75W 12V 24V 36V 48V Switching Power Supply AC DC Converter 6 Outputs for Industrial Equipment

Product Description

Product Description

The LRS-75 series is a high-efficiency, compact enclosed single-output switching power supply designed for industrial automation, instrumentation, LED lighting, communication equipment and general civil electrical systems. Adopting universal full-range AC input of 85~264VAC and 120~373VDC wide DC input, this 75W power supply supports six mainstream DC output specifications including 5V, 12V, 15V, 24V, 36V and 48V to meet diverse industrial and commercial power supply demands. Featuring ultra-low no-load power consumption, high conversion efficiency, precise voltage output and excellent anti-interference capability, the LRS-75 series delivers stable, reliable and energy-saving power performance for long-term continuous operation scenarios. With complete safety certifications and wide temperature adaptability, it is a cost-effective universal industrial power supply solution for global users.

Universal Wide Input & Precise Output Stability

Supports 85~264VAC full-range global voltage input, compatible with power grids in all regions. Strictly controlled voltage tolerance within ±1.0% for most models, line regulation ±0.5% and load regulation as low as ±0.5%. The output voltage remains highly stable under fluctuating grid voltage and variable load conditions, effectively protecting precision electronic equipment.

Multiple Protection & Automatic Recovery Function

Strong Environmental Adaptability & Durability

Built-in complete protection mechanisms including overload protection (110%~150% rated power) and over-voltage protection. The overload hiccup mode enables automatic recovery after fault elimination; over-voltage protection shuts down output instantly to avoid equipment burnout, ensuring safe and stable long-term operation.

Supports wide working temperature range of -30℃ to +70℃, maintaining stable performance in high and low temperature harsh environments. Passes strict 5G multi-axis vibration test, effectively resisting vibration and impact during equipment operation and transportation, with excellent structural durability.
