The Polytron P31-M/22 is an enclosed AC/DC converter designed for ITE (Commercial) applications. It provides a regulated -15V DC output with a current capability of 25mA per output, featuring two outputs in total.
This converter operates with an input voltage range of 105-125 Vac at 50-60 Hz. 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%, with a temperature coefficient of ±0.02%/°C typical. It offers 50MOhms isolation resistance and includes Short Circuit Protection.
The unit is designed for Through Hole mounting and comes in a 5-DIP Module package. It operates within an ambient temperature range of -25°C to +71°C and has a storage temperature range of -25°C to +85°C. Cooling is achieved through free air convection.
Compliance certifications include CE, cURus, and UL. The RoHS status is listed as RoHS3 Compliant, MSL as 1 Unlimited, and REACH as Unaffected, though these compliance details are currently unverified.
