TMT DC 12V Output Class 2 Power Supplies (LDM…P-12 series)

Power suppliesCurrentLast verified 6 sourcesAlso listed as: DC 12V Output Class 2 Power Supplies, LDM120P-12-C22, LDM180P-12-C23, LDM240P-12-C24, LDM300P-12-C25, L2-120N series, L2-300N series

usa.tmtleds.com lists five 12V DC Class 2 constant-voltage LED power supplies from 60W (1 output) to 300W (5 outputs). The linked datasheets (120W–300W) state 5A per output group, 100-277Vac input (120-277Vac for 300W), UL8750, IP67/IP68 and a 5-year warranty (Tc 75℃).

Sources disagree on 3 values. Values are shown per revision below rather than merged. See details.

Revisions & regional differences

TMT publishes product information on several regional websites and in datasheets. Where they differ, each description is kept as its own revision instead of choosing one value.

RevisionRegionPeriodNotes
USA listing (usa.tmtleds.com) and linked datasheetsUSAseen 2026-09SKU rows keyed by LDM product code come from the web page; rows keyed by the internal model (L2-…N-012-…) come from the datasheet 'Model' row. The 60W LDM060-12-C21 has no datasheet link on the page.

AC input: 120W/180W/240W datasheets state 100-277Vac input; the 300W datasheet states 120-277Vac.

Possible explanation (not confirmed by a source): This may reflect a per-model input rating rather than a series-wide value.

Operating temperature: Working temperature is -40~+60℃ on the 120W/180W datasheets, -40~+50℃ on 240W and -40~+45℃ on 300W.

Possible explanation (not confirmed by a source): This may reflect thermal derating of higher-wattage models.

IP rating: Datasheet features list 'IP67/IP68' while the mark row on the same page shows 'IP67'.

Open questions

No datasheet is linked for LDM060-12-C21 (60W, TMT-105675); its only data is the web listing. The US power-supplies page states no warranty; warranty comes from the datasheets. The usa.tmtleds.com warranty statement page lists older LDM model numbers (LDM060-12050-C21, LDM060P-1250-C21, LDM150P-12416-C23, LDM240P-12500-C24) rather than these LDM…P-12-C2x codes. Order code TMT-105675 (LDM060-12-C21) matches order code 105675 of LDM060-1205-C21 on tmtledsusa.com (see psu-12v-5yr); this may indicate the same product under a new code but no source states it. Order code TMT-105675 is also printed for the 24V 100W unit on the same page (see psu-24v-class2). Wayback Machine could not be queried from this environment, so no first_archived dates were recorded. Datasheets carry no printed date or revision.
