PQA30-D24-S3-TH is an isolated DC-DC converter module from the PQA30-T series designed to convert 24V nominal input to a regulated 3.3V output. The module operates across an input voltage range of 18-36V and delivers up to 20W of output power with a maximum output current of 6A. It features 1,500V DC isolation, comprehensive protection including short circuit, over-current, and over-voltage protection, plus inverse polarity protection. The converter achieves 85% typical efficiency and operates reliably across an extended temperature range of -40°C to +85°C. With its compact package, six-sided metal shielding, and remote on/off capability, this module is well-suited for industrial control systems, telecommunications equipment, and embedded power applications requiring galvanic isolation and high reliability.
