Test conditions and notes9
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1μF & 47μF parallel capacitor.
  3. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
  5. 5. Installation clearances : 40mm on top, 20mm on the bottom, 5mm on the left and right side are recommended when loaded permanently with full power. In case the adjacent device is a heat source, 15mm clearance is recommended.
  6. 6. 3 seconds max., please refer to peak loading curves.
  7. 7. Derating may be needed under low input voltage. Please check the derating curve for more details.
  8. 8. After 30 minutes of burn-in.
  9. 9. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ

Can the SDR-240-24 power a larger 24V PLC and remote I/O cabinet?

Yes, this unit provides 24V output at up to 10A, with a total power rating of 240W, so it suits larger 24V PLC and remote I/O loads than a 120W model. It is built for DIN rail mounting in industrial control panels.

Is the SDR-240-24 a good fit for 24V industrial automation panels with higher current demand?

It is intended for 24V DC control applications that need more headroom, up to 240W and 10A. The 125.2 x 113.5 x 63.0 mm size gives more output capacity while remaining a DIN rail cabinet power supply.

Can I use this model for a 24V building management control enclosure with multiple field controllers?

Yes, when the combined 24V load remains within 10A and 240W. Its 88-264VAC input range also supports installation in panels fed from a wide range of AC input conditions.

Is the SDR-240-24 designed for protected cabinet use in industrial environments?

Yes, it is best suited for use inside control cabinets or enclosures rather than exposed locations. The specified operating temperature is -25°C to +70°C (refer to the derating curve), and the unit is approved to UL508, TÜV BS EN/EN62368-1, AS/NZS 62368.1, BSMI CNS15598-1 and EAC TP TC 004.

How does the SDR-240-24 compare across the SDR family?

On the SDR-240 series spec sheet there are two models: the SDR-240-24 delivers 24V at 10A (adjustable 24-28V), while the SDR-240-48 delivers 48V at 5A (adjustable 48-55V). Both are rated 240W with 150% peak power (360W for 3 seconds), 94% typical efficiency, active PFC, a DC OK relay contact and free air convection cooling.
