High-Performance 35W 24V SMPS Switching Power Supply transformer for Industries

Short Description:

The LRS-35/50 series is a 35W/50W single-output enclosed power supply featuring a 30mm low-profile design and 85-264VAC wide-range AC input. The entire series provides outputs of 5V, 12V, 15V, 24V, 36V, and 48V. With an efficiency of up to 91.5%, its metal mesh enclosure enhances heat dissipation, allowing the LRS-35/50 to operate over a temperature range of -30°C to +70°C without a fan. Ultra-low no-load power consumption (below 0.3W) helps end systems easily comply with international energy efficiency requirements. The LRS-35/50 series offers full protection and 5G vibration resistance, and complies with international safety regulations including EN 60950-1, EN 60335-1, EN 61558-1/-2-16, and GB 4943. It provides 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.
Remarks	(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.
