Hangyu Power Supply: GJB181B-2012 Aircraft Power Supply Characteristics Standard DC 28V Partial Test
The standard for aircraft power supply characteristics is not only an important standard for the design of aircraft electrical systems, but also an interface standard between aircraft power supply systems and electrical equipment; It is a standard that should be implemented during the development, production, procurement, acceptance, use, maintenance, and repair process; It is the basis for domestic and international technical coordination and inspection and acceptance of imported equipment. The evolution of GJB181 is: GJB181-1986 → GJB181A-2003 → GJB181B-2012.
GJB181 has seven major power supply testing projects, among which Hangyu Power brings a dedicated testing power supply: HY-GJB series testing power supply for DC 28V power supply testing projects. This power supply is equipped with dedicated upper computer software, specifically designed for testing the steady-state and transient characteristics of the DC 28V system in GJB181B-2012. It can simulate the electrical environment of the aircraft power supply system in normal, conversion, abnormal, emergency, electrical startup, and power supply failure situations.
The HY·GJB series is a DC regulated power supply suitable for standard testing of 28V aircraft power supply characteristics in GJB 181B-2012. This power supply can generate any waveform and set timing control, using a "linear amplifier method" to achieve the functional advantages of low ripple, low noise, and high-speed response.
