## Description

VEMER VN321600 Transformer TMD 30/24 Din Bar for Discontinuous Service 230V/12-24V Power 30A, lightgrey : desertcart.co.uk: Automotive

Review: Ideal supply for Eufy doorbell. - The ideal power supply for a Eufy doorbell. Due to its high power output, it can be used with very long cable runs. It fits all standard DIN rails and is super easy to connect and select the correct voltage/power. Mines running constantly over two years-no issues excellent durability. However, this should still be installed by a qualified electrician, not as a DIY project.
Review: Ideal for Eufy E340 but read my comments first, - Purchased for a Eufy E340 video doorbell but after reading some of the reviews was a bit concerned as to the higher than permissible voltage at the output, the spec’ did seem ideal so purchased anyway and conducted my own tests. Under no load the 24V tapping does indeed record 31V but this would drop according to the load at these terminals. To play it safe I utilised the centre tapping which read 15.6V under load and was an ideal trade off, all connected and running perfectly so if you are concerned about possible damage to your Eufy I would suggest connection to the first and third terminals from the left as in the images.
