The Powervamp PS300 is a solid-state portable aircraft DC ground power supply designed to deliver regulated 28V DC power up to 300A continuous output for avionics operation, maintenance, and aircraft ground servicing.

It is built using multiple internal power modules operating in parallel, providing stable high-current output suitable for powering full aircraft electrical systems, including avionics suites, lighting, and environmental systems during maintenance or pre-flight checks. The unit is commonly used in MRO hangars, FBO operations, and airline maintenance environments.

The PS300 is designed for plug-and-play aircraft connection via standard ground power receptacles, offering protection features such as current limiting, short-circuit protection, and thermal shutdown. Its solid-state design ensures low ripple output, making it safe for sensitive avionics systems.
