The Astrodyne TDI PFC-650U is a 650-watt AC to DC converter module designed for demanding applications. It operates from a universal input voltage range of 90 to 265VAC and input frequencies from 47 to 440Hz, providing a stable 375VDC output.
This module boasts extremely high conversion efficiency, typically 94%, and a near-unity power factor of 0.99 typical. It features a high power density of 150W/in³ and is suitable for rugged, environmentally challenged applications due to its advanced electrical design and thermal management techniques. The PFC-650U operates within a baseplate temperature range of -40°C to +100°C.
Packaged in a compact 3/4 brick form factor (3.6 x 2.4 x 0.5 inches), it is designed for through-hole mounting. The module includes features such as Active Inrush Current Limiting and an LD ENA signal to control downstream converters. It is also MIL-STD-704/DO-160 compatible, making it ideal for military and aerospace applications, as well as ITE (Commercial) use.
Key specifications include an output power of 650W, an output voltage of 375VDC, and an output current of 1.75A. The input voltage range is 90-265VAC, with an input frequency range of 47-440Hz. The unit is RoHS3 Compliant and has an MSL of 1 Unlimited.
