New 1W and 2W DC converters meet MOPP/ MOOP medical needs

PowerPax now supplies Mornsun's new G & H series medical DC converters. The range features unregulated dual-output G series and single-output H series converters in both 1W and 2W variants in industry-standard SIP black flame-retardant and heat resistant plastic (UL94 V-0 rated) package. The series is aimed at the medical market with all parts meeting the medical design standards EN60601-1 and ANSI/AAMI ES60601-1 3rd Edition (1xMOPP/2xMOOP). The converters feature fixed inputs of 3.3VDC, 5VDC, 12VDC and 24VDC with a ± 10% range and have efficiency levels of up to 81%. Dual outputs are provided in the range ±5VDC to ±15VDC with single outputs available from 3.3VDC to 15VDC. All models feature exceptional ripple and noise characteristics with line regulation of ±1.5 % maximum and load regulation of 15% typical. This series features reinforced insulation and input to output isolation of 4200V AC/6000V DC for one minute. The internal transformer is specifically designed to ensure that the creepage and clearance of the module's transformer is 5mm minimum and the creepage and clearance on the PCB is 5.5mm minimum, patient leakage is less than 2µA, (250VAC 50/60Hz). The operating temperature range of these converters is -40C to +85C and they have an MTBF of 350K hr’s (MIL-HDBK-217F). The converters are primarily designed for use in medical application but the compact size, high isolation, low isolation capacitance and low leakage characteristics make them ideal for a wide range of applications where these characteristics are desirable, says the company.
