Mean Well LRS Series Single‑Output Switching Power Supplies
- The Mean Well LRS series delivers compact, reliable single‑output DC power in a ventilated metal housing. Available across commonly used power classes (50W, 75W, 150W, 200W), the LRS family is designed for industrial and commercial applications needing a small-footprint, convection‑cooled supply with proven protection and international safety approvals.
Key benefits
- Compact, low‑profile metal case with honeycomb ventilation for excellent heat dissipation without a fan (quiet, maintenance‑free).
- Wide selection of fixed output voltages (3.3V, 5V, 12V, 15V, 24V, 36V, 48V) and power ratings to match a broad range of loads.
- High efficiency (typical 86%–91% depending on model and load) to reduce operating heat and energy costs.
- Robust protection suite: short‑circuit, overload, over‑voltage and over‑temperature protection for safe, trouble‑free operation.
- Universal AC input (wide input range) with low leakage current and good hold‑up time for stable performance.
- Multiple international safety and EMC approvals for global deployment (factory‑tested and certified).
Typical specifications (summary)
- Power classes: 50 W (LRS‑50), 75 W (LRS‑75), 150 W (LRS‑150), 200 W (LRS‑200).
- Output voltages: common offerings include 3.3V, 5V, 12V, 15V, 24V, 36V, 48V.
- Input: wide AC input (typically 85–264 VAC); many models support DC input ranges as well.
- Cooling: convection cooled (no fan).
- Protections: Overload (Hiccup/constant-current limit depending on model), short-circuit auto-recovery, over-voltage protection, over-temperature shut-down/recovery.
- Form factor: screw terminal block, metal ventilated case for easy mounting and installation.
Applications
- Industrial automation and control systems
- LED signage and lighting drivers
- Security and surveillance equipment
- Network/telecom devices and edge electronics
- Laboratory and test systems
- Embedded systems and machine control
Why choose Mean Well LRS
- Proven reliability from a widely used commercial power supply family.
- Broad model choice makes it easy to pick the correct wattage and voltage for your project.
- Compact, fanless design reduces noise and maintenance while maintaining thermal performance.
- Safety certifications and stable electrical performance simplify system approvals and integration.
Ordering & selection tips
- Choose the LRS series model by required continuous wattage and output voltage (e.g., LRS‑75‑12 for 75W at 12V).
- Confirm input requirements for your region (universal AC vs. switchable ranges or DC input options).
- If the load is inductive or has inrush (motors, capacitive loads), allow headroom above rated current to ensure reliable operation.
- For battery backup or critical systems, check hold‑up time and consider upstream surge suppression.
