Manufacturer Price S-120W Switching Power Supply Transformer for LED Strip Light

Short Description:

The S-100, 120, 150 series is a 100W/120W/150W single-output enclosed power supply featuring an 85-264VAC wide-range AC input.

The entire series provides 5V, 12V, 15V, 24V, 36V, and 48V output options. With an efficiency of up to 91.5%, its metal mesh housing enhances heat dissipation, enabling the S-100/120/150 to operate over a temperature range of -30°C to +70°C without a fan. Ultra-low no-load power consumption ensures end systems can easily meet international energy efficiency requirements. The S-100/120/150 series offers complete protection and 3G vibration resistance, and complies with international safety standards including TUV EN 60950-1, EN 60335-1, EN 61558-1/-2-16, UL 60950-1, 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.
	(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.

What is the difference between regulated power supply and switching power supply?

There are two topologies to consider for this goal, linear regulated and switch mode power supplies. Linear regulated is ideal for applications that require low noise, whereas switching power supplies are better suited for handheld devices where battery life and efficiency is important.
