ABB SD833 Power module

The ABB SD833 power module is a high-performance power supply solution from ABB. Designed to meet specific electrical safety standards and functional requirements, this power module is designed to provide a stable and reliable power supply.

The SD833 power module is a switching mode power supply unit that can convert the main voltage to 24 volts DC and is suitable for non-redundant and redundant applications. In redundant applications, it may be necessary to use with the diode voting unit SS823 or SS832. This power module does not require a power filter and provides a soft start function to prevent fuse or ground fault circuit breakers from tripping when powered on.

In terms of safety, the SD833 power supply module complies with European and international electrical safety standards such as EN 50178, EN 61131-2 and UL 508, and the secondary output circuit is suitable for SELV or PELV applications, providing overcurrent and overvoltage protection, thus ensuring the safety and stability of the power supply.

The SD833 power module also features a simple DIN rail mounting feature for easy device installation and configuration. In addition, it is a Class I device that can be used to connect to major TN networks when the overvoltage category is III.

Overall, the ABB SD833 power module is a high performance, safe and reliable power supply solution for a wide range of industrial automation and control systems requiring a stable DC power supply.
