XP Power's new JHM series of ultra compact low power isolated dc/dc converters is available in 3 and 6W board mounted variants and packaged in an industry standard 24-pin DIP package. The converters conform to the international medical equipment safety standards UL / IEC 60601-1 and CSA-C22.2 No 601.1 and provide 3,000Vac input to output isolation for up to one minute, meeting the secondary isolation requirements for BF and CF applications, and 5,000Vac isolation up to 10ms for defibrillation proof compliance.
The JHM series comprises a total of 20 models. The 3 and 6W units are available in +12 Vdc or +24 Vdc nominal input versions covering the anges of +10 to +17 Vdc or +20 to +30 Vdc. Single output models are vailable with +5, +12 or +15 Vdc outputs. Dual output models offer +/-12 or +/-5 Vdc options. Output voltages are fully regulated to within +/- 0.3% over all input conditions and less than +/- 2.0% over all load conditions.
The converters are capable of operating in most environments without any additional heat sinking or forced airflow. Full load output is available from -20 degrees C to +60 degrees C and up to the maximum case temperatureof +100 degrees C with derating.
The units conform to EN55011 and EN55022 level A standards for conducted and radiated EMI without the need for any additional external components.
