Engineering Shield Waterproof Series Power Supply

Sealed Construction & Protection

• Full-potting, not a surface coating — the housing is filled with resin after assembly, so the board and its components sit inside a solid mass instead of in air that carries humidity and dust.
• IP67 protection — fine dust cannot enter the housing, and the unit is protected against water exposure at the position where it is mounted. That build is what makes this an IP67 LED power supply rather than a sheltered indoor model.
• Moisture and dust stay outside — rain, spray and condensation are the usual cause of early failure in outdoor drivers; potting keeps them away from the components instead of relying on a coating over the board.
• Sealed cable entry — the cable leaves through the sealed housing. Keep the gland tightened and the jacket undamaged, because that is where outdoor units most often lose their protection.
• Heat path through the housing — with the enclosure filled, heat spreads into the housing wall rather than building up in trapped air, which suits sign boxes and fixtures where airflow is limited.

Specifications

Outdoor Applications

• Billboards and roadside signage — this outdoor LED power supply sits inside or behind the frame, where rain, dust and traffic spray reach it every day. There is no separate weatherproof box to buy, wire and seal.
• Sign cabinets and channel letters — an LED sign power supply fitted inside a shopfront or forecourt sign, protected from the damp that collects in sealed metal housings.
• Landscape and garden lighting — uplighters, path lighting and tree accents on long outdoor runs, where the unit is usually fixed to a wall or set into a service box.
• Pool and water-feature surroundings — pool-side lighting is one of the environments this series is specified for. Mount the unit above water level and let water drain away instead of pooling around the housing.
• Façade and architectural lighting — smaller outdoor circuits on commercial buildings, where the driver has to last years of weather without being serviced.

Output Power & Voltage Matching

1. Match the voltage first. This 24 V LED driver feeds loads rated at 24 V. A 12 V strip or module will not run correctly on it, and mixing voltages on one circuit is not an option.
2. Add up the load. Total the rated wattage of every strip, module and fixture on the circuit, then compare that figure with the model you are considering.
3. Leave planning margin. Outdoor circuits often run for long daily hours, so allow headroom above the calculated load for start-up current, voltage drop along the cable and any fixtures added later.
4. Check the run length. The driver holds a steady output at its terminals, but on a long feed the voltage at the far end can sag; heavier cable or a larger rating keeps the last fixture as bright as the first.
5. Confirm before you commit. Send us the load schedule with the mounting position and we will check it against the range — an outdoor LED power supply that runs at full output for hours should be sized with margin rather than pushed to its limit.

Installation & Cable Entry

Mount the unit where water drains away instead of collecting — under a ledge, inside the frame, or on a bracket clear of standing water. Keep the housing closed: the potting is what gives the unit its protection, so never drill or cut the case to pass a cable through it, and use the sealed cable entry provided. Face the cable entry downward and form a short drip loop so water runs off the cable rather than tracking into the gland. On billboards and pole-mounted signs, fix the unit against vibration and leave a little room around the housing for heat to escape. Before power-up, check the polarity and confirm the load is rated for 24 V. If the mounting position is tight, send us the dimensions — as an LED driver manufacturer we can usually tell from a photo whether the unit will sit correctly.

Scale & Supply Capability

We are a China-based LED switching power supply manufacturer supplying wholesale and project buyers. Our portfolio covers a wide range of series, so you can source stable constant-voltage drivers, 12V/24V auto-sensing units, fully potted waterproof models for outdoor signs and landscape lighting, brightness-controlled units for advertising signs, and magnetic-mount versions for secure indoor installation — all from one supplier. Wholesale supply is available. Share your application and voltage requirement, and we will point you to the series that suits your order.
