Overview: Faithfull Site Transformer - 3.3 kVA, 110V, 16A, 240V Input, Twin Outlet

 

This site unit delivers solid power conversion for industrial tools and equipment. The Faithfull transformer switches your 240V mains into safer 110V output through two 16-amp sockets.

The IP44-rated waterproof case holds up nicely outdoors. It’s rated for continuous loads up to 1.65 kVA, or you can push it to 3.3 kVA for short bursts.

Key Features:

  • Dual outlets for running more than one tool
  • Thermal overload protection to stop overheating
  • Heavy-duty rubber cable with a BS-approved 13-amp plug
  • Centre-tapped to earth for extra safety

 

The 14.2kg weight keeps it stable, but portability isn’t its strong suit. Just be aware that for max loads, it's a 5-minutes-on, 15-minutes-off sort of deal. It won’t run 110V heaters, so that does limit what you can do.

Most customers seem happy with its toughness and how it stands up to daily site work.

Power for Industrial Tools

 

If you’re running pro-grade kit on site, you need reliable conversion. The Site Transformer delivers steady juice to demanding tools, thanks to its twin outlets.

Key Power Features:

  • 16 amp capacity—handles beefy equipment
  • Twin socket system—run a couple of tools at once
  • 240V to 110V conversion—meets UK site safety rules

 

People seem to like that it powers angle grinders, drills, and circular saws without voltage sag. The 3.3 kVA rating is enough for most jobs.

That said, the 14.2kg heft means you won’t want to lug it too far. The thermal overload protection is a nice safeguard if your tools get a bit greedy with current.

The waterproof case handles rough conditions, but a few users wish the plug connections felt a bit sturdier, especially if you’re constantly swapping tools.

Weatherproof and Durable Construction

 

This transformer’s build is genuinely robust, with a heavy-duty GPR case and that IP44 rating. The waterproofing keeps out rain and dust, so it’s good for most outdoor jobs.

Weighing in at 14.2kg, it’s solid—and you feel it. The 30 x 26 x 23 cm footprint isn’t massive, but you’ll notice it in the van.

Key Construction Features:

  • IP44-rated waterproofing
  • Heavy-duty GPR case
  • 14.2kg for extra stability

 

The thermal overload protection is another layer of safety, but remember, it’s still meant for intermittent use—5 minutes on, 15 off.

With a max ambient temp of 20°C, it could get a bit warm in hot weather. And just to be clear, it’s weatherproof, not waterproof as in “drop it in a puddle and forget about it.”

Twin 110V Outlets for Enhanced Productivity

 

Two 110V outlets really do make a difference when you’re juggling tools. The Site Transformer’s dual 16-amp sockets mean you can run two bits of kit at once—no more constant plug swapping.

This is handy for small crews or when you’re multitasking. It just saves hassle.

Key benefits:

  • Simultaneous operation—run a couple of tools together
  • 16-amp per socket for most gear
  • Time-saving—less plug faff

 

Heads up though: if you’re running two high-power tools at once, you’re splitting that 3.3kVA between them. Each tool gets a bit less power than if you just used one outlet.

The twin socket setup definitely helps with workflow, but just keep your total power needs in mind if you’re maxing it out.

Advanced Safety Features

 

Safety’s not an afterthought here. The transformer comes with re-settable thermal overload protection, so if it gets too hot, it’ll cut out and save your tools (and itself).

The IP44 rating means it shrugs off dust and splashes—no worries about the odd downpour or muddy site.

The heavy-duty rubber cable and BS-approved 13 amp plug add a bit of extra reassurance. You get a 2-metre cable, which is decent, though not exactly generous.

The solid GPR case shields the guts from knocks and scrapes, unlike some of the cheaper options out there. It’s pretty reassuring if you’re not the most gentle with your kit.

Downside? That 14.2kg weight again—it’s a bit of a lump. But honestly, that’s what you get for a transformer that’s built to last.

Ease of Use and Portability

 

Setup’s straightforward. The Faithfull transformer comes ready to plug into any standard 240V socket with its 2-metre rubber cable. The twin 110V outlets are pretty convenient—no need for extra adapters.

The self-resetting thermal overload means you’re not hunting for fuses if it trips. That’s a real time-saver when you’re busy.

Portability challenges:

  • Heavy—not a one-person lift for most
  • No handles or wheels—could be easier to move
  • Bulky—takes up space in the van

 

The tough IP44 case is built for rough sites, but you’ll want to plan ahead for moving it. Most people will use a trolley or get a mate to help. The 2-metre cable’s fine for most setups, but if you’re working far from a socket, you’ll probably need an extension.

Manufacturer Guarantee

 

This transformer comes with a standard one-year Power Plus guarantee from Faithfull. It’s not mind-blowing, but it does give you a bit of peace of mind.

The warranty covers manufacturing faults and dodgy components for the first year. That includes the transformer itself and key safety bits like the thermal overload.

What's Good:

  • Full year’s cover from a known brand
  • Protection against manufacturing issues
  • Covers vital safety features

 

What Could Be Better:

  • One year’s pretty standard, nothing special
  • Warranty details are a bit vague in the info provided

 

For gear that takes a beating on site, having any manufacturer backing is worth something. The year should catch early problems, but if you’re after long-term cover, you might be left wanting more.
