My previous one wasn’t able to keep the voltage, but this one is a perfect match for a video doorbell with continuous streaming. ### ⭐⭐⭐⭐⭐ ottimo *by F***M on 22 January 2025* oggetto perfetto come da descrizione molto robusto ### ⭐⭐⭐⭐⭐ Works well with Botslab R810 Video Doorbell *by R***S on 1 March 2026* After burning out 2x of the 8-24V AC 8VA type transformers, I finally figured out that an 8VA was just not cutting it with my Botslab R810 Video Doorbell and a 40VA was needed. The Vemer VN320800 TMC 40/24 runs silently and cool. As there wasn’t room in my consumer unit I bought a small separate din enclosure to house the transformer. I had to fit the transformer upside down because of the existing wiring. It was quick and easy to fit with a small length of wire acting as a jumper cable to bridge the two connectors to achieve the 24V output. 1 month on after installing the unit is still working exactly as it should. ## Frequently Bought Together - VEMER VN320800 model TMC 40/24 DIN-rail mounting safety transformer for continuous service 230V/12-24V.
