A-200AF-4.5 low-profile 4.5 V LED supply
The CZCL A-200AF-4.5 is the 180 W, 4.5 V version of the A-200AF series. Its fanless design and 30 mm enclosure height suit compatible LED cabinet layouts, with short-circuit and overload protection.
Use the exact model column when selecting the supply: the series includes different output voltages and power ratings. Full-load operation requires the specified aluminum heat-sink plate, and the temperature derating curve remains applicable.

Frequently asked questions
Is the A-200AF-4.5 rated at 200 W?
The exact 4.5 V model column lists 40 A and 180 W. The 200 W figure belongs to the 5 V model in the series; it should not be applied to the 4.5 V variant.
Can this supply replace a 5 V model?
The nominal output is 4.5 V with a documented ±3% adjustment range. Match the LED module’s voltage requirement and the complete electrical and mechanical specification before considering a replacement.
What AC input is supported?
The specified range is 180–264 V AC at 47–63 Hz. The document does not list 110 V AC operation for this series.
Does the fanless supply need an aluminum plate?
Yes. The manual requires a 400 × 400 × 3 mm aluminum plate for full-load operation. Follow the derating curve as cabinet temperature rises.
How does it recover from overload or a short circuit?
Overload protection is specified at 110–150% of rated load in hiccup mode, with recovery after the fault is removed. Short-circuit protection also recovers automatically after the short is cleared.
