Delta Electronics power supply series: which to choose
Delta Electronics offers one of the most complete industrial power supply lines in our catalog: from cheap enclosed modules of a few tens of watts to three-phase DIN-rail units up to 960 W. They are all switching supplies with a universal input, so the confusion is usually not the technology but which series fits the job. Below is a short breakdown of each series and a table for quick selection.
The rule of thumb is simple: first decide on mounting (DIN rail or panel/enclosed), then voltage (most often 24 V) and the power you need plus a margin, and only then whether you need PFC and three-phase input.
DRL (Lyte) — the basic DIN-rail line
DRL is the working "baseline" for a control cabinet: compact DIN-rail units at 12, 24 and 48 V, 75–480 W, single-phase input. This is the case where you simply need to power a PLC, sensors, relays and intermediate circuits reliably and cheaply, with no extra features. The catalog has 12 models priced at UAH 1,428–6,812. A popular series — genuine Delta products with warranty, shipped from stock.
Choose it when: a standard 24 V cabinet, typical automation, budget matters. Example — DRL-24V240W1EN (24 V, 10 A, 240 W, DIN).
DRP (CliQ) — the flagship with 3-phase versions
DRP is Delta's most versatile series and effectively the flagship: 12/24/48 V, a wide 30–960 W range, DIN mounting, active PFC. The key advantage of DRP is its three-phase versions (the …3BN index, 340–550 V input), which no other series has. If you have a three-phase supply and want to power automation directly from it without a separate transformer, DRP is the right pick. 16 models, UAH 1,036–19,599.
Choose it when: you need PFC, a wide power range in one line, or three-phase input. Example — DRP024V240W3BN (24 V, 10 A, 240 W, DIN, 3-phase).
DRM (CliQ-M) — high-power DIN modules with PFC
DRM is the "heavy artillery" on the DIN rail: 24 V, 120–960 W, single-phase input, built-in active PFC. The series is meant for loaded cabinets where one DIN rail must deliver high 24 V power while behaving correctly toward the grid (PFC is mandatory for high-power units by code). 3 models, UAH 7,003–25,488.
Choose it when: a large 24 V load on a DIN rail and PFC is required. Example — DRM-24V960W1PN (24 V, 40 A, 960 W, DIN, PFC).
PMT — the widest enclosed/panel line
PMT is Delta's largest series by range and the cheapest entry point: 5/12/24/48 V, 35–350 W, in enclosed and panel form factors. This is not a DIN-rail unit but a classic industrial supply for plate mounting or fitting inside equipment. It suits cases where there is no DIN rail or the unit sits inside a machine. 23 models, UAH 714–3,925 — the lowest entry price of any Delta series. A popular series — genuine Delta products with warranty, shipped from stock.
Choose it when: non-DIN mounting, you need a cheap compact unit, including the uncommon 5 V. Example — PMT-24V100W2BA (24 V, 4.17 A, 100 W, enclosed).
PMC — panel units of medium/high power
PMC is a panel-mount series at 12/24/48 V, 35–600 W, single-phase input. In effect it is the "panel" counterpart for a higher power range: when you need more current than PMT delivers but mounting is still on a panel rather than a DIN rail. 7 models, UAH 808–9,808.
Choose it when: panel mounting and power up to 600 W. Example — PMC-24V600W1BA (24 V, 25 A, 600 W, panel).
PMU — special voltages for telecom and battery buffering
PMU is a narrow, specialized series at the uncommon voltages of 13.8 and 27.6 V, 151 W, panel mounting. These voltages are needed in telecom equipment and in buffer (float-charging) supplies for lead-acid batteries, where the rating differs from the usual 12/24 V. 3 models, UAH 2,282–2,435.
Choose it when: you specifically need 13.8 or 27.6 V — telecom, battery float charging.
Delta series selection table
| Series | Voltage | Power | Mounting | Phases | PFC | Choose when |
|---|---|---|---|---|---|---|
| DRL (Lyte) | 12/24/48 V | 75–480 W | DIN | 1 | — | Basic cabinet, budget |
| DRP (CliQ) | 12/24/48 V | 30–960 W | DIN | 1 + 3 | yes | Flagship; three-phase |
| DRM (CliQ-M) | 24 V | 120–960 W | DIN | 1 | yes | High-power 24 V on DIN |
| PMT | 5/12/24/48 V | 35–350 W | enclosed/panel | 1 | — | Cheapest start, non-DIN |
| PMC | 12/24/48 V | 35–600 W | panel | 1 | — | Panel, up to 600 W |
| PMU | 13.8/27.6 V | 151 W | panel | 1 | — | Telecom, battery buffer |
DIN rail or panel: a note on mounting
For a control cabinet with a standard 35 mm DIN rail, pick DRL, DRP or DRM — they clip onto the rail next to breakers and terminals. If there is no rail or the unit goes inside a machine/equipment enclosure, choose the enclosed/panel PMT, PMC or PMU for screw mounting on a plate. PFC and three-phase input "live" in the DIN series: PFC in DRP and DRM, three-phase input only in DRP (the …3BN versions).
Making the final choice
In short: mounting → voltage → power with a 20–30% margin → PFC/phases.
