Frequently Asked Questions
What is the Mean Well DRS-480-48 designed for?
The DRS-480-48 is an all-in-one intelligent security power unit that combines a 480W power supply, DC-UPS, battery charger, and status monitoring in one compact DIN rail model. It is aimed at security and power continuity applications where backup battery charging and alarm/status functions are important.
What are the main output specifications of the DRS-480-48?
This model provides a 48V DC output and is rated at 480W with a rated current of 7.7A. It is built for higher-power 48V applications that need both primary power and backup power support in a single unit.
What makes the DRS-480-48 different from a standard DIN rail power supply?
Unlike a standard DIN rail PSU, the DRS-480-48 integrates four functions in one unit: power supply, DC-UPS, battery charger, and status monitoring. It also includes relay contacts and LED indicators for conditions such as AC fail, battery low, charger fail, and DC-OK.
Is the DRS-480-48 suitable for battery-backed systems?
Yes. The DRS-480-48 is designed for battery-backed operation and supports both lead acid and lithium-ion batteries. It also offers selectable 2-stage or 3-stage charging, adjustable charging current from 20% to 100%, and load-dependent high-speed battery charging.
Can the DRS-480-48 be used in demanding environmental conditions?
This model is rated for operation from -30°C to +70°C, making it suitable for a wide range of industrial and security environments. Cooling is by free air convection, and the unit includes over-temperature protection with auto derating.
What monitoring and communication features does the DRS-480-48 include?
The DRS-480-48 includes built-in status monitoring with Form C relay contacts and LED indicators for key alarm conditions. It also supports Modbus protocol as standard, with CANBus available as an option, and some parameters can be adjusted through the communication interface.
What input range and approvals does the DRS-480-48 have?
The DRS-480-48 accepts a universal 90-305VAC input range and also supports 127-431VDC input. It is approved to UL62368-1 and RCM AS/NZS 62368.1, and its signal and alarm design is stated to meet UL2524, NFPA 1221, BS EN/EN54-4, and GB17945 requirements.
