The Polytron P37-12XA is a linear encapsulated power module designed for AC to DC conversion. This enclosed unit provides dual outputs of -12VDC, each capable of supplying 500mA. It is designed for through-hole mounting and includes short circuit protection for enhanced reliability.
The module operates within a temperature range of -25°C to +71°C and features a free-air convection cooling method. Its physical dimensions are 88.9mm in length, 63.5mm in width, and 51.0mm in height. The P37-12XA is suitable for ITE (Commercial) applications and carries CE, cURus, and UL approval agency certifications.
Key electrical specifications include a nominal input voltage of 115 VAC at 50-60 Hz, with line and load regulation of 0.2%. The voltage accuracy at full load for single outputs is 1.0%, and the temperature coefficient is a typical 0.02%/°C. Isolation resistance is rated at 50 MOhms.
The P37-12XA operates from a nominal 115 VAC input at 50-60 Hz. A 400 Hz option is available.
The standard operating temperature range is -25°C to +71°C. An optional extended range of -40°C to +85°C is available.
The P37-12XA is packaged in a 7-DIP Module with 5 leads and is designed for through-hole mounting.
The converter provides dual outputs: +12VDC and -12VDC, each rated at 500mA.
Yes, short circuit protection is included.
Line regulation is ±0.2% and load regulation is ±0.2% for single output.
It is approved under CE, cURus, and UL standards.
