Mean Well GST90A48-P1M Power Supply 90W 48V

This model is a 90W AC/DC desktop power supply with a 48V DC output. It is rated for 1.8A output current. The input range is universal at 90 to 264VAC, which helps support global B2B equipment deployments.

The GST90A48-P1M uses Mean Well's P1M plug style. The listed standard DC plug size is 2.5mm ID x 5.5mm OD x 11mm length, tuning fork type. Buyers should confirm their device requires this exact plug format before ordering.

It is built for professional equipment use where a regulated 48V, 90W external power supply is required. This model includes overload, over-voltage, and over-temperature protection, along with active PFC and Level VI efficiency. Those features make it a strong fit for B2B applications that need an enclosed, branded external PSU.

This model is rated to Energy Efficiency Level VI and has no-load power consumption below 0.075W. It also meets EISA 2007 requirements and is NRCan compliant. That makes it a better choice for businesses that want lower standby losses and improved energy performance.

The GST90A48-P1M is listed with multiple safety approvals including UL60950-1, CSA 22.2, TUV EN60950-1, BSMI CNS14336, PSE J60950-1, and CCC GB4943. EMC compliance includes EN55022 Class B, EN61000-3-2/3, FCC Part 15/CISPR22 Class B, CNS13438 Class B, GB9254, and GB17625.1. These approvals are useful for OEM and business buyers working across regulated markets.

The structured product data lists an operating temperature range of -30°C to 70°C. That makes it suitable for many equipment environments where a standard consumer-grade adapter may not be sufficient. Final suitability still depends on the end equipment, enclosure, and overall thermal conditions.

This power supply accepts a universal AC input and uses a 3-pole IEC320-C14 inlet. It is a Class I unit, meaning it is designed for grounded operation, and it comes in a fully enclosed plastic case with an LED power-on indicator. The compact housing is listed at 145 x 60 x 32mm.
