Mornsun LM50-20B12 AC/DC 50W Enclosed SMPS The LM50-20B12 is a 50 watt, 12 volt, 4.2 amp switch-mode power supply (SMPS) from Mornsun. It is a non-isolated, positive output SMPS that is designed for use in a variety of applications, including industrial automation, networking, and telecommunications. The LM50-20B12 features a wide input voltage range of 100 to 240 VAC, making it suitable for use in a variety of global markets. It also features a high efficiency of up to 88%, which helps to reduce power consumption and heat dissipation. The LM50-20B12 is a compact and lightweight unit that measures just 2.2 x 2.2 x 1.2 inches and weighs only 0.4 pounds. It is also built to withstand harsh environmental conditions, with an operating temperature range of -20 to 60 degrees Celsius and a relative humidity range of 0 to 95%. Note: Unless otherwise specified, parameters in this datasheet were measured under the conditions of Ta=25?, humidity<75%RH with nominal input voltage and rated output load The room temperature derating of 5?/1000m is needed for operating altitude greater than 2000m All index testing methods in this datasheet are based on our company's corporate standards In order to improve the efficiency at high input voltage, there will be audible noise generated, but it does not affect product performance and reliability The out case needs to be connected to the earth ( )of system when the terminal equipment in operating The output voltage can be adjusted by the ADJ, clockwise to increase Our products shall be classified according to ISO14001 and related environmental laws and regulations and shall be handled by qualified units The power supply is considered a component which will be installed into the final equipment. All EMC tests should be confirmed with the final equipment
