NewTrend · IP67 constant-voltage LED power supply
Product overview
The MV-350-24 is a nominal 350 W waterproof switching power supply with a fixed 24 V DC output, rated 14.6 A on its product nameplate. It accepts AC 180–264 V at 50/60 Hz. The compact aluminium housing is filled with sealing compound to protect the internal electronics against dust and moisture.
The unit supplies compatible constant-voltage LED lighting, signs and low-voltage security equipment. Built-in short-circuit, overload and overvoltage protection support self-recovery after the fault has been removed.

Dimensions and mounting
The dimension drawing identifies a 235 mm overall length, 120 mm width and 56 mm height, with a 220 × 101 mm mounting-hole spacing. The mounting tabs have six R2.1 slots. Input and output leads are marked 270 ±20 mm long, using 18 AWG (0.75 mm²) conductors. Leave clearance for cable bends and secure the unit through the mounting tabs.
Sealed aluminium construction
The glue-sealed aluminium shell combines environmental protection with heat dissipation through the case. PWM control and a half-bridge arrangement provide the AC-to-DC conversion. Natural convection provides cooling; keep the housing clear of insulation and allow air circulation.
The operating-temperature range is −40°C to +65°C, with a maximum case temperature of 60°C. Protect the external cable joints separately, and isolate the supply before installation or servicing.
Input and output wiring
The illustrated input uses brown for live (L), blue for neutral (N) and yellow/green for protective earth (PE). Connect the red output lead to DC positive and the black lead to DC negative. The wiring diagram shows the AC input and three DC output pairs sharing the rated total output current. Match the load voltage and polarity before energising the unit.
Protection and typical applications
Short-circuit, overload and overvoltage protection use self-recovery. Clear the connected-load fault before returning the installation to service.
- Compatible 24 V LED strips, light modules and outdoor signs.
- Low-voltage security and CCTV equipment.
- Architectural, landscape and public-lighting installations requiring a 24 V constant-voltage source.
