## Summary description

HiSmart LRS-50-12 is a 12V 4.2A switching power supply designed for LED strips, lighting fixtures and low-voltage devices requiring a stable 12V DC source. The compact unit provides regulated output up to 50W, protection against overload and short circuit (manufacturer features typical for this model), and is suitable for residential and commercial installations where reliable low-voltage power is needed.

## Long description

HiSmart LRS-50-12 is a compact 12V DC switching power supply that delivers up to 50.4W (4.2A) output. Designed for LED strips, lighting fixtures and other low-voltage devices, this ultra-thin 1U profile unit provides regulated 12V output with adjustable range ±10%, convection cooling and built-in protections for short circuit, overload and over-voltage. It operates from 90–264VAC input and is suitable for installations at altitudes up to 5000 meters.
Advantages
The switching design offers high efficiency (around 86%) and low weight in a small enclosure (99 x 82 x 30 mm). The unit features very low no-load consumption (\<0.5W), low leakage current (\<0.75mA at 240VAC) and a long mean time between failures (MBTF min 630000 hours). Passive convection cooling eliminates the need for a fan, reducing noise and maintenance. Protections for short circuit, overload and over-voltage increase the reliability of connected LED loads and other low-voltage equipment.
Suitable for
Powering LED strips and LED modules
Low-voltage lighting fixtures in residential and commercial spaces
Electronics and devices requiring a stable 12V DC source up to 50W

How to use
Install the HiSmart LRS-50-12 in a well-ventilated location allowing free air convection around the unit. Connect the AC input to a supply within 90–264VAC and observe correct polarity on the DC output when wiring LED strips or other 12V devices. If fine adjustment of the DC output is required, use the built-in adjustment within the ±10% range. Ensure the connected load does not exceed 4.2A (50.4W) continuous rating. Follow local electrical codes and switch power off before making connections.
Usage recommendations
For reliable operation, keep the power supply free from dust and avoid enclosing it in tight, unventilated cabinets. Match cable sizes to load current to minimise voltage drop, and ensure total connected power stays within the 50.4W rating. Use in environments within the specified temperature and humidity ranges and observe the 24‑month warranty conditions for service.
