DBUF20-24 Description

Short technical summary and product information.

The MEAN WELL DBUF20-24 buffer module is designed as a low-cost solution for short-term uninterruptible power supply (UPS) needs. Unlike traditional UPS systems, this module utilizes capacitors, eliminating the need for batteries. This design results in a smaller footprint, increased cost-effectiveness, and maintenance-free operation.

 

The DBUF20-24 offers a faster response time compared to battery-based UPS units. It provides a typical buffering time of 350ms at 22VDC and 20A. For applications requiring longer buffering durations, multiple units can be connected in parallel.

 

This buffer module is suitable for use with 24V power supplies and is designed for DIN rail mounting, making integration into industrial control systems straightforward. Its electronic-mechanical design ensures reliable performance in various applications requiring temporary power backup during brief interruptions.

 

Key features include its capacitor-based buffering technology, DIN rail mounting capability, and suitability for 24V systems. The module's design prioritizes efficiency and ease of use for industrial power management solutions.
