Suitable for control cabinets and automation systems requiring reliable DIN-mounted power.

## Long description

HiSmart DR-120-48 is a DIN-rail mounted power supply that delivers 48 V DC with a maximum output of 120 W. It is intended for industrial and network equipment and offers a stable 48-volt source for PoE injectors, network switches, routers, controllers and other low-voltage devices. The compact, narrow-profile unit is designed for installation on standard TS-35/7.5 or TS-35/15 DIN rails and is suitable for control cabinets and automation systems requiring reliable DIN-mounted power.
Advantages
The unit combines high efficiency (\>91%), a narrow profile and convection cooling for silent operation without a fan. It provides built-in protections against short circuit, overload and over-voltage, has a wide AC input range (90–264 V) and operates across a wide ambient temperature range (-30 °C to +70 °C). RoHS and CE certifications confirm compliance with common safety and emissions requirements.
Suitable for
Powering PoE injectors and network switches
Supplying routers, controllers and automation modules
DIN-rail installation in control cabinets and industrial enclosures
Applications requiring a stable 48 V DC source up to 120 W
When it may not be suitable
This power supply is not intended for applications that require voltages other than 48 V or power above 120 W. It may also be unsuitable where active fan cooling is required for thermal management or where a fully sealed, IP-rated housing is needed for harsh outdoor exposure.

How to use
Install the HiSmart DR-120-48 on a TS-35 DIN rail inside a suitable enclosure. Connect the AC mains within the specified input range (90–264 V, 47–63 Hz) to the input terminals while observing local electrical codes. Adjust the DC output within the 47–56 V range if fine tuning is required, then connect the 48 V DC output to your PoE injectors, switches or other low-voltage equipment. Ensure proper ventilation around the unit for convection cooling and verify grounding where applicable.
What to consider before purchase
Required output voltage and power — 48 V DC up to 120 W
Space and DIN rail availability in your control cabinet (135 x 121 x 40 mm)
Ambient temperature range where the unit will operate (-30 °C to +70 °C)
Need for IP-rated enclosure if used in dusty or wet environments
Compatibility with connected equipment regarding voltage tolerance and ripple
Usage recommendations
Use the power supply within its specified input and output ranges, allow adequate ventilation for convection cooling, and rely on the built-in protections for typical industrial and network applications. For installations in harsh environments or where higher power is required, select an enclosure or a different model that meets those needs.
