The Polytron P31-12MW is a linear encapsulated AC/DC power module designed for ITE (Commercial) applications. It provides a regulated -12VDC output with a current rating of 25mA for each of its two outputs. This converter features Through Hole mounting and includes Short Circuit Protection (SCP).
The operating temperature range for this unit is -40°C to 85°C, with cooling provided by free air convection. The physical dimensions are 51.0mm x 51.0mm x 22.2mm. The module is approved by CE, cURus, and UL.
Key electrical specifications include a nominal input voltage of 115 Vac at 50-60 Hz or 400 Hz. Line and load regulation are both ±0.2% for single outputs, with a voltage accuracy of ±1.0% at full load for singles. The temperature coefficient is typically ±0.02%/°C, and isolation resistance is 50MOhms.
