Review: Reliable and Efficient: VEMER VN319000 TMC 30/24 Transformer Review - 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.
Review: Transformer for Unifi Protect G4 Doorbell - limited options in the UK but works great - 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.
