4.2V 300W LED Power Supply (71A)
4.2V 300W 71A LED power supply for common-cathode indoor modules. 87–88% efficiency, adjustable 4.0–4.4V, low ripple for fine pitch.
The 4.2V rail is standard for common-cathode indoor modules — including most P2.5 indoor product, which is rated 4.2V rather than 5V. Fine-pitch cabinets cannot afford a cheap supply here: ripple shows as a faint horizontal band on grey.
Ripple on this unit is specified at 120 mV, low for the price class. Measure a sample before committing to a large order.
- 4.2V, 71A, 300W

Questions on this line
Does ripple matter?
At P1.86 and below, yes. A 300 mV supply shows a band that no calibration removes.
Will a 5V supply work?
For a week. Then the driver IC fails. Match the module rating.
