Product Description :
The MEAN WELL LRS-350-12 Power Supply is a 350W single-output enclosed switching power supply, delivering a stable 12V DC at 29A. Part of the trusted LRS-350 series, it is one of the most popular 12V power supplies for industrial, automation, and electronics applications.
Designed with a low-profile 30mm enclosure, this power supply combines high efficiency (up to 89%), low power consumption (<0.75W at no load), and full protection features including short-circuit, overload, over-voltage, and over-temperature safeguards. It is equipped with a long-life cooling fan with intelligent ON/OFF control, ensuring stable operation under demanding conditions.
The LRS-350-12 operates under a wide input voltage range of 90–132VAC or 180–264VAC (selectable by switch) and withstands surges up to 300VAC for 5 seconds. With full load capability, it can operate reliably in temperatures from -25°C to +70°C and at altitudes up to 5000 meters, making it suitable for global deployment.
Compliant with IEC/UL 62368-1 safety standards, tested with 5G vibration resistance, and subjected to a 100% full load burn-in test, this MEAN WELL power supply ensures long-lasting performance, high reliability, and safety.
