MEAN WELL LRS-75 Single Output Switching Power Supplies

MEAN WELL LRS-75 Single Output Switching Power Supplies are 75W enclosed-type power supplies with a 30mm low-profile design. With a full 85VAC to 264VAC input range, the LRS-75 power supplies provide an output voltage line of 5V, 12V, 15V, 24V, 36V, and 48V. In addition to the high efficiency up to 91.5%, the metallic mesh case enhances heat dissipation in a temperature range of -30°C to +70°C under air convection without a fan. Delivering a low no-load power consumption (less than 0.3W), the end system design easily meets worldwide energy requirements.
