Lovato PSL124024 24 V DC 10 A 240 W DIN Rail Power Supply

PSL124024 switching power supply: decoded part number

The PSL124024 is a single-phase DIN-rail switching power supply from Lovato Electric that converts mains or DC input into a regulated 24 V DC output at up to 10 A (240 W). It powers PLCs, relays, sensors and control circuits in panels and is built in a metal housing with a wide temperature range.

Decoded: PSL1 is the single-phase switching power supply family, and the ordering code PSL124024 identifies the model with a 24 V DC output, 10 A and 240 W in the catalogue.

Technical specifications of the PSL124024

Values are from the Lovato Electric catalogue entry for PSL124024. Confirm wiring and mounting clearances in the manual before commissioning.

How the PSL124024 works

A switching power supply rectifies the input, chops it at high frequency through a transformer and regulates the output with feedback. The result is a stable 24 V DC supply with low ripple. The internal fuse protects the input, and overload and short-circuit protection protect the load: the fold-forward characteristic allows heavy loads, such as motors or capacitive inputs, to start while limiting energy in a true short circuit.

The output voltage can be fine-tuned with a potentiometer between 22.5 and 28.5 V, which helps compensate voltage drop on long cables. Three LEDs indicate power on, low output voltage and power ready, and the unit has a Power Ready indication.

Up to three units can be connected in parallel for capacity increase according to the catalogue.

Fit in the system and related Lovato Electric parts

The PSL1 range provides a series of DIN-rail supplies; in a control panel it sits on the incoming supply side and feeds distribution blocks, PLC racks and relay modules.

• Surge protectors and fuse holders from the Lovato Electric range
• Battery chargers for DC systems
• Micro PLCs of the LRD and LRK families

Selection and ordering checklist for the PSL124024

Before ordering the PSL124024, settle the following points so that the right variant is quoted:

• Total load current of 24 V circuits including inrush, with 20 to 30 % reserve
• Input supply voltage: 115 to 230 V AC or DC
• Ambient temperature in the cabinet; derating above +60 °C
• Need for redundancy or parallel operation
• Mounting space: 83.5 mm width on a 35 mm DIN rail

Installation, commissioning and maintenance of the PSL124024

Mount on a 35 mm DIN rail with free space above and below for convection. Connect input L and N and protective earth, then connect the output to the load distribution. Adjust the output voltage under load with a meter.

Before connecting sensitive loads, check the output voltage and the status LEDs.

• Check the LED status in routine rounds
• Keep the vents clean of dust
• Replace the unit after long service in hot cabinets
• Tighten terminals annually

Typical applications in Oman and the GCC

A 240 W supply covers typical PLC and instrument panels, small valve actuators and control relays in plants across the Gulf. The wide temperature range up to +71 °C is a benefit in cabinets in unconditioned rooms and in kiosks heated by the sun.

When the supply feeds safety-relevant or process-critical loads, consider redundancy with two units and a decoupling module, or a battery backup, instead of relying on one supply.

To size the supply, add up the current of every 24 V consumer in the panel, include the inrush of relay banks and contactor coils, and keep a reserve of roughly one fifth of the rating so the unit does not run at its limit in a hot cabinet. At the stated derating of 2.5 % per degree above +60 °C, a cabinet that regularly reaches +65 °C loses about 12 % of the output rating, which matters for a unit already loaded near 10 A. Provide us with the load list and the ambient figure and we will check the model against them.

Site conditions in Oman for the PSL124024

Electrical rooms and outdoor panels in the Gulf often operate well above the 25 °C reference temperature used in many catalogues. Before you finalise the PSL124024, compare the expected panel temperature with the operating range and any output derating stated in the manufacturer documentation, and leave the recommended clearance above and below the device for convection. Supply quality also varies between sites, so confirm the input voltage range, frequency and any requirements for protection on the supply side.

Where the device feeds or monitors critical loads, plan how faults will be signalled to the control system and how a replacement can be installed quickly. Keeping one spare PSL124024 per site and recording its settings helps maintenance teams in Oman restore service with minimum downtime.
