The MeanWell ELG-150-54 is an AC/DC LED driver designed to provide a stable power supply for LED lighting systems. Here is a detailed parameter introduction:
Input Voltage Range: It typically supports a wide input voltage range, usually from 90 - 305VAC. This wide range allows it to be used in different regions with varying mains voltages, enhancing its adaptability and usability across the globe.
Frequency Range: The input frequency range is commonly 47 - 63Hz, which is compatible with the standard power frequencies used in most countries.
Inrush Current: At 230VAC input, the inrush current is usually less than a certain value (e.g., 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, often 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 Voltage: The output voltage is fixed at 54V DC. This specific voltage is designed to match the requirements of certain LED lighting configurations.
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: The output current can be calculated based on the output power and voltage. Using the formula I=VP, with P=150W and V=54V, the output current is approximately 2.78A. However, the actual current may vary depending on the load and the driver's design.
The driver has a high efficiency, typically around 90% or higher. High efficiency means that less power is wasted as heat during the conversion process from AC to DC, resulting in lower energy consumption and less heat generation.
Line Regulation: It has good line regulation, usually within ±0.5%. This means that the output voltage remains relatively stable even when the input voltage fluctuates within the specified range.
Load Regulation: The load regulation is also well - controlled, typically within ±1%. This ensures that the output voltage remains consistent as the load (connected LEDs) changes.
Over - Voltage Protection (OVP): In case the output voltage exceeds a certain safe level, the driver will automatically shut down to protect the connected LEDs from damage. The OVP set - point is usually around 60 - 65V for this model.
Over - Current Protection (OCP): If the output current exceeds the rated value, the driver will limit the current or shut down to prevent overheating and damage to the LEDs and the driver itself.
Short - Circuit Protection (SCP): When a short - circuit occurs at the output, the driver will quickly cut off the power to protect the components. After the short - circuit is removed, the driver can usually resume normal operation automatically.
Over - Temperature Protection (OTP): If the internal temperature of the driver rises above a certain threshold (e.g., 85 - 90°C), the driver will reduce the output power or shut down to prevent overheating and ensure long - term reliability.
Operating Temperature Range: It can operate within a wide temperature range, typically from - 30°C to + 70°C. This allows it to be used in various indoor and outdoor environments.
Storage Temperature Range: The storage temperature range is usually from - 40°C to + 85°C.
Humidity: It can withstand a relative humidity range of 10 - 95% (non - condensing), which means it can be used in environments with different levels of humidity without being damaged by moisture.
Dimensions: The driver has specific dimensions, for example, it might be around 190mm (L) x 85mm (W) x 40mm (H). The compact size makes it easy to install in different lighting fixtures.
Weight: It typically weighs around 500 - 600 grams, which is relatively lightweight and convenient for handling and installation.
