Cooling is by free air convection with no fan required, and the unit carries agency approvals listed by Jameco as UL, CUL, TUV, CB, CE, EN, and EAC. A 3-year manufacturer warranty is included.
Key Features and Benefits
Ultra slim 17.5mm (1SU) step-shape housing - Helps conserve valuable DIN rail space in compact control panels and enclosures.
Universal input 85 to 264 VAC with 277 VAC operational input support - Supports a broad range of global and North American supply voltages, reducing the need for separate SKUs across installations.
DC output voltage adjustable - Allows fine-tuning of the 12V output to meet the precise voltage requirements of connected equipment.
Built-in short circuit, overload, and over voltage protections - Helps safeguard connected equipment within the manufacturer's stated limits.
Cooling by free air convection - Eliminates the need for a fan, supporting quieter operation and reducing mechanical wear in the cooling path.
Isolation class II - Supports installations where a protective earth connection may not be available, per the manufacturer's stated design.
Passes LPS (Limited Power Source) classification - Supports use in systems where LPS-rated power sources are required by the equipment design or applicable standards.
No-load power consumption <0.3W - Helps reduce standby energy draw when the load is disconnected.
LED power-on indicator - Provides a quick visual confirmation that the unit is energized during installation and troubleshooting.
DIN rail TS-35/7.5 or TS-35/15 mountable with screw terminal block output - Supports straightforward installation on standard DIN rails and simplifies field wiring.
Agency approvals listed by Jameco: UL, CUL, TUV, CB, CE, EN, EAC - Supports compliance documentation requirements for industrial and commercial installations.
3-year manufacturer warranty - Provides documented coverage for the product over an extended service period.

Customer Questions
What DIN rail types is the HDR-15-12 compatible with?
The HDR-15-12 is designed to mount on DIN rail types TS-35/7.5 and TS-35/15. Verify that your enclosure uses one of these standard rail profiles before installation.
Does the HDR-15-12 require a fan for cooling?
No. The unit is cooled entirely by free air convection with no fan required. Adequate airflow around the unit should be maintained per the datasheet to support operation within the rated -30 to +70°C temperature range.
Can the output voltage be adjusted?
Yes. The DC output voltage is adjustable, allowing fine-tuning from the nominal 12V output. Refer to the manufacturer datasheet for the adjustment range and procedure.
Is the HDR-15-12 suitable for 277 VAC input systems?
The unit supports a universal input range of 85 to 264 VAC and also supports 277 VAC operational input, as noted on multiple product listings. Confirm input voltage compatibility with the manufacturer datasheet before installation.
What protections are built into the HDR-15-12?
The HDR-15-12 includes short circuit, overload, and over voltage protections, which help safeguard connected equipment within the manufacturer's stated limits.
Customer Concerns
The 15W output seems low - will this supply enough power for my application?
The HDR-15-12 is rated at 15W maximum continuous output (12VDC at 1.25A). Before selecting this unit, confirm that your total load current does not exceed 1.25A and total wattage does not exceed 15W. For higher-load applications, MEAN WELL offers other HDR series models with greater output capacity.
I need a power supply that qualifies as a Limited Power Source (LPS) for my equipment design.
The HDR-15-12 passes LPS (Limited Power Source) classification. Verify that this meets the specific LPS requirements of your equipment or applicable standards before finalizing your design.
I am concerned about operating this unit in a high-temperature industrial environment.
The HDR-15-12 is rated for operation from -30 to +70°C using free air convection cooling. Ensure adequate airflow clearance around the unit in your enclosure and consult the manufacturer datasheet for any derating guidance at elevated temperatures.
