Introduction
Systems must be reliable, efficient, and built to last in industrial automation. The LRS-350 Switching Power Supply from Leyu Electric meets all these needs. It is small but mighty and works well in many uses, such as LED lighting and programmable logic controllers (PLCs). Let's look at why the LRS-350 is a key part of today's automation setups.
High Power, Compact Design
The LRS-350 is small (215×115×30 mm) but gives strong power with a 350-watt single output. It comes in different voltage levels, from 3.3V to 48V, so that it can be used in many systems. It also works with 115V and 230V input, making it easy to use in different countries and industrial setups.
Key Specs:
- Output Power: 350W
- Voltage Options: 3.3V to 48V
- Size: 215 × 115 × 30 mm
- Weight: About 1.1 kg
Johnson Box:
Small size. Big power.
The LRS-350's compact design easily fits into tight control cabinets while delivering strong and reliable performance.
Rugged Performance in Harsh Conditions
Industrial settings can be strict, with sudden power and electrical noise changes. The LRS-350 is made to handle these challenges. It can take a 300VAC power surge for up to 5 seconds without damage. It also includes strong safety features to protect your system, such as:
- Short Circuit Protection
- Overload Protection
- Over Voltage Protection
- Over Temperature Protection
Its natural air cooling design means fewer mechanical failures and less maintenance over time, which makes it ideal for 24/7 operations.
Key Takeaway: LRS-350 keeps systems running with built-in failsafe mechanisms when failure is not an option.
Exceptional Efficiency & Stability
Efficiency directly affects energy costs and operational heat. The LRS-350 achieves over 88% efficiency, minimizing energy loss and maximizing system uptime. It features low ripple and noise, ensuring stable output—crucial for sensitive electronics.
- Ripple: <150mVp-p
- Tolerance: ±1% to 4%
- Inrush Current: 60A max (115VAC)
Helpful Info: Stable power = longer equipment life. Use the LRS-350 to prolong the lifespan of your entire system.
Built for Longevity & Compliance
Each LRS-350 is manufactured with high-grade materials and undergoes a 100% full-load burn-in test to ensure reliability. With a 2-year manufacturer warranty, users have peace of mind knowing they're investing in a quality product.
Certifications:
