XP Power today announced the JHM series of ultra compact low power isolated DC/DC converters. Offering 3 and 6 Watt 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. The units provide 3,000VAC input to output isolation for up to 1 minute, meeting the secondary isolation requirements for BF and CF applications and 5,000VAC isolation up to 10milli-seconds for defibrillation proof compliance. Any medical appliance that may involve patient contact needs to provide isolation from hazardous voltages and have an extremely low leakage current. With such a small leakage current of 2uA, and low 20pF input to output capacitance, the JHM series meets these requirements and provides a reliable and cost effective solution for designers of medical equipment.
The JHM series comprises a total of 20 models. The 3 Watt and 6 Watt units are available in +12VDC or +24VDC nominal input versions covering the ranges of +10 to +17VDC or +20 to +30VDC. Single output models are available with +5, +12 or +15VDC outputs. Dual output models offer +/-12 or +/-15VDC 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 -20C to +60C and up to the maximum case temperature of +100C 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.
