NewTrend · Compact IP67 LED power supply
Product overview
The SMV-120 is a compact, 120 W nominal constant-voltage switching power supply for compatible LED lighting, signage and security equipment. The glue-sealed aluminium enclosure carries an IP67 protection rating. Select SMV-120-12 for a fixed 12 V DC output or SMV-120-24 for a fixed 24 V DC output. Both versions accept AC 180–264 V, 50/60 Hz.
Product photographs show the SMV-120-24 version, marked 24 V DC and 5 A. The 12 V version is rated 10 A.

Sealed enclosure and protection
The aluminium housing is filled and sealed to protect the electronics against dust and moisture. Heat dissipates through the casing by free-air convection. Keep the external cooling surfaces clear and allow ventilation around the unit. Built-in short-circuit, overload and overvoltage protection use self-recovery; remove the fault before restoring the connected equipment.
The operating-temperature range is −40°C to +65°C. Protect cable joints separately and avoid touching the housing when hot.
Input and output wiring
The wiring illustration identifies brown as AC live (L), blue as neutral (N), yellow/green as protective earth (PE), red as DC positive (+) and black as DC negative (−). Isolate the supply before wiring, provide the appropriate protective-earth connection, and match the load voltage and polarity to the selected model.
Dimensions and installation
The drawing shows an overall enclosure size of 185 × 69 × 43 mm, a 161 mm mounting-hole spacing and six R2.1 mounting slots. Input and output leads are marked 270 ±20 mm long. Leave room for the leads to bend without strain and keep connections protected against moisture.
Typical applications
- Compatible 12 V or 24 V LED strips and outdoor signs.
- CCTV cameras and low-voltage security equipment.
- Auxiliary lighting and compatible control equipment.
