GSM25U series - 25W series AC-DC High Reliability Medical Adaptor

• Blood glucose meter
• Blood pressure meter
• Nebulizer
• Inhaler
• Portable medical device



The GSM25U series is a highly reliable 25W wall-mounted style single-output green medical adaptor. This unit is equipped with a 2-pin (no FG) standard USA AC power plug, adopting the input range from 80VAC to 264VAC. The entire series supplies different output voltages between 5VDC and 48VDC that can satisfy the demands for various kinds of miniature medical devices. The circuitry design meets the international medical standards (2 x MOPP), having an ultra-low leakage current (<50µA), making the unit suitable for applications with direct contact with patients.
These units have an efficiency of up to 88% and an extreme low no-load power consumption below 0.1W, The GSM25U series is compliant with USA EISA 2007/DoE and Canada NRCan; the supreme feature allows the adaptor to save the energy when it is either under the operating mode or the standby mode. The entire series utilizes the 94V-0 flame retardant plastic case, providing the double insulation that effectively prevents electrical shock.

The GSM25U series is approved with the international medical safety certificates.
