Robers & Schulz GNR 1/24 Power Supply

Got this Robers & Schulz power supply unit up for grabs. It's a GNR 1/24 model, looks like it takes 115 or 230V AC and puts out 24V DC at 1 amp. It's a bit dusty from sitting around but the housing is solid. Good for industrial projects or if you're building out a control panel and need a reliable DIN rail mount supply. Not sure on the exact age but these things are built like tanks.
