UPS Mean Well on DIN rail from 20/40 A - 2021

September 29, 2021

The DC-UPS continuity module from MEAN WELL's DR-UPS40 series has been on the market for 15 years.

To ensure product reliability, offering better and more cost-effective DC backup solutions, Mean Well has launched the new DUPS20/40 series.

The DC-UPS module is connected with a power supply and an external battery to achieve the backup function.

The main function of the DUPS20/40 series is to monitor the DC output voltage and charge the battery to ensure continuous operation of the entire system (the backup period depends on the load and battery capacity).

When the AC mains power is lost or interrupted, such as during a blackout, the load is immediately switched to the battery to prevent system shutdown and thereby prevent any data loss.

What applications is the Mean Well DUPS20/40 series used for?

The DUPS20/40 series is designed to be used in applications where continuous power to the end device is required, such as:

• industrial automation
• semiconductor manufacturing equipment
• security systems
• emergency systems
• data centers
