Schneider Electric ABL8RPS24030 Phaseo 24 V 3 A Power Supply

ABL8RPS24030: Phaseo regulated switch mode supply, 24 V DC 3 A

The ABL8RPS24030 is the smallest member of the Phaseo universal range in this set: a 45 mm wide DIN rail unit that takes single-phase supplies from 100 V up to 500 V. It is a regulated switch mode power supply in Schneider Electric’s Modicon Power Supply (Phaseo) offer, giving 24 V DC at 3 A, equal to 72 W. A 45 mm wide unit like this is the standard answer for a 24 V rail in a compact control cabinet where every millimetre of DIN rail counts. Seven Star LLC supplies the ABL8RPS24030 in Oman and the GCC as an independent supplier based in Muscat.

Reading the reference: ABL8 is the Phaseo prefix, the letters RPS identify the model line, 24 the output voltage, and the final digits (030) correspond to the rated output current in tenths of an amp (here 3 A). This is our reading of the pattern and the datasheet remains the reference for ordering.

Selection checklist for the ABL8RPS24030

• Sum the 24 V load below 3 A and decide how much margin the hottest cabinet needs.
• Match the mains: 100–120 V AC single phase / 200–500 V AC phase to phase; limits 170–550 V AC and 85–132 V AC.
• Check the footprint of 45 × 125 × 125 mm and the vertical mounting rule.
• Decide whether a diagnostic relay is needed and whether two units must run redundantly through a separate redundancy module.
• State the highest ambient temperature so derating can be assessed.

ABL8RPS24030 technical data

Where the ABL8RPS24030 fits in Oman and the GCC

This unit is suited to small control cabinets for pump starters, valve controllers and instrument panels where a single 3 A rail is enough. The wide input window of Phaseo supplies is practical in the region because industrial plants mix 230 V, 400 V and sometimes 415 V sources, and imported machines arrive with their own voltage assumptions. High ambient temperatures are the main design consideration: the unit is rated for 50 °C without derating, so cabinets in direct sun, desalination plant rooms or switch rooms without air conditioning should be checked against that value, with ventilation or sunshields where needed.

Supplying the ABL8RPS24030: input bands, inrush and filtering

The datasheet lists the nominal input as 100–120 V AC single phase, terminal(s): N-L1; 200–500 V AC phase to phase, terminal(s): L1-L2, with accepted limits of 170–550 V AC and 85–132 V AC. The 100–500 V coverage is the headline of this line: one stock reference can serve 110 V, 230 V, 400 V and 480 V panels. The inrush current is 30 A and efficiency is 87 %, which leaves 7.8 W of heat inside the housing at full load.

A power factor correction filter conforming to IEC 61000-3-2 is listed as provided equipment, together with an anti-harmonic filter for low-frequency harmonic currents; the quoted power factor is 0.51 at 240 V AC and 0.59 at 120 V AC. Terminals are screw type: 3 × 0.5–3 × 4 mm² (22–12 AWG) for the input, and 4 × 0.5–4 × 4 mm² (22–12 AWG) for the output.

Mounting and cooling the ABL8RPS24030

The unit measures 45 × 125 × 125 mm and weighs 0.3 kg. It clips onto a 35 × 7.5 mm or 35 × 15 mm DIN rail and must be mounted vertically. The nominal ambient temperature for the universal Phaseo supplies is 50 °C, with derating up to a maximum of 60 °C; the datasheet text for this reference reads 50–60 °C with derating factor mounting position A < 2000 m and −25–50 °C without derating mounting position A < 2000 m. Protection is IP20, so the unit belongs inside an enclosure, and the altitude limit is 2000 m.

Two LEDs report status: one (green and red) for output voltage and one (green, red and orange) for output current. No diagnostic relay terminal is listed for this size, so monitoring has to rely on the LEDs or on a downstream voltage monitor. Dielectric strength is 3500 V between input and ground, 4000 V between input and output, 500 V between output and ground.

Phaseo universal range around the ABL8RPS24030

Within this set the references step up in power: ABL8RPS24030 (72 W), ABL8RPS24050 (120 W), ABL8RPM24200 (480 W) and the three-phase ABL8WPS24400 (960 W). The datasheet allows series or parallel connection of at most two units, only recommended for identical references; for better availability supplies can instead be paralleled through the ABL8RED24400 redundancy module.

Output, boost and protection of the ABL8RPS24030

The output is 24 V DC and can be trimmed over 24–28.8 V, which helps compensate cable drop on long runs. For short overloads the unit supplies a temporary boost of 1.5 times the nominal current for 4 seconds, useful for inrush of solenoid valves and contactors. At the nominal figure the ABL8RPS24030 supplies 3 A; a planning load of 80 % is about 2.4 A.

Protections listed are overload and short-circuit with manual or automatic reset, overvoltage at 30–32 V with manual reset, undervoltage tripping when the output falls below 21.6 V, and thermal protection with automatic reset. The datasheet notes that derating should be considered in extreme conditions: intensive operation near nominal current at high temperature, an output set above 24 V, or parallel connection to increase total power.
