GST18/GST25/GST36 Low Wattage Green Adapters

MEAN WELL GST18/GST25/GST36 Low Wattage Green Adapters (Level VI) are available in two types: the desktop type (A/B type) and wall-mounted type (E/U type), with 18W, 25W, or 36W respectively. These adapters comply with EISA 2007/DoE Level VI energy efficiency regulations. The no-load power consumption and working efficiency of the GST18/25/36 adapters far exceed the performance of the Level V series adapters. The GST18/GST25/GST36 Low Wattage Green Adapters are ideal for use in various types of consumer electronic devices, telecommunication devices, office/commercial facilities, industrial equipment, and a variety of systems that must meet the latest energy regulations.
