INTRODUCTION
MEAN WELL’s uninterruptible DC-UPS module DR-UPS40 has been on the market for 15 years. In order to provide more cost-effective DC backup solutions, MEAN WELL has launched a new-generation DUPS20/40 series. The DC-UPS module is paired with a power supply and an external battery to achieve the backup function.

The main function of DUPS20/40 is to monitor DC output voltage as well as to charge the battery to ensure the continuous operation of entire system (backup period depends on the load and battery capacity). When the AC mains fails or is interrupted, the load will be immediately connected to the battery pack to avoid system equipment shut down therefore to prevent any data loss or financial loss. The product is suitable for use in factory automation, semiconductor fabrication equipment, security systems, emergency systems, data center, etc, where non-stop power to end device is required.
