MeloAuto-Trusted PLC & DCS Parts Supplier
Technical Specifications and Supply Design
This power supply provides regulated DC power for ABB AC500 and AC31 PLC systems. The ABB 200-PSSG converts incoming AC voltage into stable 24V DC output. You can mount this unit directly onto a standard DIN rail in your cabinet. Its slim design saves valuable space next to other control components. The supply weighs approximately 0.35 kilograms. Its dimensions measure 10 cm in height, 5 cm in width, and 9 cm in depth.

Output Regulation and Protection Features
The supply delivers a clean 24V DC output with ±2% regulation accuracy. It maintains stable voltage even with wide input fluctuations. The ABB 200-PSSG includes built-in overload and short-circuit protection circuits. A hiccup mode resets automatically after removing the fault condition. The supply also features overvoltage protection using a crowbar circuit. A green LED indicates proper output voltage and normal operation. The supply operates at 88% efficiency, reducing heat generation in your cabinet.
Energy Storage and Ride-Through Capability
The built-in DC bus capacitors store energy for brief power interruptions. These capacitors provide 30 milliseconds of hold-up time at full rated load. Consequently, your PLC continues operating through momentary voltage sags. The supply uses a universal input stage for worldwide compatibility. You do not need any voltage selector switches for different countries. The unit provides full rated output from -25°C to +70°C ambient temperature. Power derating begins above 50°C for continuous operation.
Installation and Operational Guidelines
You must clip this supply onto a standard 35 mm DIN rail securely. The unit accepts solid or stranded wires from 0.2 to 2.5 mm². The ABB 200-PSSG requires no external fuses for normal operation. However, you should use a 6 Amp circuit breaker for input protection. You must connect the protective earth terminal for safety compliance. The supply requires no external battery for normal power conversion operation. You should allow 20 mm clearance above and below for cooling airflow. The terminal cover prevents accidental contact with live terminals after installation.
