Schneider Electric power supplies for automation cabinets
Schneider Electric units are used in control cabinets when the panel needs stable DC power for Modicon PLCs, HMI panels, sensors, relays and contactor coils. The Chastotnik.ua catalogue groups them into three families: compact modular ABLM, the 24 V workhorse ABL2 (Easy Modicon) and the higher-power Phaseo ABLSU. Outputs are 5, 12, 24 and 48 V, with 100-240 V input for single-phase models and 380-500 V for three-phase units.
If you need the whole section rather than one brand, see industrial power supplies. This page focuses on Schneider: how the series differ, where the input is single-phase and where three-phase, and how much power to choose for the real load of the panel.
Which Schneider series to choose
| Series | Catalogue range | Input / mounting | When to use |
|---|---|---|---|
| ABLM | 10-60 W, 5/12/24 V | 1-phase, DIN-rail | Compact power for sensors, relays, a small PLC and 5-24 V auxiliary circuits. |
| ABL2 | 36-351 W, 24 V | 1-phase, DIN-rail | The 24 V workhorse for control cabinets: PLCs, I/O modules, contactors. |
| ABLSU (ABLS1A) | 50-480 W, 12/24/48 V | 1-phase, DIN-rail | Phaseo with a wider voltage range and current headroom for busy panels. |
| ABLSU (ABLU3A) | 120-960 W, 24/48 V | 3-phase 380-500 V, DIN-rail | For sites with a three-phase supply that need high power with balanced phases. |
Example 24 V models
24 V is the standard for industrial automation. Count not only the PLC but also contactor coils, I/O modules, relays and sensors, and keep current headroom. Below are catalogue reference points, without tying them to price.
| Model | Power | Current | Input | Typical use |
|---|---|---|---|---|
| ABLM1A24025 | 60 W | 2.5 A | 1-phase | Sensors, relays, a small automation node. |
| ABL2REM24045K | 108 W | 4.5 A | 1-phase | Modicon PLC with peripherals, relay groups. |
| ABL2REM24085K | 200 W | 8.3 A | 1-phase | A busy 24 V control cabinet. |
| ABLS1A24100E | 240 W | 10 A | 1-phase | Phaseo for several 24 V consumer groups. |
| ABLU3A24200 | 480 W | 20 A | 3-phase | High 24 V power from a three-phase supply. |
What to check before ordering
First, the input type. With a single-phase 220 V supply, choose ABLM, ABL2 or the single-phase ABLS1A. With a three-phase 380-500 V supply and a need for high power, look at the three-phase ABLU3A, which loads the phases evenly. Second, the output voltage: 24 V for automation, 12 V for auxiliary circuits, 48 V for longer lines. Third, the current: do not load a unit to its limit without headroom, especially with coils and inrush loads.
Fourth, the mounting: every series here is DIN-rail, so it sits in the panel next to the breakers. To compare with another brand, open Mean Well power supplies or Delta. If you are unsure about headroom and input type, send us the list of loads in the cabinet and we will calculate the current and suggest a Schneider series without paying for spare watts.
