Collingwood PSIP70036W 18W-36W 700mA LED Driver - IP65 - Non-Dimmable

A Sealed 700mA Driver for LED Runs That Cannot Take Mains

Plenty of LED fittings will not run straight off the mains. They need a driver sitting between the supply and the light, holding the current steady so the LEDs behave. The Collingwood PSIP70036W does exactly that at a fixed 700mA, feeding anything from 18W up to 36W of connected load. It is sealed to IP65, so it can live in a garden enclosure, under a deck or inside a soffit without needing to be babied.

The 700mA, 36W Unit in Plain Black

Collingwood builds this driver in more than one output size and this is the 700mA version with the larger 36W ceiling. The current is locked at 700mA while the output voltage floats between 25V and 50V DC to suit whatever is connected, which is what allows a single driver to carry several fittings on one run. The body is a compact black plastic moulding, 149mm long, 37mm wide and just 24mm tall, with a lightly ribbed top face and a moulded fixing flange at one end. Nothing about it is decorative. It is designed to disappear behind the lighting it powers.

How It Works

A 220V to 240V mains supply comes in on the brown and blue cores of the input tail. The driver converts that to a smoothed DC output delivered on the red and black cores of the output tail. Both tails are 0.2m of 1mm² two core cable at 7mm diameter, passing through a sealed gland at each end of the case, so in practice you are joining into a weatherproof connector or a junction box close by. Collingwood builds in protection against short circuit, overload and overheating, and quotes 85% efficiency with a power factor of 0.9. The driver is supplied on its own. Fittings, connectors and enclosures are all separate.

Where It Works Best

This is a landscape and exterior driver first. Think spike lights running down a border, ground lights set across a driveway, or step lights on a garden staircase, all fed from one unit instead of a driver hidden beside every fitting. Indoors it does the same job above a ceiling, in a loft void or inside a cabinet plinth. The fixing flange lets it be screwed down to a joist, a batten or the back of an enclosure rather than left hanging on its own cables. IP65 covers dust and water jets, and the product data lists it as suitable for bathroom zone 1, so it can also serve bathroom fittings that need a remote driver. Our guide to bathroom lighting zones sets out how those zones are measured. Wherever it ends up, give it a little air around it and keep it clear of standing water.

About Collingwood Lighting

Collingwood designs and manufactures its LED products at Sywell in Northamptonshire, and it has worked in LED technology and nothing else since 2002. The brand states it was among the first to put fire rated, sealed for life and mains dimmable LED products in front of the UK electrical wholesale trade. It also holds an EcoVadis Gold medal, which places it in the top 5% of the companies assessed worldwide for sustainability.

Good to Know

• Covered by a 5 year Collingwood warranty.
• IP65 means the case is dust tight and protected against water jets from any direction. It will shrug off rain and a hose, but it is not designed to be submerged.
• Class II double insulated construction, so no earth connection is needed at the driver itself.
• Non dimmable. There is no dimming control input, and putting a mains dimmer on the supply side will not dim the fittings and risks damaging the driver.
• Only pair it with fittings that call for a 700mA constant current supply, and total up their wattage first. The combined load has to sit between the 18W minimum and the 36W maximum.
• Rated for ambient temperatures from minus 25°C up to 50°C.
• Body size is 149mm long by 37mm wide by 24mm high, and the unit weighs 0.3kg.
• Care is straightforward. Wipe dust off the case and check the cable glands are still tight whenever the fittings are serviced.
• Moonlight Design recommends installation by a registered NICEIC electrician.

Questions People Ask

What output does the Collingwood PSIP70036W LED driver give?
The Collingwood PSIP70036W is a constant current LED driver with a fixed 700mA output and an output voltage range of 25V to 50V DC. It supports a connected load of 18W minimum up to 36W maximum and runs from a 220V to 240V AC mains supply.

Can the PSIP70036W be dimmed?
No. The Collingwood PSIP70036W is a non dimmable LED driver with no dimming control input, so any fittings connected to it run at full output only. Fitting a mains dimmer on the input side will not dim the light and risks damaging the driver.

Can this driver be installed outdoors?
Yes. The Collingwood PSIP70036W is rated IP65, meaning it is dust tight and protected against water jets, so it is suitable for outdoor garden and landscape installations. It should still be sited where it will not sit in standing water.

How many light fittings can one PSIP70036W run?
That depends on the wattage of each fitting. The Collingwood PSIP70036W handles a total connected load of between 18W and 36W on one 700mA circuit, so six 6W fittings would sit comfortably inside its range while a single 6W fitting would fall below its 18W minimum.

What cables come out of the PSIP70036W?
The Collingwood PSIP70036W has a 0.2m two core 1mm² cable at each end, 7mm in diameter. The mains input arrives on the brown and blue cores and the DC output leaves on the red and black cores, with each tail passing through a sealed gland that maintains the IP65 rating.
