Mean Well DRS-240-36 All-In-One Intelligent Security Power 240W

The DRS-240-36 is an all-in-one intelligent security power unit designed for systems that need a 36V DC supply with backup power support. It combines a power supply, DC-UPS, battery charger, and status monitoring in one compact DIN rail form factor.

This model is rated for 240W output at 36V DC with a rated current of 5.1A. It accepts a wide input range of 90 to 305VAC or 127 to 431VDC, which helps it suit a broad range of industrial and security power environments.

Unlike a standard DIN rail power supply that only provides DC output, the DRS-240-36 also integrates DC-UPS capability, battery charging, and status monitoring. It is intended for applications where backup power continuity and fault status visibility matter, especially in security-related systems.

The DRS-240-36 is suitable for both lead acid and lithium-ion batteries. It also offers selectable 2-stage or 3-stage charging, and its charging current is adjustable from 20% to 100% by VR.

Yes, this model is specified for operation from -30°C to +70°C. It uses free air convection cooling and includes over-temperature protection with auto derating, which supports use in tougher industrial environments.

The unit includes Form C relay contacts and LED indicators for AC Fail, Battery Low, Charger Fail, and DC-OK status. It also has built-in MODBus protocol support, with CANBus available as an option, for broader system monitoring integration.

The DRS-240-36 includes protection for short circuit, overload, over voltage, over temperature with auto derating, battery reverse polarity, and battery cut off. These built-in protections help support reliability in critical power applications.

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, and it also lists EMC compliance including EN55032 Class B.
