Test conditions and notes6

1. All parameters NOT specially mentioned are measured at normal input (G:24Vdc, L:48Vdc), rated load and 25℃ of ambient temperature.
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. Tolerance : includes set up tolerance, line regulation and load regulation.
4. Derating may be needed under low input voltage. Please check the derating curve for more details.
5. The power supply is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with the EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf )
6. 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 I use the DDR-60L-15 to power 15V industrial sensors from a 48V DC distribution bus?

Yes. The DDR-60L-15 accepts 18-75V DC input, which covers standard 48V buses. It outputs 15V at up to 4A (60W), making it well suited for powering arrays of 15V industrial sensors, transducers, or measurement instruments mounted on DIN rail in control panels.

Is the DDR-60L-15 suitable for providing isolated 15V power to analog signal-conditioning boards in a process control system?

Yes. Its 4KVdc input-to-output isolation separates the 48V or 24V source bus from the 15V analog circuitry, and ripple and noise are 75mVp-p max. At 60W and 4A it has headroom for multiple signal-conditioning modules that typically draw a few hundred milliamps each.

Can the DDR-60L-15 convert a 24V battery bank to 15V for laboratory bench instruments?

Yes, provided the battery voltage stays within the 18-75V input range. A 24V lead-acid bank typically sits between 20V and 29V, which is well within spec. The DDR-60L-15 delivers a stable 15V at up to 4A, suitable for test instruments, data loggers, or bench-top devices in mobile labs.

Will the DDR-60L-15 function in a high-temperature rooftop telecom enclosure during summer?

Yes, within limits. Its operating range is -40°C to +85°C ambient, but output must be derated at higher temperatures according to the datasheet's derating curve. Check your load against that curve and ensure the enclosure does not exceed the rated temperature under direct solar load.

Can the DDR-60L-15 handle sub-zero temperatures in an unheated utility cabinet?

Yes. The operating temperature range extends down to -40°C, so it will start and regulate properly even in extreme winter conditions. Keep humidity within the rated 5-95% RH non-condensing range.

How does the DDR-60L-15 compare to the DDR-60G-15 in terms of input voltage range?

Both output 15V at 4A (60W) and share identical dimensions of 90.0 x 54.5 x 52.5 mm. The key difference is input range: the DDR-60G-15 accepts 9-36V DC (suited for 12V or 24V source buses), while the DDR-60L-15 accepts 18-75V DC (suited for 24V or 48V source buses). Choose based on your upstream DC voltage.
