Meanwell ELG-150-24 ELG-150 series AC/DC LED driver

The Mean Well ELG-150-24 is a part of the ELG - 150 series of AC/DC LED drivers. Here are its detailed parameter information:

1. Electrical Specifications

Input Side

• Input Voltage Range: It can accept a wide input voltage range of 90 - 305VAC. This wide range makes it suitable for use in different regions around the world with varying mains voltages.

• Input Frequency: The input frequency range is 47 - 63Hz, which is compatible with the standard power frequencies used in most countries.

• Inrush Current: At 230VAC input, the inrush current is typically less than 40A at cold start. This specification helps protect the power supply and other components in the circuit from excessive current surges during startup.

• Power Factor: It has a high power factor, usually greater than 0.95 (at 230VAC input). A high power factor means that the driver can efficiently convert the incoming AC power into DC power for the LEDs, reducing energy waste and complying with energy - efficiency regulations.

Output Side

• Output Voltage: The output voltage is fixed at 24V DC. This specific voltage is designed to match the requirements of 24V LED lighting systems.

• Output Power: It can deliver a maximum output power of 150W. This power rating determines the number and type of LEDs that can be powered by the driver.

• Output Current: Using the formula I=VP (where P=150W and V=24V), the maximum output current is 6.25A.

• Output Ripple & Noise: The output ripple and noise are kept at a low level, typically within 250mVp - p. Low ripple and noise ensure stable operation of the LEDs and prevent flickering.

2. Performance Characteristics

• Efficiency: The driver has a high efficiency, up to 91%. High efficiency means less power is wasted as heat during the conversion process from AC to DC, resulting in lower energy consumption and longer lifespan of the driver.

• Regulation:

• Line Regulation: It is typically within ±0.5%. This means that the output voltage remains relatively stable even when the input voltage fluctuates within the specified range.

• Load Regulation: Usually within ±1%, ensuring that the output voltage remains consistent as the load (connected LEDs) changes.
