คำตอบด่วน: For a commercial facade with a verified 230VAC feed and three 24V LED runs totaling 120W, the WEHO HLG-150-24 is a defensible first-stage choice. Its current enterprise-drive sheet states a 150W single-output supply and lists the 24V model at up to 6.3A. The worked load draws 5.0A, leaving 1.3A against the current limit and 30W against the stated power limit. Both limits apply. That is not final design approval; confirm LED-strip voltage, startup behavior, cable drop, thermal conditions, weatherproof connections, and the exact ordered revision.
Architectural facade lighting is a system problem, not simply a request for a “150W waterproof LED driver.” A buyer needs to know how many 24V runs operate together, how long the conductors are, where the power conversion sits, and whether the installation is exposed to rain, heat, or maintenance damage. This example uses a commercial building’s linear facade lighting, not a generic LED strip on a bench.
WEHO’s English HLG-150 product page identifies the exact series and includes HLG-150-24 in its detailed model table. Because the page’s introductory copy contains inconsistent model data, it is not used as the controlling electrical source. The exact HLG-150-24 selection is supported by the current HLG-150 specification in WEHO’s enterprise drive and by the photographed product label. That order matters: application first, model second, real product image third.
Translate the lighting schedule into a load
Assume the lighting designer has specified three independently routed, 24V constant-voltage LED runs that may operate simultaneously. The values below are a worked procurement example, not a claim about a particular building or LED tape.
| 24V facade run | Verified design load for example | Current at 24V |
|---|---|---|
| Entrance canopy line | 40W | 1.67A |
| Stone reveal line | 40W | 1.67A |
| Upper ledge line | 40W | 1.67A |
| Concurrent total | 120W | 5.00A |
The HLG-150-24 sheet states a 150W single-output supply and gives the 24V model a 0–6.3A output range. Evaluate both ceilings rather than converting 6.3A into a higher usable power rating. The 120W example uses 80% of the stated 150W limit and 5.0A of the 6.3A current limit, leaving 30W and 1.3A on the first arithmetic screen. Neither difference is free capacity for an unmeasured fourth run. LED modules, controllers, inrush, temperature derating, and future extensions must all be accounted for.
The selection is specifically for a 24V constant-voltage load. If the specified luminaires require a constant-current driver, a different voltage, or a proprietary dimming/control interface, the HLG-150-24 cannot be approved merely because the wattage appears close.
Why the 150W class is plausible here
The exact model is neither chosen as a habit nor sized from the visual length of the facade. The stated 120W concurrent load fits beneath the HLG-150-24’s documented 6.3A output, whereas an unmeasured or longer LED schedule does not. The site feed in this worked example is explicitly 230VAC; the product photo and current sheet agree on the 24V/6.3A output. Final use at another input condition requires checking the ordered unit’s label and revision.
The current enterprise-drive sheet records an exterior envelope of 170 × 69 × 43 mm (length × width × height). Its drawing also shows a 145mm central body within the 170mm overall mounting length and cable exits at opposite ends. Allow additional space for cable routing, bend radius, junction boxes, service access, and the manufacturer’s mounting instructions; the 170mm number is not a total installation clearance.
A publicly indexed HLG-150 PDF is internally inconsistent: its page-top product callout states 190 × 49 × 34 mm, while the table and mechanical drawing on that same PDF state 170 × 69 × 43 mm. This article uses the current enterprise-drive specification, which records 170 × 69 × 43 mm and provides the matching drawing. Procurement should still obtain the mechanical drawing for the exact ordered revision before drilling the facade support.
Separate waterproof housing from waterproof installation
An IP67-marked driver can be appropriate for a demanding outdoor lighting environment, but the complete installation is only as robust as its cable entries, connectors, junction boxes, mounting, drainage, and maintenance practice. Specify weather-rated joints and strain relief for the actual exposure. Do not leave AC conductors, DC splices, or cut cable ends exposed under a ledge and assume the driver enclosure rating protects them.
The rendered product views are visual aids checked against the verified source photograph and current 170 × 69 × 43 mm specification. They are not construction drawings. Confirm the required local code, protective earth/bonding arrangement, isolation, upstream protection, and any lighting-control requirements with the installer and current ordered instructions.
Check voltage at the farthest LED run
At 24V, conductor drop can be noticeable on a long facade. For each branch, calculate the complete outgoing-and-return conductor resistance at operating temperature and multiply it by that branch’s worst-case current. Add relevant connector and distribution losses. Measure voltage at the most remote LED module under full concurrent load and compare it with the LED manufacturer’s allowed operating range. A bright first section and dim last section is a distribution problem, not necessarily a driver defect.
Split long runs or feed them at appropriate points when the lighting design requires it. Do not simply turn up output voltage to compensate for a weak cable route: the near-end luminaires may then be over-volted. Verify whether the ordered HLG-150-24 revision allows any adjustment before specifying one.
Commission for the real duty cycle
Record the actual 230VAC site input, worst simultaneous 24V current, driver temperature, far-end LED voltage, switching/startup behavior, and the lighting controller’s operating sequence. Inspect the sealed connections after installation and after a representative wet/thermal cycle. If the facade is divided into separately maintained zones, document each driver’s branch and replacement model so a later repair does not silently exceed the original budget.
ประเด็นสำคัญ
- A three-run, 120W example draws 5.0A at 24V; against the sheet’s stated 150W and 6.3A limits, it leaves 30W and 1.3A on the first arithmetic screen.
- Match constant-voltage/constant-current requirements and any dimming interface before selecting a model.
- Use the current enterprise-drive 170 × 69 × 43 mm drawing for this review; the public PDF contains conflicting size callouts, and the ordered revision still requires verification.
- Waterproof housing does not make exposed connectors or splices waterproof.
- Cable drop, heat, startup, protection, and measured commissioning results decide final suitability.
บทสรุป
For the defined 230VAC, 24V, 120W facade-lighting example, the HLG-150-24 is a reasoned candidate rather than a default 150W image choice. An OEM or contractor should release it only after the exact LED schedule, cable design, outdoor connection detail, and ordered mechanical revision are confirmed.
คำถามที่พบบ่อย
How much 24V load can the HLG-150-24 supply?
The current enterprise-drive sheet lists 24V at up to 6.3A, or 151.2W by multiplication. Apply the ordered revision’s temperature and installation limits before release.
Is the 120W facade example an actual WEHO project?
No. It is a clearly marked worked example of three simultaneous 40W lighting runs. Replace it with the project’s LED schedule and measured currents.
Does an IP67 driver make every outdoor splice waterproof?
No. Cable joints, glands, connectors, strain relief, and enclosures need their own exposure-appropriate protection.
Which HLG-150 dimensions should an installer use?
This review uses the current enterprise-drive drawing at 170 x 69 x 43 mm. An older public PDF differs, so confirm the exact ordered mechanical revision before drilling.
Can I fix far-end LED dimming by increasing supply voltage?
Do not assume so. Calculate outgoing-and-return conductor drop and confirm both near-end and far-end LED voltage limits first.
