Fonte de alimentação MEAN WELL GST90A19-P1M 90W

The MEAN WELL GST90A19-P1M is a 90W AC-DC industrial desktop adapter with power factor correction (PFC). It accepts a wide input voltage range of 90–264 VAC via a 3-pin IEC320-C14 socket and provides a single 19 V DC output at 4.74 A. The adapter is fitted with a P1M tuning fork plug (outer diameter 5.5 mm, inner diameter 2.5 mm) and comes with a fixed cable approximately 1200 ± 50 mm long. It complies with RoHS requirements and is designed for reliable, continuous use in desktop and equipment-powering applications.

Advantages

The GST90A19-P1M offers wide input voltage compatibility (90–264 VAC) and integrated PFC for improved efficiency and reduced mains distortion. Its compact enclosure (60 × 145 × 32 mm) and standardized IEC320-C14 inlet make it easy to install in desktop and rack environments. The fixed P1M output connector and consistent 19 V / 4.74 A output provide plug-and-play convenience for compatible devices. RoHS compliance ensures the unit meets environmental substance restrictions.

Suitable for

• Powering routers, switches and network appliances that accept 19 V DC
• Desktop electronics and consumer devices requiring a 19 V, 4.74 A supply
• Equipment racks or service areas where a compact 90W adapter is needed

How to use

Connect mains power to the adapter using a compatible IEC320-C13 power cord and plug the P1M tuning fork output into the device’s 19 V DC input. Ensure the adapter is placed on a flat, stable surface with adequate ventilation and that the total load does not exceed 4.74 A. Verify polarity and connector fit before powering the connected equipment.

Recommendations

Use the adapter within the specified input voltage range (90–264 VAC), avoid exposure to liquids and excessive heat, and allow sufficient airflow around the unit. For critical applications, verify device compatibility with a 19 V, 4.74 A supply and consider using surge protection or an uninterruptible power supply (UPS).
