Power Supply Unit MEAN WELL LRS-35-5

The MEAN WELL LRS-35-5 is a 35W single-output enclosed power supply with a low-profile 30 mm height and a metal mesh case that improves heat dissipation. It accepts a wide AC input range of 85–264 VAC and provides a 5 V DC output. The unit features high efficiency (up to 89%), very low no-load power consumption (<0.2 W), full protection functions, and 5G anti-vibration capability. It complies with international safety standards including UL60950-1, TUV EN60950-1, EN60335-1, EN61558-1/-2-16 and GB4943, making it suitable for industrial and commercial installations.

Advantages

Low-profile 30 mm design and compact footprint (99 × 82 × 30 mm) enable easy installation in space‑limited enclosures. Metal mesh housing and efficient conversion (up to 89%) provide good thermal performance for convection cooling from -30 °C to 70 °C without a fan. Extremely low standby consumption (<0.2 W) helps systems meet global energy-efficiency requirements. Built-in protections and 5G vibration resistance increase reliability in industrial environments.

Suitable for

• Industrial control cabinets and automation equipment
• Commercial appliances and point-of-sale systems
• Embedded systems and communication devices requiring 5 V DC
• Applications needing fanless convection cooling in restricted spaces

How to use

Mount the LRS-35-5 inside a ventilated enclosure with the metal mesh exposed to allow natural convection. Connect the AC input to the rated 85–264 VAC supply and the 5 V DC output to the load, observing polarity. Ensure the load does not exceed the 35 W rating and verify that wiring and fuses meet local electrical codes. Do not block ventilation openings and avoid mounting near heat sources to maintain the specified operating temperature range.

Usage recommendations

For reliable long-term operation, allow at least 10 mm clearance around the unit for airflow, use appropriate overcurrent protection on the DC output, and perform periodic inspections of connections in vibration-prone installations.
