This model features a sophisticated triple-output design that provides a stable 27.6V main output, a secondary 5V rail for logic circuits, and a dedicated 27.1V battery charging channel. Equipped with built-in active PFC (Power Factor Correction), it ensures high energy efficiency and compliance with global harmonic current standards. The fanless design utilizes natural air convection for cooling, which eliminates mechanical noise and significantly enhances the long-term reliability of the unit in dust-sensitive industrial environments. Designed for mission-critical security and monitoring infrastructure, the ADD-155B offers specialized battery low and battery polarity protections to safeguard your energy storage assets against accidental damage. The main output (CH1) is highly flexible, featuring a voltage adjustment range of 24V to 29V to account for specific battery chemistry requirements or potential voltage drops over long cable runs. With professional-grade features such as a 100% full load burn-in test and a comprehensive safety suite including UL62368-1 and TUV certification, this power supply is the ideal solution for 24V security systems, emergency telecommunications, and automated control cabinets that demand uninterruptible power delivery.

Technical Information & Details for the MEAN WELL SDR-480-24 Power Supply Output Power: 480 W (720 W Peak) Output Voltage: 24 V DC Output Current: 20 A Input Voltage Range: 90 – 264 V AC / 127 – 370 V DC, 47 – 63 Hz Efficiency: 94% Ripple & Noise: ≤ 100 mVp-p Inrush Current: 40 A @ 115 VAC / 80 A @ 230 VAC Power Factor: PF > 0.94 Operating Temperature: -25 °C to +70 °C Cooling: Free air convection Protection Functions: Short circuit, Overload, Over voltage, Over temperature Voltage Adjustment Range: 24 – 28 V Isolation Voltage: 3000 V AC I/P-O/P Dimensions (W x H x D): 85.5 mm x 125.2 mm x 128.5 mm Weight: 1.6 kg Safety & EMC Certificates: UL 508, TUV EN62368-1, BS EN/EN61000-6-2, EAC, CE Status Indicators: DC OK relay contact and LED indicator Manufacturer Warranty: 3 Years Information about the MEAN WELL SDR-480-24 The MEAN WELL SDR-480-24 stands out as a high-performance solution for demanding industrial environments, boasting an impressive efficiency of up to 94%. This high efficiency significantly minimizes power dissipation, allowing the unit to operate reliably using only free air convection cooling within a slim 85.5mm chassis. One of its most critical advantages is the 150% peak load capability, which enables the power supply to deliver up to 720W for 3 seconds. This feature is particularly vital for powering loads with high startup currents, such as motors or capacitive loads, ensuring system stability without the need to over-dimension the power supply unit. Engineered for maximum reliability, the SDR-480-24 includes a built-in active PFC function and a DC OK relay contact for remote monitoring of the output status. The unit is fully compliant with industrial immunity levels (EN61000-6-2) and carries UL 508 approval, making it a robust choice for industrial control systems, fabrication equipment, and automation machinery. With its constant current limiting circuit and comprehensive protections against short circuits and over-temperature, this DIN rail power supply ensures long-term operational safety and minimal maintenance requirements in complex hardware setups.
