ABB SD832 Switch-Mode Power Supply 5A 24V DC

ABB SD832 Industrial Power Supply Unit

The SD832 Power Supply Units are designed to meet all applicable electrical safety standards, including EN 50178, EN 61131-2, and UL 508. As switch-mode units, they convert mains voltage to 24V DC and support both non-redundant and redundant applications (with diode voting units SS823/SS832 for redundancy).

Key Features & Benefits

• Simple DIN-rail mounting for easy installation
• Class I Equipment (requires Protective Earth connection)
• Over-voltage Category III for primary main TN network connection
• Protective separation between primary and secondary circuits
• Supports SELV and PELV applications for safe low-voltage use
• Over-current (current limit) and over-voltage (OVP) protection
• Soft-start feature to prevent fuse or circuit breaker tripping on power-on

Technical Specifications

• Article Number: 3BSC610065R1
• Rated Output: 24V DC, 5A (120W); max 6A at <45°C ambient
• Input Voltage: Auto-select 100-120V/200-240V AC (50-60Hz)
• Efficiency: Up to 90.2%
• Certifications: CE-marked; marine certifications (ABS, BV, DNV-GL, LR)
• Dimensions: 32mm width (DIN-rail), 117mm depth, 124mm height

Application Notes

The SD832 is ideal for powering industrial control systems, PLCs, sensors, and actuators. It requires no external mains filter and maintains stable output with low ripple (<50mV) and voltage regulation (<100mV at max current).
