TRACOPOWER Switching Power Supply 48V DC 450W 264V AC Screw Mount TPP 450-148-M

TRACOPOWER TPP 450-148-M switching power supply delivers reliable 48V DC output at 450W power with a maximum input voltage of 264V AC. Designed with a reinforced double I/O isolation system, it maintains a very low earth leakage current below 100 μA, which is particularly suitable for BF (body floating) applications such as sensitive medical equipment. The unit supports operation in harsh environments with an extended temperature range from -40°C to 80°C.

With high efficiency of 94%, this power supply reduces energy consumption and heat generation, supporting both forced air cooling at full power and convection cooling up to 320W without derating up to 50°C. The compact 3" x 5" open frame design (148.2mm x 80mm x 40.6mm) fits space-critical applications, while the integrated variable fan speed controller allows flexible thermal management when an external fan is employed.

Additional features include a 5V standby output, 12V auxiliary output, Remote On/Off capability, and Power Good signal monitoring. The product conforms to rigorous medical and electronic equipment standards EN 60601-1 and EN 62368-1, ensuring safety and compliance in professional environments.

This power supply is widely used in industrial, medical, laboratory, HVAC, and manufacturing applications where reliable and efficient DC power conversion is essential. Manufactured in Taiwan with premium-grade industrial components, it demonstrates high reliability and longevity under demanding operational conditions.
