PHILIPS Frameless LED Panel RC468V LED34/950 W60L60 PSD GC
PHILIPS 28 W 3,500 lm 5000K UGR <22 PSD / DALI IP54 front 50,000 h
The DALI-dimmable version of the 28 W frameless module: 3,500 lm, 5000K, UGR below 22, with a PSD driver that is addressed and dimmed from the lighting control system rather than from a wall switch. Same 599 × 599 mm body as the PSU code. Part of the PHILIPS RC468V frameless panel series, and listed on the PHILIPS LED panel range page.
What 911401904080 Gives You
Dimmable on a DALI Bus
The PSD driver takes a digital dimming signal from the control system, so the panel becomes part of a scheme rather than a fixed load: daylight linking, occupancy dimming, time schedules, scene recall.
Addressable Per Fixture
Each luminaire carries its own address. You can dim a row facing a window differently from the row behind it, which is the whole point of putting a sensor on the facade.
Identical Body to the PSU Code
Same 599 × 599 mm footprint, same 58 mm depth, same 270° edge emission. A layout drawn around the PSU code can be upgraded to DALI without redrawing the ceiling.
UGR Below 22
Glare control is unchanged by the driver choice. Swapping PSU for PSD does not shift the UGR figure, so the comfort argument survives the upgrade.
Where This Code Sits in the Range
DALI at the 28 W output. If the scheme has no control system, the fixed-output 911401904070 is the same luminaire for less money and less cable. If the driver of the system also has to shift colour temperature, that is the tunable white code 911401904088.

|---|---|---|---|---|---|

| 911401904574 | RC468X LED42/950 W60L60 FL GC | 35 W | 4,300 lm | 5000K | FL |
All five codes share the 599 × 599 × 58 mm body, the 270° edge emission and the IP54 luminous face. What changes between them is output, colour temperature and driver.

Ingress protection is quoted against IEC 60529: IP20 for the housing, IP54 for the sealed luminous face. UGR values follow the CIE unified glare rating method; see CIE for the calculation basis.
Driver and Control
Driver version on this code: PSD — DALI-dimmable, addressable per fixture. The driver is supplied as part of the 12NC, not chosen separately at the counter.
It sits on the back of the module. Panel height is 58 mm on its own and stays under 70 mm once the driver is mounted, which is what lets the module sit inside a standard ceiling void without a spacer.
Where the scheme needs a different control layer, the same 3,500 lm module is available as PSU or PSD / DALI. Driver and system compatibility questions are best answered from the datasheet for the batch you are quoting — ask us and we will send it with the quotation.
Splicing, Mounting and Accessories
Four mounting methods are supported on the same module: integrated ceiling grid, plasterboard recess, rod suspension and spliced runs. Splicing is what the frameless edge is for — two modules butted together read as one continuous luminous plane, and the joint does not need a trim strip to close it. Mounting hardware is ordered as separate accessory codes:
| 12NC | Description | Pack | For |
|---|---|---|---|
| 911401904090 | RC468Z CPC Strip AC Kit | 8 pcs | Spliced runs |
| 911401904091 | RC468Z Profile Clip 4040 AC Kit | 16 pcs | Profile mounting |
| 911401904092 | RC468Z Suspension Clip AC Kit | 16 pcs | Rod suspension |
Accessory quantities in the table are per kit, not per module. Work out kit count from the number of joints, profile lengths and drop points in the layout. The series page carries the dimensional drawing and the full mounting description.
Product Image and Photometrics
Dimmed as a planeThe DALI version dims the whole run together, so a spliced ceiling holds one light level instead of stepping fixture by fixture.
Polar intensity distribution
L.O.R. 1.00 — symmetric in the 0–180° and 90–270° planes. Measured IES, LDT and ULD files are issued with the quotation.
Indicative shape, measured filesThe lobe shows the form of the distribution; the numbers live in the IES and LDT files, so your calculation never runs on a traced scan.
Ordering
| Item | Value |
|---|---|
| Order code (12NC) | 911401904080 |
| Factory description | RC468V LED34/950 W60L60 PSD GC |
| Output / CCT | 3,500 lm / 5000K |
| Driver | PSD (DALI) |
| Body | 599 × 599 × 58 mm frameless, IP54 luminous face |
Quote and order by the 12NC. Colour temperature is carried by the digits after the slash in the factory description (940 = 4000K, 950 = 5000K, 965 = 6500K), so a description that looks similar but reads 940 is a different code and a different colour.
Frequently Asked Questions
What control equipment does 911401904080 need?
A DALI controller or application controller on the same bus, plus the bus wiring itself — DALI is a two-wire bus and does not need a separate dimming pair. The fixtures are addressed from the controller, so the bill of materials is the panels, the controller and the bus. We can supply a wiring schedule for the layout if you send the reflected ceiling plan.
Is the driver DALI-2 certified?
Do not assume it from this page. DALI-2 certification is granted per driver, per device type, and the certificate number sits on the driver datasheet rather than on the luminaire code. Ask us for the driver datasheet for the batch you are quoting and check the number against the certification database maintained by the Digital Illumination Interface Alliance before you write it into a specification.
Can I mix PSD and PSU modules on one run?
Physically yes, electrically no. A PSD fixture on a switched circuit will only ever be fully on or off, which defeats the point; and a mixed run cannot be commissioned as one group. Keep dimmable and fixed-output codes on separate circuits, or standardise the whole run on 911401904080.
