The 25-40 watts PKA 2000 series hybrid DC/DC power modules are 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, these highly reliable products comply to demanding applications within e.g. cellular radio, medical, industrial and airborne industri. Input to output isolation is 500 Vdc . Mechanical ruggedness in conformance with IEC 68-2 - is close to requirements for discrete
