ABB SB822 Rechargeable Battery Unit

Description

The ABB SB822 Rechargeable Battery Unit is a lithium-ion battery module designed for industrial automation and control systems, primarily serving as a backup power source to prevent data loss and ensure continuous operation during main power failures. Key technical specifications include a 3.6V rated output voltage, 0.05A maximum output current, and a lithium metal equivalent of 0.8g (0.03 ounces). It operates within a temperature range of -20 degrees Celsius to 60 degrees Celsius, with some variants rated for -25 degrees Celsius to 70 degrees Celsius, and weighs 0.2kg. Physical dimensions are listed as either 184.5mm length, 76.5mm width, 139.5mm height, or 16cm length, 85mm width, 12cm height.

Featuring a DIN rail mounting design, the unit includes a lithium-ion battery, 24V DC connector, and TK821V020 connection cable for easy installation and maintenance. It boasts IP20 protection compliant with IEC 60529 standards, low self-discharge rate for long-term charge retention, and high reliability with rapid switchover to backup power when needed. Its compact form saves panel space, and its 24V DC output is compatible with various ABB control systems, including the AC 800M controller. Typical applications span industrial automation, building automation, critical infrastructure, and data centers, supporting devices such as PLCs, HMIs, HVAC systems, lighting systems, communication equipment, servers, and network devices.
