The LRS-350 Single-Output Power Supply by LEYU is an industrial-grade power solution engineered for reliability, versatility, and performance in demanding environments. Certified to meet CE standards, this DIN Rail-mountable unit delivers a maximum rated power of 350W, making it ideal for powering critical industrial and commercial equipment.
Designed with global compatibility in mind, the LRS-350 features a switch-selectable AC input range of 90~132VAC / 180~264VAC; when the switch is set to 230VAC, it also supports DC input of 254~370VDC, adapting to diverse power grids worldwide. It covers a wide spectrum of output voltages—including 3.3V, 5V, 12V, 15V, 24V, 36V, and 48V—with corresponding rated currents ranging from 7.3A (for 48V) to 60A (for 3.3V/5V), ensuring compatibility with various devices.
With a compact footprint of 21511530mm (LWH) and a lightweight design of 0.76Kg, the LRS-350 saves valuable space in control cabinets while supporting easy DIN Rail installation. It operates reliably in temperatures from -20~70℃ (refer to the derating curve for extreme conditions) and achieves a maximum efficiency of 89% (for the 48V model), reducing energy waste and heat generation. Every unit undergoes a 100% full-load burn-in test during production, eliminating potential defects and guaranteeing long-term stability for industrial applications.
The LRS-350’s switch-selectable input range (90~132VAC / 180~264VAC) and DC input support (254~370VDC) make it suitable for global deployment. This flexibility eliminates the need for multiple power supplies in world projects, simplifying inventory management and reducing costs.
It can withstand a 300VAC surge input for up to 5 seconds, a critical feature for industrial environments where grid fluctuations or voltage spikes are common. This protection prevents damage to the power supply and connected equipment, minimizing downtime and maintenance expenses.
The LRS-350 integrates four layers of protection:
Short Circuit Protection: Triggers instantly to avoid component failure.
Overload Protection: Activates at 110~140% of rated power to prevent excessive current draw.
Over Voltage Protection: Varies by model (e.g., 28.8~33.6V for the 24V output) to shield sensitive devices from voltage spikes.
Over Temperature Protection: Guards against overheating in high-temperature settings.
All protections use a hiccup mode—the unit pauses operation during faults and automatically resumes once issues are resolved, no manual reset required.
An LED indicator offers real-time visibility of the power supply’s operational status. This allows maintenance teams to quickly identify issues (e.g., power loss or faults), shortening troubleshooting time and improving system uptime.
High-quality components and precision manufacturing ensure the LRS-350 delivers consistent performance over time. Backed by a 2-year warranty, it provides peace of mind for long-term industrial projects, covering defects in materials and workmanship.
The LRS-350 powers PLCs, servo motors, and sensors in manufacturing lines. Its 350W output, wide temperature range, and overload protection ensure uninterrupted operation of automation systems, reducing production halts caused by power issues.
For surveillance setups, the LRS-350’s low ripple and noise (150~200mVp-p) prevent interference with video signals, ensuring clear footage. Its DIN Rail design simplifies centralized power distribution in control cabinets, streamlining wiring for multiple cameras and DVRs.
As an auxiliary power source for solar setups, the LRS-350’s DC input (254~370VDC) matches solar panel outputs, powering MPPT/PWM controllers and inverters. Its high efficiency reduces energy loss, enhancing the overall performance of solar systems.
The LRS-350’s compact size (21511530mm) fits easily in dense control panels, and its multi-voltage output options (e.g., 12V, 24V) support diverse panel components (e.g., displays, relays). This simplifies power configuration and reduces wiring complexity.
