Description

The UPDS40 is a 40A DIN rail type DC-UPS module, and it is paired with a power supply and an external battery to achieve the backup function. When the AC mains fails or is interrupted, the load will be immediately connected to the battery pack to avoid interruption and to ensure the continous operation of the entire system (the operating time depends on the capacity of the battery pack).

The main features of DUPS40 include: fast installation, suitability for 24V battery pack and various capacities of 4Ah ~ 135Ah, 2A battery charging current, low voltage disconnect for battery protection and more. The product is suitable for use in data centers, security systems, emergency lightning, wireless communication UPS, central monitoring systems etc.
