NewTrend · IP67 waterproof switching power supply
Product overview
The SMV-200 is a constant-voltage outdoor power supply in a fully glue-sealed aluminium case. It converts AC 180–264 V mains into a stable DC output of 200 W at 12 V or 24 V, and is built for outdoor LED lighting, CCTV and signage where the driver has to survive rain, dust and wide temperature swings.
The sealed housing carries an IP67 rating, so the electronics are protected against dust ingress and against temporary immersion. The shared source description lists a ±10% voltage-adjustment range, but the photographed sealed unit does not show an external adjustment control. An adjustment method has not been verified.
Sealed aluminium construction
The case is extruded aluminium filled with potting compound, which combines heat dissipation with sealing. The supplier states that the marked power equals the actual output power, and that the ribbed housing keeps the case temperature inside the stated limit.
The input and output leads are moulded into the case, so no separate gland or terminal cover is needed. Fit the unit with the cable entries pointing downwards, and do not bury the driver or install it in a pit.
Electrical specifications
The values below come from the product data sheet supplied with the source material and from the markings on the photographed 200 W unit. Where the two disagree, the unit marking and the dimension drawing are followed.
| Models on this page | SMV-200-12 (12 V DC) and SMV-200-24 (24 V DC) |
|---|---|
| Rated output power | 200 W |
| Output voltage | DC 12 V or DC 24 V, depending on the selected version |
| Rated output current | 24V version: 8.3A on the photographed nameplate. A 12V-version nameplate/current rating has not been verified. |
| Shared adjustment reference | ±10% in the shared description; adjustment method not verified for the photographed sealed unit. |
| Output-voltage accuracy — unverified | The source states “98%” without a tolerance definition or test conditions; this is not adopted as a verified voltage-accuracy specification. |
| Output ripple and noise | 120 mVp-p |
| Input voltage | AC 180–264 V, 50/60 Hz |
| Input current | 2.0 A, as marked on the unit label |
| Efficiency | 89 % |
| Protection class | IP67, fully glue-sealed aluminium case |
| Protection functions | Short circuit (SCP), overload (OLP) and over-voltage (OVP), all with self-recovery |
| Cooling | Free air convection |
| Operating temperature | −40°C to +65°C in the shared source description; the separate stated maximum case temperature is 60°C. Permissible load and temperature conditions require confirmation. |
| Maximum case temperature | 60°C in the shared description; this conflicts with the listed +65°C ambient endpoint unless additional conditions apply. No full-load +65°C operation is established. |
| Housing | Aluminium shell with glue filling |
| Dimensions (drawing) | 240mm overall length; 216mm case length; 43mm height. Width: drawing 69mm / caption 68mm — requires confirmation. |
| Input cable | 18 AWG (0.75 mm²) × 3C, 270 ± 20 mm |
| Output cable | 14 AWG (1.5 mm²) × 2C, 270 ± 20 mm |
| Mounting | Six R2.1 mounting-slot features; drawing shows a 12mm end mounting section. The 8mm labels refer to wire ends. |
AC input and DC output wiring
Connect the mains supply to the three-core input lead: L (brown), N (blue) and PE (yellow-green). The two-core output lead provides +V (red) and −V (black) to the load. The output is a constant-voltage DC source, not a constant-current driver; for LED loads that require a constant current, use a suitable constant-current driver instead.
The photographed 24V unit marks an AC input current of 2.0A. The required circuit protection, cable sizing and voltage-drop allowance depend on the installation; the shared adjustment claim does not establish an accessible field adjustment.
Protection functions
The original description lists short-circuit, overload and overvoltage protection with self-recovery. It does not specify the fault thresholds or whether the output uses shutdown, current limiting or restart cycling, so no particular protection sequence is claimed here.
Dimensions and cable lengths
The drawing gives an overall length of 240mm, a case length of 216mm and a height of 43mm. Its width dimension reads 69mm, while the red size caption reads 68mm; these references disagree and the width requires confirmation. The 8mm annotations are at the wire ends, not the mounting brackets. The drawing also shows a 12mm end mounting section and six R2.1 mounting-slot features. Input and output leads are each 270 ± 20mm long.
The written data sheet in the source material gives 235 × 120 × 56 mm and a weight of approximately 2.4 kg. Those figures do not match the drawing of the photographed 200 W unit, so this page follows the drawing and does not state a weight. Check the actual unit before finalising an enclosure layout.
Typical applications
Outdoor LED lighting and signage, security-camera and access-control supplies, and general outdoor DC distribution where a sealed, convection-cooled 12 V or 24 V source is required. The illustrated application fields are examples rather than certifications for those industries.
Available versions
This listing covers the 200 W unit in the two output voltages offered by the source: SMV-200-12 for DC 12 V and SMV-200-24 for DC 24 V. Other power ratings of the SMV series (30 W to 350 W) are separate products and are not selectable on this page.
