CZCHENGLIAN CL-A2-400-5 5V LED Display Power Supply
The CZCHENGLIAN CL-A2-400-5 is an AC-to-DC switching power supply for LED video walls and display cabinets using compatible 5V modules. When replacing an existing supply, match the complete model number, electrical ratings, terminal layout and mounting dimensions to the unit being removed.
Its metal enclosure and fan cooling suit cabinet integration where airflow and service access are available. A matching output voltage is only the first selection step: the connected modules’ total current demand and the cabinet’s operating conditions also determine whether a power supply is suitable.
Specifications and Compatibility
The following reference details are taken from this product listing. Confirm the supplied unit’s label and applicable specification before finalizing an installation or replacement.
| Item | Reference detail | What to check |
|---|---|---|
| Brand and model | CZCHENGLIAN / Chenglian CL-A2-400-5 | Match the full model and any revision suffix. |
| DC output voltage | 5V | Use only with modules specified for this voltage. |
| Rated output current and power | Confirm the supplied unit’s nameplate | See the rating clarification below before calculating the load. |
| AC input | 190–264V AC listed; 47–63Hz | Verify the actual label; 110V operation is not established by this listing. |
| Enclosure dimensions | 202 × 114 × 49.5 mm (L × W × H) | The earlier listing also gives a 199 mm length in parentheses; check mounting centers separately. |
| Cooling | DC fan ventilation; dual fans listed | Allow clearance around ventilation openings. |
Output Rating Clarification
The earlier description for this CL-A2-400-5 listing stated 60A and 300W. Those figures have not been confirmed for the supplied model, so they should not be used as a verified load rating. The model number alone is also insufficient to establish a 400W rating. Before ordering, contact us to confirm the unit’s nameplate and specification, especially for a replacement in an existing cabinet.
Choosing a Power Supply for Your LED Cabinet
- Match the module voltage: confirm that every connected load is designed for 5V DC.
- Calculate the maximum load: add the modules’ specified maximum current demand, then account for the power supply’s confirmed rating and temperature derating. Do not size the supply from average video playback consumption alone.
- Check the mechanical fit: compare mounting holes, terminal positions, enclosure clearance and cable access with the existing supply.
- Check the AC source: use the input range marked on the supplied unit. The legacy reference to current at 110V does not establish 110V compatibility.
- Confirm the installation environment: arrange suitable cabinet ventilation and environmental protection. This listing does not establish a waterproof or outdoor exposure rating.
For replacement matching, provide the existing unit’s label, cabinet layout and LED module specifications. Browse our LED power supplies or Chenglian product range to compare available options.
Frequently Asked Questions
What is the CL-A2-400-5 used for?
It supplies 5V DC power to compatible LED display modules in video wall cabinets. It is a power supply, so a separate LED control system is required to manage display content.
Is the CL-A2-400-5 rated at 300W or 400W?
The old listing stated 60A / 300W, but that rating has not been verified for the supplied unit. Confirm the nameplate and matching specification before purchasing or sizing the load; do not infer the rating from the model name.
Can this power supply run on 110V AC?
110V operation is not confirmed. The input range recorded in this listing is 190–264V AC. Check the actual input label before connecting power.
How many LED modules can one supply power?
There is no fixed module count. It depends on each module’s maximum current demand, the unit’s confirmed output rating, operating temperature and the required design margin. Obtain these values before selecting the quantity of power supplies.
Can it replace another 5V LED power supply?
Only after checking current capacity, AC input compatibility, mounting dimensions, terminal layout and cooling requirements. A 5V label by itself does not establish interchangeability.
Conclusion
The CZCHENGLIAN CL-A2-400-5 is a 5V LED display power supply option for compatible video wall cabinets. For a suitable replacement, confirm the supplied unit’s electrical ratings and mechanical fit alongside the LED modules’ requirements before placing an order.
