The MEAN WELL DDR-15G-5 is a 15W isolated DC-DC converter in the DDR-15 series, designed for DIN rail mounting in industrial enclosures. It accepts a wide 9 to 36VDC input (4:1 range) and delivers a regulated 5VDC output at up to 3A, with 4000VDC input-to-output isolation. At only 17.5mm wide (1SU), it supports space-efficient panel layouts and operates across a -40 to +85°C temperature range using free air convection cooling - no fan required.
Key Features and Benefits
Ultra-slim 17.5mm (1SU) width - Supports space-saving installation in densely populated DIN rail panels and control cabinets.
4:1 wide input range (9 to 36VDC) - Helps the converter operate across 12V and 24V nominal DC bus systems without requiring separate models.
4000VDC input-to-output isolation - Provides galvanic separation between input and output circuits, supporting noise reduction and safety in industrial installations when used within the manufacturer's stated limits.
Free air convection cooling - Eliminates the need for a fan, reducing acoustic noise and mechanical complexity in the installation.
-40 to +85°C operating temperature range - Supports deployment in demanding industrial environments, including cold storage and high-ambient enclosures, within the manufacturer's stated limits.
Output voltage adjustable ±10% - Allows fine-tuning of the 5VDC output to meet the exact requirements of connected loads.
No minimum load required - Supports reliable operation even when connected loads are light or intermittent.
Compatible with DIN rail TS-35/7.5 and TS-35/15 - Fits standard DIN rail profiles commonly used in industrial control panels, simplifying integration.
Built-in protections: short circuit, overload, over voltage, input reverse polarity, and input under voltage - Helps protect the converter and connected equipment under abnormal operating conditions, within the manufacturer's stated limits.
Screw terminal block connections (4 pins) - Supports secure, tool-accessible wiring for both input and output in panel environments.

Customer Questions
What DIN rail profiles is the DDR-15G-5 compatible with?
The DDR-15G-5 is designed to mount on standard DIN rail profiles TS-35/7.5 and TS-35/15, which are commonly used in industrial control panels.
Does this converter require a minimum load to operate correctly?
No. The DDR-15G-5 does not require a minimum load, so it can operate reliably even when connected loads are light or intermittent.
Can the output voltage be adjusted?
Yes. The 5VDC output is adjustable within ±10% of the nominal value, allowing fine-tuning to match the requirements of connected equipment.
Does the DDR-15G-5 work with both 12V and 24V DC bus systems?
Yes. The 4:1 wide input range of 9 to 36VDC supports both 12V and 24V nominal DC bus systems without requiring separate converter models.
Does this converter require a fan or forced-air cooling?
No. The DDR-15G-5 uses free air convection cooling and does not require a fan or forced-air system.
Customer Concerns
Will the 17.5mm width actually fit in my existing panel without displacing other components?
At 17.5mm (0.688 inches) wide - equivalent to 1 space unit (1SU) on a standard DIN rail - the DDR-15G-5 is among the slimmest converters in its power class. Verify available rail space and adjacent component clearances against the published dimensions (3.54 inches L x 0.688 inches W x 2.30 inches H) before installation.
Is the 4000VDC isolation rating sufficient for my industrial application?
The DDR-15G-5 is rated for 4000VDC input-to-output isolation. Whether this meets the requirements of your specific application or system standard should be confirmed against your equipment's compliance documentation and any applicable installation codes.
Can this converter handle the full 3A output continuously at high ambient temperatures?
The DDR-15G-5 is rated for operation from -40 to +85°C. Consult the manufacturer's datasheet for any derating curves that may apply at elevated temperatures before relying on full rated output current in high-ambient installations.
