The Polytron P31-12M is a board-mount AC/DC converter designed for commercial ITE applications. It converts a nominal 115VAC input (105-125VAC range, 50-400Hz) to dual ±12VDC outputs, each rated at 25mA. The converter offers ±1.0% voltage accuracy at full load, with line and load regulation of ±0.2% each. The typical temperature coefficient is ±0.02%/°C.
The P31-12M provides short circuit protection and operates over a temperature range of -25°C to 71°C with free air convection cooling. It is packaged in a 5-DIP through-hole module measuring 51.0mm x 51.0mm x 22.2mm. Isolation resistance is 50MOhms.
This converter carries approvals from CE, cURus, and UL, and is suitable for powering isolated dual-rail circuits in instrumentation, control, and communication equipment.
