Digitus 19-inch Rack-Mount DIN Rail Panel, 3U
3U · 19-inch35 mm DIN rail · 390 mmSteel · RAL 7035Installation set included
The Digitus DN-19-DIN-3U is a 3U 19-inch rack-mount panel with a built-in 35 mm top-hat DIN rail, so DIN-rail devices — industrial switches, power supplies, PoE injectors, circuit breakers, relays — can be installed neatly inside a standard network or server cabinet.
Instead of building a separate electrical box next to the rack, the panel puts a 390 mm length of DIN rail into three rack units. A rear cable opening and ventilation slots help with wiring and heat, and the panel is made of 1.5–2.0 mm powder-coated sheet steel in light grey RAL 7035, matching most network cabinets.
Before you order: Only 35 mm top-hat (TS-35) DIN devices fit, and the total width of the devices must fit the 390 mm rail. The cabinet needs standard 19-inch profile rails with M6 cage nuts and about 15 cm of free depth.
What's in the Box
- DN-19-DIN-3U panel with integrated 35 mm DIN rail
- Installation set: screws, cage nuts and washers
What It Means in Practice
- Turns 3U of a 19-inch rack into a mini DIN-rail cabinet for industrial and electrical components.
- Keeps DIN-rail PSUs and industrial switches next to the network equipment they serve.
- Rear opening (40 x 35 mm) for feeding cables to the devices.
- Ventilation slots help passively cooled DIN devices.
What Will Not Work
- G-rail or 15 mm mini DIN rail devices.
- Device rows wider than 390 mm in total — consider two panels or the 4U version (DN-19-DIN-4U).
- Racks without 19-inch rails or with less than about 15 cm usable depth.
- It is a mounting panel only: no power distribution, terminals or protection are included.
