The compact 30 mm low profile design and perforated metallic enclosure help dissipate heat without requiring an internal cooling fan.

Mean Well specifies the LRS-150 series for applications including industrial automation machinery, industrial control systems, mechanical and electrical equipment, electronic instruments and household appliances.

B. Working Principle

The Mean Well LRS-150-24 works as an AC to DC switching power supply.

Incoming AC power first passes through an EMI filter that helps reduce electrical interference. The AC supply is then rectified and filtered before entering the high frequency power switching section.

The switching circuit operates at approximately 65 kHz. The switched electrical energy passes through an isolation transformer and is then rectified and filtered again on the output side to produce regulated DC power.

The control and detection circuits continuously monitor the output and regulate the switching operation so that the power supply maintains a stable 24V DC output under normal operating conditions.

The internal circuitry also includes protection functions for:

Short circuit protection
Overload protection
Overvoltage protection
Overtemperature protection

For overload conditions, the unit uses hiccup mode and automatically recovers after the fault condition is removed.

C. Why Mean Well LRS-150-24 Is Used

The Mean Well LRS-150-24 is used when equipment requires a reliable 24V DC power supply with up to 6.5A output current.

Its 24V DC output is suitable for many industrial automation and electrical control applications. The adjustable output range of 21.6V to 28.8V DC also allows the output voltage to be fine tuned according to system requirements.

It is commonly selected because it provides a combination of compact size, high efficiency, natural convection cooling and multiple electrical protection functions.

The LRS-150 series also features a no load power consumption of less than 0.5W, 5G vibration resistance, an LED power indicator and a three year manufacturer warranty.
