Mean Well power supplies for automation cabinets
Mean Well is used in automation cabinets when the panel needs a clear DC source for PLCs, HMIs, sensors, relays, valves or LED lines. The common requests are straightforward: 24 V for automation, 12 V for lighting and auxiliary circuits, 48 V for heavier loads. The Chastotnik.ua catalogue includes Mean Well models with 5, 12, 24, 36 and 48 V outputs, 85-264 V input and two mounting formats: DIN rail or enclosed terminal-block case.
If you need the whole equipment group rather than only this brand, open industrial power supplies. This page focuses on Mean Well: LRS, HDR, MDR, DR, NDR and RSP. The difference is not just the series name. It is mounting, current headroom and how the supply behaves in a cabinet with several DC consumers.
Which Mean Well series to choose
| Series | Catalogue range | Mounting | When to use it |
|---|---|---|---|
| LRS | 50-350 W, 12/24/36/48 V | Enclosed case | A cost-conscious supply for cabinets, LED lines, relays and general 24 V loads. |
| HDR | 15-100 W, 12/24/48 V | DIN rail | For panels with little free space. Slim body, easy to mount near breakers. |
| MDR | 20-100 W, 5/12/24/48 V | DIN rail | For sensors, relays, a small PLC or auxiliary 5 V supply. |
| DR | 15-120 W, 12/24/48 V | DIN rail | A classic automation option when large power headroom is not required. |
| NDR | 75-480 W, 12/24/48 V | DIN rail | For loaded cabinets where several consumer groups sit on the 24 V bus. |
| RSP | 500 W, 12/24/48 V | Enclosed case | For high current in an enclosed case when a DIN-rail format is no longer enough. |
24 V model examples
24 V is the usual choice for industrial automation. Count more than the PLC: contactor coils, I/O modules, relays, sensors and cable length all matter. These are practical reference points from the catalogue, without tying the choice to price.
| Model | Power | Current | Format | Typical use |
|---|---|---|---|---|
| HDR-60-24 | 60 W | 2.5 A | DIN rail | Small cabinet, HMI, sensors, relays. |
| MDR-60-24 | 60 W | 2.5 A | DIN rail | Compact automation where tidy mounting matters. |
| DR-120-24 | 120 W | 5 A | DIN rail | PLC with peripherals, several relay groups. |
| NDR-240-24 | 240 W | 10 A | DIN rail | Control cabinet with several 24 V consumers. |
| LRS-350-24 | 350 W | 14.6 A | Enclosed case | High-power 24 V supply without a DIN-rail body. |
What we check before ordering
First: output voltage. Most automation cabinets use 24 V, LED and separate modules often use 12 V, and long lines or specific loads may need 48 V. Second: current. A 2.5 A unit should not carry everything in the panel; leave headroom, especially with coils, relays or pulsed loads.
Third: mounting. DIN-rail HDR, MDR, DR and NDR are convenient for electrical panels. LRS and RSP are usually chosen in an enclosed case when power matters more than rail compactness. To compare another brand, open Delta power supplies. If the headroom is unclear, send us the list of cabinet consumers: we will calculate the current and suggest a series without oversizing the supply.
