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-30G-5 to power a 5V microcontroller or single-board computer from a 24V DC bus?

Yes. The DDR-30G-5 accepts 9-36V DC input and outputs 5V at up to 6A (30W), so a 24V bus is well within range. It provides enough current for Raspberry Pi-class SBCs, Arduino-based controllers, or custom microcontroller boards with attached peripherals in DIN rail-mounted automation panels.

Is the DDR-30G-5 suitable for providing isolated 5V power to USB-powered devices in an industrial cabinet?

Yes. The 4KVdc I/O isolation protects 5V USB devices from noise and transients on the DC bus. At 6A output, the DDR-30G-5 can supply multiple USB peripherals such as barcode scanners, touchscreens, or HID interfaces as long as total draw stays under 30W.

Can the DDR-30G-5 power 5V logic circuits in a vehicle or mobile equipment application?

Yes, as long as the vehicle supply stays within the 9-36V DC input range, which covers nominal 12V and 24V systems. The under-voltage lockout switches the unit off at 8.5V or below (on again at 9V or above), and derating may be needed at low input voltage. Within range it delivers a stable 5V at up to 6A for onboard data loggers, display screens, or communication interfaces in trucks, forklifts, or marine vessels.

Does the DDR-30G-5 require active cooling or ventilation?

The spec sheet lists no fan or forced-air cooling requirement for the DDR-30G-5. It is rated for a working temperature of -40°C to +85°C, but full 30W output is not available across that whole range: load must be derated at higher ambient temperatures according to the derating curve, so make sure the air inside the cabinet stays within those limits.

Can I use the DDR-30G-5 to power LED indicator panels or small display modules from a 12V solar battery?

Yes. A 12V solar battery (typical range 10-14.4V) is within the 9-36V input window, though the sheet notes that derating may be needed at low input voltage, so check the output-vs-input derating curve. The DDR-30G-5 provides 5V at up to 6A, which is sufficient for small LED matrix panels, OLED displays, or status indicator arrays in solar-powered kiosks or remote monitoring stations.
