Information about the MEAN WELL GST18A28-P1J

The MEAN WELL GST18A28-P1J is a highly reliable 18W industrial desktop power supply delivering a 28V DC output at up to 0.64A rated current. As a Class I power unit (with FG ground connection) equipped with a standard 3-pole IEC320-C14 AC inlet, it supports a wide universal AC input range from 85 to 264 VAC.

Engineered for high energy efficiency up to 88.5% and featuring an ultra-low no-load power consumption below 0.075W, the GST18A series complies with international energy-saving regulations under Energy Efficiency Level VI and EU ErP. Its fanless enclosure design enables silent operation across a broad operating temperature range of -30°C to +70°C inside a 94V-0 flame-retardant plastic housing.

For safe system operation, the GST18A28-P1J features comprehensive protective circuits against short circuit, overload (auto-recovering hiccup mode), and overvoltage conditions. The "P1J" model suffix designates a standard 2.1mm x 5.5mm DC barrel plug (11mm length), making this adapter ideal for consumer electronics, telecommunication devices, office facilities, and industrial equipment.
