Give your LED strips the steady, silent power they deserve. The 12V 4A (48W) power supply for LED strips — also called an LED transformer, an LED driver or simply a power brick — is the little box that turns your household current into the clean low-voltage power your tape light needs to shine evenly from the first LED to the last. It is the piece people are really looking for when they search for LED drivers or lighting drivers for their LED light strips, whether they are lighting a kitchen counter, a basement stairway, a display case, a home theatre soffit or a storefront window.

Built by LED MONTREAL under model PWR12V4A, this unit delivers a stable 12V DC output at 4A, for a total of 48W, fed by a 120V AC power cable that plugs straight into a standard wall outlet — no hard-wiring, no electrician required for a simple plug-in run. The transformer box measures 11.5 cm long, 5 cm wide and 3 cm high, small enough to hide inside a cabinet, behind a valance or under a shelf. It carries cULus certification for Canada and the USA, so it meets the approvals inspectors and contractors expect on this side of the border. Note that this model is not dimmable on its own: add a controller between the supply and the strip when you want to dim a single-colour strip or change colours on an RGB strip.

This power supply is the right match for the single colour and RGB LED strips in our catalogue, and it earns its place in kitchens, bars, retail displays, offices, workshops and rec rooms across Canada. One important tip before you order: a bigger supply does not automatically mean a longer strip run — always check the maximum circuit length listed for your specific tape light so brightness and colour stay consistent, and never overload the supply. Your package includes the 4A (48W) power supply and its power cable. Add it to your cart and get your strip project lit the right way.

What this power supply does
LED strips do not run on household current. They need low-voltage DC, and that is exactly what this 12V LED power supply provides. It converts the 120V AC from your wall outlet into a clean, regulated 12V DC feed so your tape light turns on instantly, holds its colour and stays free of the flicker and buzz that come with an undersized or unstable source. Think of it as the heart of the installation: choose it correctly and the rest of the system simply works.

Installation and electrical notes
Installation is about as simple as it gets: connect the output leads to the positive and negative terminals of your 12V LED strip (or to the RGB connector), then plug the cable into a standard outlet. Because it is a plug-in unit, it is ideal for renovations where you do not want to open walls or add a junction box. Respect polarity, keep the connection tight, and leave the transformer box where a little air can circulate rather than sealing it inside insulation. Keep it indoors and dry — it is designed for interior use. And remember the golden rule of tape light: add up the watts per foot or per metre of your run and stay within the 48W output, ideally with a margin left over. Overloading the supply will damage it.

Dimming, controllers and compatibility
This model is not dimmable by itself and should not be wired to a wall dimmer. The correct method is to install a controller between the power supply and the strip: a single-colour dimmer controller to vary brightness, or an RGB controller to change colours and run effects. Wired this way, the supply keeps delivering its stable 12V while the controller does the work. It pairs with the single colour and RGB LED strips in our catalogue, and one more reminder worth repeating: upgrading to a larger power supply does not necessarily let you light a longer circuit. Each strip has a maximum run length listed in its own description, and exceeding it causes voltage drop, dimming at the far end and colour shift on RGB.

Where it works and what is documented
Homeowners use it for under-cabinet kitchen lighting, cove and crown moulding accents, closets, stair nosings, bathroom vanities and media walls. Contractors and small businesses put it behind retail shelving, inside display cases, under bar counters, in reception desks and in signage. Because the box is compact, it tucks neatly into a cabinet toe-kick or above a valance. The technical PDF spec sheet for this 12V 4A (48W) power supply for LED strips is available in the Documentation tab of this page, with the certification, input and output details you or your electrician may need for a residential or commercial project.
