DUPS20

DUPS20 is a DIN rail-type uninterruptible DC-UPS module. 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 continuous operation of the entire system. The main features include fast installation, small size (only 40mm wide), suitability for 24V battery packs and various capabilities of 4AH-135AH, 2A battery charging current, low voltage disconnect for battery protection and more. Protections include battery reverse polarity protection and short circuit/battery discharge/over-discharge current. It is suitable for use in data centres, security systems, emergency lighting, wireless communication UPS, central monitoring systems, etc. Typical applications include industrial control systems, semiconductor fabrication equipment, factory automation, and electromechanical apparatus.
