Product Overview
The ABB SS823 (Article Number: 3BSE038226R1) is a high-reliability power voting and overvoltage protection module weighing 870 g (1.9 lbs). Designed for redundant 24 V DC power supply configurations, it supports a rated input power of 500 W and a continuous output current of 20 A. The SS823 ensures uninterrupted power distribution and voltage protection for mission-critical automation systems.
Key Features
- Redundant Power Voting: Enables dual power supply voting to maintain continuous 24 V DC system operation if a primary power unit fails.
- Integrated Overvoltage Protection: Safeguards sensitive downstream control hardware against sudden voltage surges.
- High Current Capacity: Handles up to 20 A rated output current and 500 W input power in a compact footprint.
- Standardized Cabinet Integration: 116 mm width with predefined mounting clearances (15 mm horizontal, 30 mm vertical) for optimal thermal management.
Installation Essentials
Mount the SS823 module vertically inside a control cabinet, observing the recommended mounting clearances of 15 mm on the sides and 30 mm top/bottom to facilitate natural convection cooling. Wire the 24 V DC inputs securely according to polarity standards before connecting the 20 A output load.
