250W 12V power supplies with three output leads
Choose the 12V supply around the complete lighting load and cable plan. The SL-HT-250-12 catalogue reference covers a 250W power unit labelled for 12V DC output at 20.8A. Its original picture shows three two-conductor output leads, a separate input lead, a black enclosed case and an IP67 marking.
For sign manufacturers, illuminated-display fabricators and wholesale lighting buyers, the pictured lead arrangement makes branch selection part of the order specification. Provide the lighting models, combined load and connection drawing to agree the permitted lead ratings and a suitable sample assembly.

Three output leads and total-load selection
The photograph shows three two-conductor output cables beside a separate input cable. Define the connected lighting branches and their required terminations in the approved assembly drawing.
The 250W and 20.8A ratings describe the complete unit. Provide the combined lighting load and proposed branch loads to confirm the permitted operating configuration and cable ratings. Request the technical data applicable to the quoted version with the sample selection.
Input, mounting and IP67-marked configuration
Provide the local mains voltage and installation environment with the enquiry to confirm the required input range and installation data for the selected version. Request complete enclosure dimensions and cable lengths to check the mounting positions and wiring space.
The original label shows IP67. Agree the connection-protection arrangement and request current model-specific documents for the destination market when approving the sample and production specification.
Bulk 12V supply and cable customisation
Wholesale orders start at 20 pcs, with volume pricing for larger quantities. Samples are available; charges and destination shipping are confirmed separately. Standard lead time is 12–18 days.
OEM, ODM and private-label requirements can include output-lead lengths, terminations, marking and packing specifications. Include the assembly drawing and target quantity to confirm the custom scope and quotation. Custom schedules and transit are agreed separately.
Three-lead 12V power supply purchasing questions
What output current appears on the 250W label?
The original label specifies 12V DC at 20.8A. Use this value with the total connected lighting load when assessing SL-HT-250-12 for the project.
Does each of the three leads provide 250W or 20.8A?
The label ratings apply to the complete power unit. Confirm the combined load and the permitted current for each cable branch in the approved configuration.
What information defines the three-lead assembly order?
Provide a drawing with the lighting branches, loads, lead lengths, termination types and mating connectors. Include the local mains voltage, mounting layout, quantity and destination to confirm the sample.
Which documents should I request for the IP67-marked supply?
Identify the installation environment and destination-market requirements. Obtain current technical data, input specification and installation requirements applicable to the quoted version.
