More Information

Overview Manuals Input Paths Output Control Protection Modes Fan Control

Features:

  • Accepts a wide AC range or high-voltage DC input without a manual range selector.
  • Provides a regulated 24 V DC, 10 A output with front-panel voltage adjustment.
  • Controls its built-in cooling fan according to the internal temperature threshold.
The enclosed chassis combines the rectifier, PFC stage, isolated converter and cooling assembly in one supply.

Input energy is conditioned before the regulated output stage feeds the 24 V load through the DC terminals.

Fault circuits separate overload recovery from the restart behavior required after an output overvoltage event.

The MEAN WELL SP-240-24 24V Switching Power Supply may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Input conversion choices

  • AC source: The universal input accepts 88–264 V AC across the specified line-frequency range.
  • DC source: A 124–370 V DC bus may feed the same input section within the documented limits.
  • PFC stage: Power-factor correction operates ahead of the isolated converter when AC is applied.
  • Power indicator: The front LED identifies an energized output after the conversion stages start.

Regulated 24 V delivery

  • Nominal rail: The supply is rated for 24 V DC at up to 10 A.
  • Adjustment window: The output control permits a 20–28 V setting range.
  • Load boundary: Combined voltage and current must remain inside the 240 W rating.
  • Dynamic hold-up: The stored-energy stage maintains the output for the documented hold-up interval after input loss.

Fault-response sequence

  • Overload: Hiccup operation limits sustained stress and restarts after the load fault clears.
  • Overvoltage: The output shuts down at the protection threshold and input power must be reapplied.
  • Overtemperature: The converter stops during excessive temperature and resumes after cooling.
  • Short circuit: The built-in protection network limits the effect of an output short circuit.

Thermal operating plan

  • Forced air: A built-in DC fan moves cooling air through the enclosed supply.
  • Start threshold: The fan normally switches on when the monitored temperature reaches 40 °C.
  • Stop threshold: Fan operation normally stops after the monitored point falls to 35 °C.
  • Ambient derating: Available load follows the published curve across the -20 to 70 °C operating range.
Description
MEAN WELL SP-240-24 is a 240 W enclosed single-output switching power supply in the SP-240 series, converting a wide AC or high-voltage DC source into a regulated 24 V DC rail for powered equipment.

At its DC output, SP-240-24 supplies up to 10 A and allows the nominal rail to be adjusted from 20 to 28 V. Line and load regulation hold the selected output within the documented limits as input voltage and connected load change.

The input stage accepts 88–264 V AC or 124–370 V DC. Built-in power-factor correction conditions the AC input before energy passes through the isolated conversion stage, while the power-on indicator reports that the output is energized.

Protection circuits in SP-240-24 respond separately to overload, output overvoltage and excessive temperature. A built-in DC fan provides forced-air cooling and switches according to internal temperature, so enclosure ventilation and the published load-derating curve remain part of installation planning.

Technical notes
MEAN WELL SP-240-24 delivers 24 V DC at 10 A from an 88–264 V AC or 124–370 V DC input, with PFC and temperature-controlled forced-air cooling.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can MEAN WELL SP-240-24 run from either an AC source or a high-voltage DC bus?
Yes. MEAN WELL SP-240-24 accepts 88–264 V AC at 47–63 Hz or 124–370 V DC, so the selected source must stay inside the documented input range.
When the output is adjusted, what load limit still applies to MEAN WELL SP-240-24?
MEAN WELL SP-240-24 permits 20–28 V adjustment, but its rated output remains 240 W with a 10 A maximum current; both limits must be respected.
What happens after an overload is connected to MEAN WELL SP-240-24?
An overload of 105–135% makes MEAN WELL SP-240-24 enter hiccup protection, and normal output returns automatically after the overload condition is removed.
Why might the cooling fan on MEAN WELL SP-240-24 remain stopped after power-up?
The fan in MEAN WELL SP-240-24 is temperature controlled: it typically starts at 40 °C or above and stops at 35 °C or below, so a stopped fan at low temperature can be normal.
Does MEAN WELL SP-240-24 automatically recover from output overvoltage protection?
No. MEAN WELL SP-240-24 shuts its output down at the documented overvoltage threshold and requires the input power to be cycled for recovery.
How should MEAN WELL SP-240-24 be applied near the upper ambient-temperature limit?
Use the published output derating curve for MEAN WELL SP-240-24, maintain ventilation for its forced-air path and keep operation within the -20 to 70 °C range.
