PSM03A Series Wall Adapters


Phihong USA expands the PSM03 series with standard DC cord and additional output voltages

Phihong USA has expanded their 2.75 W power adapter offering to include a new series of small, fixed, wall-plug adapters with standard DC cords. Based on their best-selling PSM03A USB chargers, Phihong's new PSM03A series is available in 5, 7.5, 9, 10, and 12 V outputs and features a CC/CV function, making it ideal for battery charging in applications such as medical testing equipment, personal electronics, cameras, and cordless tools.

Phihong's new PSM03A fixed wall-plug adapters are compact, low-profile, and are fully equipped with over-voltage, over-current, and short-circuit protection. The Class B EMI wall-plugs are also compliant with UL safety regulations, featuring a no-load power draw of less than 0.15 W and meet the requirements for a Level V efficiency rating.

The PSM03A adapters with DC cords measure 39.4 mm x 43 mm x 21 mm and weigh 45 g. Their DC cords are 1500 mm long and are terminated by a standard, center-positive, straight barrel connector. Additional DC tips are available and may be substituted to suit individual applications, with no minimum order quantity.
