Its double isolation ensures maximum user safety, while the compact 3 DIN-module design allows easy rail mounting in electrical panels. Ideal for powering low voltage devices like video doorbells and industrial controls, it operates silently and remains cool under load, making it a reliable choice for professional and home installations. ## Description From the manufacturer Modular transformers for continuous service Modular safety transformers for continuous service, intended to power devices and circuits with very low safety voltage. General characteristics The double isolation separating the primary and the secondary allows you to limit, in the powered circuit, damage resulting from accidental contacts with electrically active parts or masses that can go into voltage in the event of a fault of the insulation. The overload or short-circuit condition may damage the appliance but does not determine the hazard condition for users or adjacent parts. Review: Works well with Botslab R810 Video Doorbell - 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. Review: Eufy E340 - I got this to power my Eufy E340, been running about two months without any issues. Would highly recommend. ## Features - Voltage primary: 230 V AC - Secondary voltage: 12 – 24 V AC - Power: 40 VA - Size: 3 DIN modules ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00F4QIL06 | | Best Sellers Rank | 21,120 in DIY & Tools ( See Top 100 in DIY & Tools ) 2,642 in Electrical | | Brand | VEMER | | Country Of Origin | Italy | | Customer Reviews | 4.2 out of 5 stars 147 Reviews | | Item Weight | 0.6 Kilograms | | Item weight | 0.6 Kilograms | | Manufacturer | Vemer | | Manufacturer Part Number | VN320800 | | Minimum Frequency | 50 Hz | | Model Number | VN320800 | | Mounting Type | Rail Mount | | Mounting type | Rail Mount | | Number of items | 1 | | Power Source | Corded Electric | | Power source | Corded Electric | | Specification Met | din | | Specification met | din | | Unit Count | 1.0 count | ## Product Details - **Brand:** VEMER - **Item weight:** 0.6 Kilograms - **Mounting type:** Rail Mount - **Power source:** Corded Electric - **Specification met:** din ## Images ![VEMER VN320800 model TMC 40/24 DIN-rail mounting safety transformer for continuous service 230V/12-24V.

I consider there is design problem. I had to return the item. ## Frequently Bought Together - VEMER VN320800 model TMC 40/24 DIN-rail mounting safety transformer for continuous service 230V/12-24V.
