📐 Ideal Use Case

This ultra-compact, high-reliability 24 V/0.5 A SMPS is designed for control cabinets and automation systems with limited space. With reliable protections, soft-start behavior, and wide operating temperature, it’s suitable for industrial environments—though as a discontinued unit, long-term procurement would require buying remaining stock or planning migration to the PSU100C 0.6 A successor.
