Product Summary
The PKA2231PI is a 25–40 W DC/DC Power Module. The PKA2231PI is especially designed for decentralized 24/28 Vdc system distributed onboard DC/DC coverters. By using a thickfilm thecknology, which provides a high degree of intergration as well as efficient thermal management, and by utilizing a 300 kHz switching frequency, the highly reliable PKA2231PI complies to demanding applications within Input to output isolation is 500 Vdc . Mechanical ruggedness–in conformance with IEC 68-2 - is close to requirements for discrete components. Extreme temperature conditions can be met since the converters can operate with full output power in ambient temperatures ranging from –45 to +85℃ or up to +115℃ case temperature, making the PKA2231PI ideal also for applications within various non-controlled environments.
