XP Power announces the JHM10 series of board-mounted compact, isolated, 10 W DC-DC converters. Meeting the ANSI/AAMI ES60601-1:2005/IEC60601-1 3rd edition medical safety standard and having a maximum leakage current of 2 μA, the series meets the stringent international regulatory requirements for patient-connected medical equipment. The converters have a reinforced input-to-output insulation at a working voltage of 250 VAC and provide an isolation of up to 4,000 VAC for up to 1 minute, and up to 5,000 VAC for up to 10 milliseconds (defibrillator proof), and, as required by the 3rd edition, have two means of patient protection (MOPP). Isolation capacitance is 20 pF.
The series comprises of three ranges accepting wide 2:1 inputs of 4.5 to 9 VAC, 9 to 18 VAC or 18 to 36 VAC with either single- or dual-outputs. Single-outputs are 5, 12, or 15 VAC, and duals provide ±5, ±12, or ±15 VAC. The regulated outputs vary no more than ±0.3% under all input conditions and less than ±2.0% under all load conditions. Outputs can be trimmed up to ±10% of stated nominal output.
Measuring just 31.75 x 20.32 x 16.5 mm (1.25 x 0.8 x 0.65 inches), these miniature converters fit a standard DIP 24-pin-out footprint, keeping board space to a minimum and making them suitable as a drop-in replacement part for use in older designs.
The JHM10 series meets EN55011 and EN55022 level A standards for conducted and radiated EMI without the need for any extra external components. Able to operate in most environments, the series can accommodate temperature from -40°C to 80°C without any additional heat-sinking or forced airflow. The units de-rate above 50°C and the maximum case temperature is 100°C.
Suiting a wide-range of patient-connected medical applications the JHM10 series is perfect for any design that requires a high-level of voltage isolation, a low-isolation capacitance together with a low level of leakage current.
