MEAN WELL 180W Power Brick AC/DC-voeding 12V 0-15A GST220A12-R7B

The MEAN WELL 180W Power Brick AC/DC Adapter (model GST220A12-R7B) delivers a stable 12V DC output with up to 15A of current in a compact desktop enclosure. Designed for general power applications, this desktop power supply accepts a wide input range (85–264VAC / 120–370VDC) at 47–63Hz and uses a standard 3-pin IEC320-C14 mains connector. It is optimized for efficiency with up to 94.5% efficiency and very low no-load consumption below 0.15W.

Advantages

The GST220A12-R7B offers continuous 180W output in a fully enclosed, flame-retardant (94V-0) casing and meets Level VI energy efficiency. Built-in protections include short-circuit, overload, over-voltage and over-temperature safeguards, and an LED power indicator simplifies status checks. The adapter operates across a wide temperature range from -30°C to 70°C, making it suitable for varied environments.

Key specifications

How to use

Connect the adapter to a compatible AC mains supply using the IEC320-C14 power cord and attach the 12V DC output to the device requiring power, ensuring correct polarity and connector fit. Verify the device’s required voltage and current do not exceed the adapter’s 12V/15A rating. Observe the LED indicator to confirm power status and allow appropriate ventilation around the adapter during operation.

Recommendations

To maximize service life and safety, operate the power brick within the specified ambient temperature range, avoid covering the unit to prevent overheating, and use a properly rated mains cable and grounded outlet. If the adapter shows signs of fault (no LED, unusual noise, or excessive heat), disconnect and have it inspected or replaced.
