LRS-75 Enclosed AC/DC Switching Power Supply

Description:

LRS-75 is a 75W single-output enclosed type power supply with 30mm of low profile design.Adopting the full range 85-264VAC input,the entire series provides an output voltage line of 5V,12V,15V,24V,36V and 48V.

In addition to the high efficiency up to 91.5%,the design of metallic mesh case enhances the heat dissipation of LRS-75 that the whole series operates from -30℃ through 70℃ under air convection without a fan.

Delivering an extremely low no load power consumption(less than 0.3W),it allows the end system to easily meet the worldwide energy requirement.LRS-75 has the complete protection functions and 5G anti-vibration capability;it is complied with the international safety regulations such as TUV EN62368-1,EN60335-1,EN61558-1/-2-16,UL62368-1 and GB4943.LRS-75 series serves as a high price-to-performance power supply solution for various industrial applications.

Features:

1. Power and Efficiency: The LRS-75 series delivers a steady 75 watts (W) output power with high-efficiency conversion capabilities, typically achieving higher efficiency than traditional linear power supplies, reducing energy losses and lowering operating temperatures.

2. Wide Input Voltage Range: These power supplies typically have a wide input voltage tolerance, such as 85-264 volts alternating current (VAC), enabling them to operate reliably across various grid voltages worldwide without the need for additional voltage adjustment equipment.

3. Constant Voltage Output: Each LRS-75 model provides a single, precise, and stable direct current (DC) voltage output, e.g., the LRS-75-24 offers a 24 VDC output at 3.2 amperes (A), suitable for devices requiring a specific voltage supply.

4. Ultra-slim Design: Repeated mentions of "slim" or "ultra-slim" indicate that the LRS-75 series features a compact form factor, ideal for space-constrained applications and facilitating system integration and internal chassis layout.

5. Industrial-grade Quality: As a SMUN product, the LRS-75 series is built to stringent industrial standards, incorporating robust heat dissipation, overcurrent protection, short-circuit protection, overvoltage protection, and other safety features to ensure reliability and longevity under harsh conditions.

6. Certifications and Compliance: Given SMUN's market positioning, the LRS-75 series switch-mode power supplies are likely compliant with numerous international safety and electromagnetic compatibility (EMC) standards, such as CE, CCC, ensuring global market adaptability and regulatory compliance.

Applications:

1. Security Surveillance Systems:

   The mention of the LRS-75-24 being used for security surveillance power indicates that this type of switch-mode power supply is suitable for powering cameras, DVRs/NVRs, alarm systems, and other security equipment.

2. Industrial Automation:

   Due to its stable output, industrial-grade build quality, and wide input voltage range, the LRS-75 series is applicable to industrial control devices, sensors, actuators, PLCs (Programmable Logic Controllers), and other components in automated production lines.

3. LED Lighting:

   With the LRS-75-48 labeled as a "strip light power supply," it is evident that this series can be used to drive LED lighting systems requiring a constant DC voltage supply, such as LED strips, panel lights, or other fixtures with fixed voltage requirements.

4. Home Appliances & Consumer Electronics:

   Although primarily geared towards industrial applications, the LRS-75 series may also find use in certain high-end or professional-grade home appliances and consumer electronics, providing power to their internal circuits or peripherals.

5. Laboratory Equipment & Instrumentation

   For laboratory equipment, test instruments, medical devices, and other apparatus requiring precise voltage delivery and high stability in their power supply, the LRS-75 series can offer an ideal solution.

In summary, the LRS-75 series switch-mode power supplies, with their efficient, stable, and compact design and industrial-grade quality, are widely employed in diverse sectors such as industrial automation, security monitoring, LED lighting, home appliances, and instrumentation, where a reliable DC power source is needed. The availability of multiple output voltage versions caters to different voltage level requirements of various devices, while their universal input voltage range and comprehensive safety certifications ensure adaptability and compliance across a broad range of application scenarios.
