The Mean Well LRS power supply series is offered in 35, 50, 75, 100, 150, 200 and 350 Watt models. These open frame power supplies take AC line voltage input and provide constant DC output voltage lines of 5V, 12V, 15V, 24V, 36V and 48V. These single-output enclosed type power supplies sit at just 30mm tall for a low profile design you can easily mount within your application.
Low Line & High Line Voltage
LRS-35/50/75/100: Adopt the full range 85-264VAC input.
LRS-150/200/350: Adjustable input voltage 115VAC or 230VAC (select via switch)
Open Frame Switching Power Supplies, as you can see from the picture, are power sources where the circuit board and components are encased in a metal casing with small holes throughout. This aids in air flow and cooling as the components are all open to the outside air. When dealing with a lot of power, it is best to make sure there is a way to control the heat. Operating temperatures vary by size, see data sheet documentation below for exact technical info on each one.
The LRS-350 series actually has a built in fan to aid in heat control. This is the only model that uses this design as it is carrying larger loads and heat is more likely.
All connections are made via screw-in terminals. This makes it super easy to connect all your wires with input ports for your line voltage and couple different output ports if you have multiple lights powered by the one power supply.
There are mounting holes on the power supply if you need to mount to an object. Another way to mount would be using double sided velcro or tape.
