Mean Well DRS-480-24 All-In-One Intelligent Security Power 480W

The DRS-480-24 is designed for security and backup power applications that need more than a standard DIN rail power supply. It combines a 24V DC power supply, DC-UPS, battery charger, and status monitoring in one compact unit. That makes it suitable for systems where continuous operation and power status visibility matter.

Unlike a basic 24V DIN rail PSU, the DRS-480-24 integrates UPS and battery charging functions along with monitoring and alarm outputs. It also supports status indication for conditions such as AC fail, battery low, charger fail, and DC-OK. This makes it a stronger fit for critical security and standby power systems.

This model is rated for 480W output at 24V DC with a rated current of 15.4A. It accepts a wide input range of 90 to 305VAC or 127 to 431VDC. The unit also includes overload, over voltage, over temperature, short circuit, battery reverse polarity, and battery cut off protection.

Yes, the DRS-480-24 is suitable for both lead acid and lithium-ion batteries. It supports selectable 2-stage or 3-stage charging, and the charging current is adjustable from 20% to 100%. That gives buyers flexibility when matching the unit to the battery chemistry used in the system.

Yes, this model includes status monitoring features intended for higher-reliability applications. It provides Form C relay contacts and LED indicators for AC fail, battery low, charger fail, and DC-OK conditions. It also has built-in MODBus protocol, with CANBus available as an option.

The DRS-480-24 is rated for operation from -30°C to +70°C, which supports use in a wide range of industrial and security environments. Cooling is by free air convection, so it is designed without forced-air cooling fans. Its DIN rail form factor also suits control cabinet and panel-based installations.

This model is approved to UL62368-1 and RCM AS/NZS 62368.1 safety standards. Its signal and alarm design is stated to meet UL2524, NFPA 1221, BS EN/EN54-4, and GB17945 requirements. EMC compliance includes EN55032 Class B and multiple EN61000 immunity and emissions standards.
