DC-DC power supply for vehicle LED screens
The LAVALEE ASD-12D5N60A300DT converts a DC vehicle power source into 5V power for an LED display. The product label identifies it as a non-isolated DC-DC converter, with a DC 10–32V input, a 5V/60A display output and a dedicated 5V/3A output for a control card. This separates the two labeled connection groups and helps buyers identify the correct replacement.

The electrical values and terminal markings above can be checked against the original product photographs below. The 300W figure describes the 5V/60A display output; it is not a statement of combined output capacity or continuous capacity under every temperature condition.
Protection and cooling features
- Input reverse-polarity protection.
- Output over-current, over-voltage, under-voltage and short-circuit protection.
- Two-stage output over-voltage protection.
- Low output ripple and noise, as described in the product listing.
- Temperature-controlled fan and ventilated aluminum alloy housing.
Replacement and wiring checks
Before replacing an existing vehicle LED power supply, compare its full model number, input range, output ratings, terminal layout and mounting space with this unit. A matching 5V output alone does not establish interchangeability. Check the display and control-card power requirements separately, including the high-temperature power reserve shown on the housing.
The photographs show the input and output labels, including the ACC (ON/OFF) terminal. They are a terminal reference, not a complete vehicle wiring diagram. Confirm the ACC control requirements and installation-specific wiring before connection; do not assume its operating voltage or bridge terminals based only on the photograph.
For replacement assistance or purchasing questions, contact our team with the existing unit’s label photo, vehicle supply voltage, LED display load and installation details.
Frequently asked questions
Does this power supply use AC mains or DC input?
It is labeled as a non-isolated DC-DC converter with DC 10–32V input. It is not an AC mains input power supply.
What is the difference between the two output groups?
The housing labels one output DC 5V/3A for a control card and the other DC 5V/60A for the display. Match each load to the correct labeled terminal group.
Can the display use the full 300W in a hot vehicle?
Do not size a hot vehicle installation solely from the 5V × 60A rating. The housing explicitly instructs users to reserve 50% power capacity because of high vehicle temperatures. Confirm the suitable load for the actual installation.
Is a wiring diagram available on this page?
The original photos show terminal positions and markings. This page does not include a complete wiring diagram or ACC control specification. Contact our team to confirm those details for your installation.
How do I check whether this is the right replacement?
Compare the complete ASD-12D5N60A300DT model, input range, both output ratings, terminal arrangement and physical fit. Send a label photo and your load requirements through our contact page if you need help confirming the match.
