Product Description
MEAN WELL DBUF40-24 is a high-quality 24V dc input buffer module designed for DIN Rail mounting, primarily used to supplement regulated DC 24V power supplies in industrial and commercial electrical systems. The module enhances system reliability by increasing output current capacity and providing a hold-up buffer time of 25 seconds. It achieves this by employing maintenance-free electrolytic capacitors to store energy, eliminating the need for periodic battery replacements and offering a longer functional lifespan compared to traditional lead-acid batteries.
The DBUF40-24 features an LED indicator for clear signal status, enabling easy monitoring during operation. Its design supports parallel connections, allowing users to extend buffering time as per application requirements. The module dissipates heat through free air convection, which reduces maintenance and eliminates the need for additional cooling devices.
Measuring 125.2mm in length, 63mm in width, and 114.9mm in depth, this compact module easily integrates into DIN Rail-mounted setups within industrial automation, power supply stabilization, and uninterruptible power supply (UPS) systems.
It complies with a variety of stringent international standards such as EN55035, EN55032, EN61000 series for electromagnetic compatibility, as well as UL62368-1 and IEC62368-1 for safety, making it suitable for deployment in industrial, manufacturing, HVAC, and electrical distribution applications.
This buffer module supports parallel connection to increase output ampacity and hold-up time. Use of maintenance-free electrolytic capacitors avoids frequent replacements compared to batteries. Includes an LED indicator for easy status monitoring.
Designed for DIN Rail mounting for flexible integration. Operates with passive cooling via free air convection. Compact dimensions suit tight installation spaces. Certified to multiple international standards ensuring reliability and safety.
