Power supply HiSmart DR-75-12 12V 6.3A switching power supply

HiSmart DR-75-12 is a compact DIN-rail switching power supply that provides a regulated 12V DC output with a rated current of 6.3A and rated power of 76W. The unit accepts a wide AC input range and is cooled by free air convection, making it suitable for installation in control cabinets and electrical enclosures where a small, efficient power source is required.

Advantages

The switching design delivers stable output with an adjustable DC voltage range of -9% to +10% and low ripple and noise (100 mV p-p). It includes protections against short circuit, overload and over-voltage, features low leakage current (<1 mA at 240V AC), and offers a compact, lightweight construction that mounts on TS-35/7.5 or TS-35/15 DIN rails.

Suitable for

• CCTV cameras and surveillance systems
• LED strips and lighting modules
• Routers, modems and small network devices
• Industrial control modules and low-voltage electronics

How to use

Mount the HiSmart DR-75-12 on a compatible DIN rail (TS-35/7.5 or TS-35/15) inside a suitable enclosure. Connect the AC input to a mains supply within 90–264 V and observe correct grounding and wiring practices. Adjust the DC output within the specified -9%/+10% range if fine tuning is required, and connect the 12V DC output to the load while ensuring the total current draw does not exceed 6.3 A. Allow natural convection around the unit for cooling and avoid obstructing airflow.

Usage recommendations

Install the power supply in a dry, ventilated location with ambient temperature between -20 °C and +60 °C. Verify wiring polarity and secure connections before powering on. For long-term reliability, keep the ambient humidity within 20%–90% RH and avoid exposure to corrosive atmospheres or excessive vibration.
