    Technical specifications for the Mean Well SP-240 series single-output power supply with PFC function, sold by TRC Electronics.

    Overview

    The Mean Well SP-240 series is a 240W single-output switching power supply with a universal AC input (full range), built-in active Power Factor Correction (PFC, PF>0.95), and forced-air cooling via a built-in DC fan with on/off control. It's built for reliability with short circuit, overload, over-voltage, and over-temperature protection, and carries a 3-year manufacturer warranty. Available in seven fixed output voltage models from 5V to 48V.

    Features

    • Universal AC input / full range
    • Built-in active PFC function, PF>0.95
    • Protections: short circuit / overload / over voltage / over temperature
    • Forced air cooling by built-in DC fan
    • Built-in fan ON/OFF control
    • LED indicator for power on
    • Fixed switching frequency at 90KHz
    • 3-year warranty

    • Hold-up time (typ.): 20ms @ 230VAC / 20ms @ 115VAC at full load

    Input Specifications

    Attribute Value
    Voltage range 88 ~ 264VAC / 124 ~ 370VDC
    Frequency range 47 ~ 63Hz
    Power factor (typ.) PF>0.95 @ 230VAC; PF>0.98 @ 115VAC at full load
    Efficiency (typ.) 79% (5V model) up to 89% (48V model)
    Inrush current (typ.) 25A @ 115VAC / 40A @ 230VAC

    Notes

    • All parameters not otherwise specified are measured at 230VAC input, rated load, and 25°C ambient.
    • The power supply is a component intended for installation into a final equipment enclosure; the final equipment must be re-confirmed against EMC directives.
    • Derating may be needed under low input voltages — refer to the derating curve.
