Test conditions and notes6
- 1. All parameters NOT specially mentioned are measured at 24VDC input, 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-15G-5 to power a 5V embedded controller from a 12V or 24V DC bus?
Yes. The DDR-15G-5 accepts 9-36V DC input and outputs a regulated 5V at up to 3A (15W). It is well suited for powering embedded controllers, single-board computers, or microcontroller-based modules from a 12V or 24V battery or DC distribution bus.
Is the DDR-15G-5 suitable for powering small HMI displays in industrial automation panels?
Yes. With 15W at 5V/3A, the DDR-15G-5 can power small 5V HMI touch panels or operator interfaces inside control cabinets. Its 4KVdc input-to-output isolation separates the display electronics from the DC bus.
Can this converter power 5V sensors or I/O modules in a DIN rail enclosure fed by a solar battery system?
The DDR-15G-5 accepts input from 9V to 36V DC, which covers common 12V and 24V battery voltages used in solar installations. It can supply 5V at up to 3A for sensors, data loggers, or I/O modules in off-grid setups; derating may be needed at low input voltage.
Will the DDR-15G-5 work in an unheated outdoor enclosure in cold climates?
The DDR-15G-5 is rated for an operating temperature range of -40°C to +85°C (with derating per the derating curve), so it can function in extreme cold and hot environments. Its humidity rating is 5-95% RH non-condensing, so it must be installed inside a weatherproof cabinet or enclosure to protect it from moisture and dust.
How does the DDR-15G-5 compare to other models in the DDR-15 series?
The DDR-15G sub-series (9-36V input) is available in 3.3V/3.5A, 5V/3A, 12V/1.25A, 15V/1A, and 24V/0.63A output variants. The DDR-15L sub-series covers the same output voltages but accepts a higher 18-75V DC input range. All share the same 17.5 x 90 x 54.5 mm housing.
Can I use the DDR-15G-5 to step down a vehicle 24V DC system to 5V for USB charging or diagnostic equipment?
Yes. The 9-36V input range covers standard 24V vehicle electrical systems. The DDR-15G-5 provides a stable 5V/3A output suitable for powering USB-based diagnostic tools, GPS trackers, or small onboard instruments in trucks, buses, or heavy equipment.
