200W Dual-Output Power for LED Screens
The LaitePower T200V3.8-2.8A1 combines active power factor correction (PFC) with two DC outputs in a slim enclosure. It is designed for LED displays that require separate +3.8V and +2.8V supplies. Check the channel assignment and load conditions before replacing an existing power module.

Cabinet and Replacement Checks
Compare the complete model number, both output voltages and the connector labels with the original unit. Check mounting-hole locations and cable clearance in addition to the enclosure dimensions. The 200W figure is the specified power for the supply, not a separate 200W rating for each output.
Refer to the PDF for derating curves and installation conditions. The listed cold-start temperature does not replace the continuous operating-temperature range.

Frequently Asked Questions
Does the T200V3.8-2.8A1 support 110V and 230V AC input?
Both are within the specified 90–264Vac input range. The rated input range is 100–240Vac; consult the PDF for load and derating conditions.
Which terminals supply 3.8V and 2.8V?
The +3.8V output is assigned to CON5/6 (+)(−), and the +2.8V output to CON2 (+)(−). Verify the markings on the unit before connecting the display.
Is the 200W rating available on each output?
No. 200W is the specified output power of the power supply. Each output has its own 0–30A range at 100–240Vac input.
Does this power supply include active PFC?
Yes. The model description specifies active PFC. The listed power factors are at least 0.99 at 100Vac and at least 0.96 at 230Vac.
How thick is the T200V3.8-2.8A1?
Its listed overall dimensions are 210.0 × 58.0 × 26.0mm (±0.5mm). Check the installation drawing in the PDF for mounting details.
