MEAN WELL DUPS20/40 Uninterruptible DC-UPS Modules

MEAN WELL DUPS20/40 Uninterruptible DC-UPS Modules offer either 20A or 40A rated current, 24VDC to 29VDC input voltage range, and -30°C to +70°C temperature range. The DC-UPS module is paired with a power supply and an external battery to achieve the backup function, and the main function of the DUPS20/40 modules is to monitor DC output voltage and charge the battery to ensure the continuous operation of the entire system. When the AC mains is interrupted or fails, the load will immediately be connected to the battery pack to avoid system equipment shutdown, preventing any data or financial loss. MEAN WELL DUPS20/40 Uninterruptible DC-UPS Modules are ideal for industrial control systems, factory automation, electromechanical apparatus, and semiconductor fabrication equipment.
