Meanwell Make Switch Mode Power Supply (SMPS)

Meanwell Make Switch Mode Power Supply (SMPS) About

• Enclosed Type (LRS/SE Series): Known for low-profile design (30-41mm), high efficiency (up to 90%), and 3-year warranties.
• DIN Rail Type (XDR-E/MDR Series): Ideal for industrial control cabinets, supporting up to 960W with high efficiency (up to 96%).
• High Power (RSP/RST Series): Offers 500W to 15KW with programmable voltage/current and parallel functionality.
• Safety Protections: Most models include short circuit, overload, over voltage, and over-temperature protections.

• Industrial Automation: Machinery, control systems.
• Lighting: LED signage and displays.
• Electronics: Communication equipment and IT applications. 

• Input: 85-264VAC (universal range).
• Output: Available in common voltages like 5V, 12V, 24V, 36V, 48V.
• Cooling: Free air convection or built-in DC fan. 
• A Mean Well power supply with a 24 VDC / 5A output is rated at 120W. The most common models for these specifications are available in DIN rail, enclosed (chassis mount), and desktop adapter formats. 1. DIN Rail Series:  EDR-120-24 / NDR-120-24 These are standard for industrial control cabinets and automated machinery.
  • Output Current: 5A (Rated).
  • Input Voltage: 90264 VAC (Universal).
  • Efficiency: 87.5% 88%.
  • Protections: Short circuit, overload, overvoltage, and overtemperature.
  • Dimensions: 40mm width (Slim design).
  • Mounting: Fits TS-35/7.5 or TS-35/15 DIN rails
  • 2. Enclosed Type: LRS-150-24 Though rated for up to 6.5A, it is frequently used for 5A applications due to its cost-efficiency and low profile. 
    • Output: 24V / 6.5A (Can easily handle a 5A load).
    • Input: 85132 VAC / 170264 VAC (Selectable by switch).
    • Form Factor: 1U low profile (30mm height).
    • Cooling: Free air convection.
    • Vibration: Withstands 5G vibration tests
    • A 24 VDC SMPS is defined by several key technical specifications that determine its performance, safety, and compatibility with your equipment. Core Electrical SpecificationsThese parameters define the primary input and output capabilities of the power supply:
      • Input Voltage Range: Most 24V SMPS are "Universal Input," accepting 100V to 240V AC (10%) at 50/60Hz. Some industrial models also accept DC input, typically between 127V and 370V DC.
      • Output Voltage Adjustment: Many units allow you to fine-tune the voltage, usually within a range of 21.6V to 28.8V DC (10-20%) using a built-in potentiometer.
      • Efficiency: Modern units typically operate at 85% to 94% efficiency. Higher efficiency reduces heat generation and electricity costs.
      • Ripple & Noise: This measures the "cleanliness" of the DC power. Industrial standards usually keep this below 150mVp-p or less than 1% of the output voltage to prevent interference with sensitive electronics. 
      Protection ParametersReliable SMPS units include standard safety features to protect both the power supply and the connected load:
