The Polytron P51-15QX is an enclosed AC/DC converter designed for ITE (Commercial) applications. It offers a 5V output and +/-15V outputs, with current ratings of 250mA for the 5V output and 50mA for each +/-15V output. The unit supports an input voltage range of 105-125 Vac at 50-60 Hz, with 400Hz also available.
Key electrical specifications include a line regulation of ±0.2% and a load regulation of ±0.2% for single outputs. The voltage accuracy at full load is ±1.0%, and it has a temperature coefficient of ±0.02%/°C typical. Isolation resistance is rated at a minimum of 50 MOhms, and it includes short circuit protection.
Environmentally, the P51-15QX operates within a temperature range of -25°C to +71°C, with an optional wider range available. Storage temperature is -25°C to +85°C. Cooling is achieved through free air convection.
