LED power supply 40W 24V 1.67A PWM-40-24

Universal LED power supply with dimming function

The PWM-40-24 LED power supply is a reliable power source for LED lighting systems. Designed by MEAN WELL, it offers an output power of 40W at a voltage of 24V and a current of 1.67A. This is a solid solution for both professional installers and end-users looking for efficient and durable power for their installations.

Construction and functionality

The power supply's construction is based on a wide input voltage range (90-305VAC, 127-431VDC), which ensures compatibility with various electrical networks. The sealed plastic housing (IP67) protects against weather conditions and allows for mounting in various environments – even those exposed to moisture or dust. The use of an active PFC (Power Factor Correction) circuit improves energy efficiency and minimizes interference in the power grid.

The power supply is characterized by high efficiency, reaching up to 90%, which translates to lower energy consumption and less heat loss. Additionally, it has built-in protection against short circuits, overload, overvoltage, and overheating, which guarantees safe operation and long device life. The no-load power consumption is minimal – less than 0.5W.

Control flexibility and applications

One of the key features of this power supply is the 3-in-1 dimming function: 0-10VDC, PWM (Pulse Width Modulation), and resistance control. This allows for smooth adjustment of LED brightness, adapting the lighting to individual needs and preferences. Cooling is done by natural air convection, which eliminates the need for additional fans and ensures quiet operation. The power supply operates in a wide temperature range – from -40°C to +70°C – making it an ideal solution for outdoor applications and in harsh industrial conditions. It complies with many standards and has certificates confirming its quality and safety.
