cabinet.
How to Check Replacement Compatibility
- Confirm 5V output: compare the old supply label with the voltage required by the LED modules.
- Calculate the load: add the maximum current or power of all connected modules. For this model, 5V × 60A equals 300W. Allow suitable operating headroom for the cabinet conditions.
- Check the installation: compare the 215 × 115 × 50 mm housing, mounting points, terminal layout and cable space with the existing cabinet.
- Check the input range: match the AC selector to the supply voltage before energizing the unit.
The number of modules one supply can power depends on each module’s maximum consumption and the cabinet design. A fixed module count cannot be determined from the power-supply model alone. Installation should follow the unit’s terminal markings and the cabinet’s electrical requirements.

Frequently Asked Questions
What are the output voltage and power of the CL-A1-300-5?
The CL-A1-300-5 is specified for 5V DC output, 60A rated output current and 300W maximum output power.
Can it be used with 110V and 220V AC supplies?
Yes, when the mains voltage is within the corresponding 100–125V AC or 180–264V AC range and the input selector is set correctly before power is applied.
Can it replace any 5V 300W LED power supply?
Voltage and power are only part of the check. Also compare input range, dimensions, mounting, terminal layout, cooling and the connected load before choosing a replacement.
Does this model use a cooling fan?
Yes. The listed cooling method is DC fan ventilation, and the housing dimensions are 215 × 115 × 50 mm.
