Factory Direct Sale MS 50W 75W AC-DC Converter SMPS Switching Power Supply Transformer

Short Description:

The MS-50, 60, 75 series is a 50W/60W/75W single-output enclosed power supply with an 85–264VAC wide-range AC input. The entire series provides 5V, 12V, 15V, 24V, 36V, and 48V output options. In addition to an efficiency of up to 91.5%, the metal mesh enclosure is designed to enhance heat dissipation, allowing the MS-50/60/75 to operate over a temperature range of –30°C to +70°C without a fan. Ultra-low no-load power consumption enables end systems to easily meet international energy efficiency requirements.

The MS-50/60/75 series features complete protection and 3G vibration resistance, and complies with international safety standards including EN 60950-1, EN 60335-1, EN 61558-1/-2-16, and GB 4943. It offers a cost-effective solution for a wide range of industrial applications.

Remarks	(1)Measurement of ripple and noise: Using a 12 “twisted-pair line with a capacitor of 0.1uF and 47uF in parallel at the terminal,the measurement is carried out at 20MHz bandwidth.
	(2)Efficiency is tested at the input voltage of 230VAC,rated load and 25ºC ambient temperature.Accuracy: including setting error,linear adjustment rate and load adjustmient rate.Test method of linear adjustment rate: testing from low voltage to high voltage at rated loadLoad adjustment rate test method: from 0%-100% rated load.The start-up time is measured in the cold start state, and the fast frequent switch machine may increase the startup time.When the altitude is above 2000 meters, the operating temperature should be lowered by 5/1000.
