Mean Well DRS-240-12 All-In-One Intelligent Security Power 240W

The DRS-240-12 combines four functions in one compact unit: a 240W power supply, DC-UPS, battery charger, and status monitoring. That makes it better suited to security and critical-power systems than a basic DIN rail PSU that only provides 12VDC output. It also includes relay contacts and LED indicators for AC fail, battery low, charger fail, and DC-OK status.

This model is designed for intelligent security and backup-power applications where 12VDC must stay available during mains interruptions. It is a practical fit for security control panels, monitored alarm systems, and other DIN rail control cabinets that need integrated charging and DC-UPS capability. Its signal and alarm design is intended for regulated safety and security environments.

Yes. The DRS-240-12 supports both lead acid and lithium-ion batteries, with selectable 2-stage or 3-stage charging. Charging current is adjustable from 20% to 100%, and the charging curve can also be set with the SBP-001. That gives buyers more flexibility when matching the unit to different standby power requirements.

The DRS-240-12 is rated at 240W and provides a 12VDC output with rated current up to 15.4A. It accepts a wide 90 to 305VAC input range, with 127 to 431VDC input also supported. Overload, over-voltage, over-temperature, battery reverse polarity, and battery cut-off protections are built in.

It is built for a wide operating temperature range of -30°C to +70°C and uses free air convection cooling. The unit is also rated for vibration performance across the X, Y, and Z axes, which helps in control cabinet and industrial environments. Buyers should still confirm the enclosure design supports the unit's thermal conditions.

Yes. The unit includes built-in MODBus protocol, with CANBus available as an option. It also provides Form C relay contacts and front-panel LED indication for key status conditions including AC fail, battery low, charger fail, and DC-OK. This makes it suitable for systems where remote status visibility or alarm signaling matters.

The DRS-240-12 is approved to UL62368-1 and RCM AS/NZS 62368.1, and its EMC compliance includes EN55032 Class B plus EN61000-3-2 and EN61000-4 series standards. Its signal and alarm design is stated to meet UL2524, NFPA 1221, BS EN/EN54-4, and GB17945 requirements. That standards coverage is a key reason buyers choose it for security-related power systems.
