ABB SD834 Power Supply Device

Description

The ABB SD834 Power Supply Device is a high-performance power supply for industrial automation systems, part of the ABB Ability series. It supports flexible input configurations, accepting alternating current 100-240V or direct current 110-150V, and delivers a stable direct current 24V output. With a rated output power of 480W and rated input power of 547/568VA, it offers adjustable output current options ranging from 3A to 20A, with a standard 20A rating. The device achieves high energy efficiency of 88% to 89.8%, with output ripple limited to ≤50mV for clean power delivery.

Key features include a compact DIN rail mounting design (35mm rail) that saves installation space, and advanced switching power supply technology that provides multiple protection functions including overload, short circuit, and overvoltage protection for enhanced reliability. It supports redundant configuration with a built-in voter to boost system uptime, and can be paralleled to increase total output power. Operating in temperatures from -20 degrees Celsius to 55 degrees Celsius, it meets international certifications including CE, IEC 61131-2, UL 508, and EN 50178. Ideal for both non-redundant and redundant applications, it is widely used in industrial automation, control systems, power distribution, manufacturing, energy, and food and beverage processing to supply stable power to equipment like robots, conveyor lines, and process control modules.
