Meanwell DUPS40
24V/40A DIN Rail Type Uninterruptible DC-UPS Module
The DUPS40 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 continuous 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 packs 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 lighting, wireless communication UPS, central monitoring systems, etc.
Features:
- Uninterruptible DC-UPS controller
- Parallel connection to DC BUS (Power supply + DC-UPS Module + Batteries + Load)
- Suitable for 24V system, up to 40A
- 2A Battery charging current
- Allows 4AH~135AH lead-acid various battery capacities
- Complete diagnostic and monitoring for DC BUS OK, battery discharge, battery fail
- LED indicator for signal status
- Protections: Battery reverse polarity protection & Short circuit(By internal detection) / Battery discharge / Over discharge current
- Cooling by free air convection
- 3 years warranty
Applications:
- Industrial control system
- Semiconductor fabrication equipment
- Factory automation
- Electro-mechanical apparatus
