Frequently Asked Questions
What are the main output specifications of the Mean Well GST90A12-P1M?
This model provides a 12V DC output with an 80W power rating. Its rated output current is 6.67A, making it suitable for equipment that requires a regulated 12V desktop power supply in that power range.
What type of DC plug does the GST90A12-P1M use?
The GST90A12-P1M uses the P1M DC plug format. The listed plug size is 2.5mm inner diameter by 5.5mm outer diameter by 11mm length, with a tuning fork type design.
What input voltage range does this power supply accept?
This model has a universal input range of 90 to 264VAC, and it also supports 127 to 370VDC. That broad input range makes it suitable for commercial applications across different mains power environments.
Is the Mean Well GST90A12-P1M an energy-efficient power supply?
Yes. It is specified as Energy Efficiency Level VI and has no-load power consumption below 0.075W. The description also states compliance with EISA 2007 and NRCan requirements.
What protection features are included in this 12V power supply?
The GST90A12-P1M includes overload, over-voltage, and over-temperature protection. The overload protection is listed as hiccup mode with auto-recovery, which helps protect both the power supply and connected equipment during abnormal conditions.
Is this model intended for grounded Class I applications?
Yes. The product description identifies it as a Class I power supply with earth pin only, and it uses a 3-pole IEC320-C14 AC inlet. That makes it appropriate for applications that require an earth-grounded desktop adapter design.
Can this power supply be used in demanding temperature environments?
The product data lists an operating range from -30°C to 70°C. The description also highlights a wide working temperature capability and notes output derating should be considered at higher temperatures.
What kinds of applications is the GST90A12-P1M typically suited for?
This is a desktop-style AC/DC power adapter for equipment that needs 12V DC at up to 80W. Buyers typically consider this type of model for industrial, commercial, and electronic devices where stable 12V output, Class I grounding, and recognized safety approvals are important.
