VEMER VN319000 model TMC 30/24 DIN-rail mounting safety transformer for continuous service 230V/12-24V. Color Grey

Bought this Vemer transformer to wire up a Reolink Doorbell Camera, and so far it’s been working perfectly.Wiring was pretty straightforward. I used it with a UK 240V mains supply:230/240V supply:Terminal 1 – Live (L)Terminal 6 – Neutral (N)24V AC output to the doorbell:Terminal 7 – Doorbell wireTerminal 12 – Doorbell wireI also used a Wylex WBE3 All Purpose DIN enclosure (Toolstation AE405) to house the transformer, which worked well.Overall, a good quality transformer and exactly what I needed for the installation.

I recently purchased the VEMER VN319000 TMC 30/24 Continuous Operation Transformer for a project requiring a stable 12-24V power supply, and it has not disappointed. The 230V to 12-24V output range is perfect for powering my system, providing just the right amount of power at 30 VA.One of the standout features of this transformer is its continuous operation. It has been running non-stop since I installed it and has proven to be reliable, with no issues with overheating or performance dips. The white color blends in seamlessly with my setup, and the compact design doesn’t take up too much space.Setting it up was straightforward, with clear instructions included. The transformer feels solid and well-built, providing peace of mind knowing that it will perform efficiently over time. It’s also quiet, which is a big plus when used in a workspace or home environment where noise could be a concern.Overall, I’m very satisfied with the VEMER VN319000 Transformer. It’s reliable, efficient, and durable—perfect for any application requiring a stable power source. If you're in need of a dependable transformer for continuous operation, I’d definitely recommend this one.

Had this for 9 months powering a Eufy E340 doorbell, it popped a circuit breaker which I reset. I didn't realise it was this until the battery on the doorbell started dropping.Must of had a major internal failure. The bulges on the plastic are through internal heat, the label has lifted with the plastic. This is the transformer recommended by Eufy, need to look for an alternative.

Purchased in December 2023.Used for Google Doorbell with a separate Honeywell door chimer.Worked perfect for a few years and has now died April 2026. Both outputs provide zero volts.Not sure what failed in the unit but I had hoped it would last longer.

it's dead after less than 2 yrs.....

Easy to fit and does the job I wanted it for

The Unifi Protect G4 Doorbell is by far and away the best consumer video doorbell on the market, and with no ongoing subscription costs, beats the heck out of Ring, Nest & Eufy offerings. Unifi Protect depends upon local video storage - I much prefer this model over the 'someone else's computer' cloud-approach. As of right now though it's targeted at the US market and for US doorbell chime voltages (16 to 24v AC) so requires a bit of thought to work in the UK.Not wanting to miss out here in the UK, and having just moved into a new house which happily had a mains supply near the door from a 30 year old faulty alarm system, I was able to chase in a cable and fused spur switch and fit a 5/6-way DIN enclosure and a Honeywell D117 electromechanical chime box. There are limited 240v mains transformer options available that would fit this setup but the Vemer 30/24 can supply both 24v AC and 12v AC, so along with an AC relay, I was able to supply the Unifi Protect G4 doorbell with 24v AC and the chime box with 12v AC.Everything works a treat, no sign of the 'instant smoke' referred to by other reviewers; one has to suspect user error in those cases though manufacturing faults could also explain it I suppose... though surely they are tested before leaving the factory? Mine seems perfect however and has been happily supplying my video doorbell for a week or more with no problems. A bit pricey but recommended and it should last for years.

Works well with Eufy c31 doorbell. Tested for 2 weeks now.
