Description
The GSM120A series is a highly reliable, 120W desktop style single-output green medical adaptor. It features a 3-pin (with FG) standard IEC320-C14 power plug and accepts an input range from 80VAC to 264VAC. The series offers various output voltages from 12VDC to 48VDC, catering to diverse medical electrical devices. Its circuitry adheres to international medical standards (2*MOPP) with an ultra-low leakage current (<100μA), making it suitable for medical devices in direct electrical contact with patients. With up to 91.5% efficiency and less than 0.15W no-load power consumption, the GSM120A complies with energy standards like USA EISA 2007/DoE, Canada NRCan, Australia and New Zealand MEPS, EU ErP, and CoC Version 5. It utilizes a 94V-0 flame retardant plastic case and has obtained international medical safety certifications.
Model Encoding
The model number is structured as GSM120A [Output Voltage]-[DC Plug Type]. For example, GSM120A12-R7B indicates a 12V output with the R7B DC plug type. R7B signifies a standard model with a Power DIN 4Pin with lock type. Other DC plug options are available upon customer request.
