Description

The GSM120B is a highly reliable 120W medical desktop adaptor designed for a wide range of medical applications. Featuring a 2-pin (no FG) IEC320-C8 standard power plug, it supports an input range of 80VAC to 264VAC. The GSM120B series offers various output voltages from 12VDC to 48VDC, accommodating the power needs of different medical devices.

Built to meet international medical standards (2*MOPP), the GSM120B ensures ultra-low leakage current (<100µA), making it ideal for medical equipment that requires direct patient contact. With an efficiency rating of up to 91.5% and no-load power consumption of less than 0.15W, this medical desktop adaptor is fully compliant with energy regulations, including USA EISA 2007/DoE, Canada NRCan, Australia and New Zealand MEPS, EU ErP, and Code of Conduct (CoC) Version 5. These features ensure significant energy savings in both active and standby modes.

The GSM120B is housed in a 94V-0 flame-retardant plastic case that provides double insulation to prevent electrical shocks. It is also certified by international medical safety standards, ensuring its suitability and reliability in critical medical environments.
