Pacific Power Source has introduced a range of precision programmable linear AC power sources for a wide range of AC power test applications. The LMX Series consists of over 20 different models ranging in power from 500VA to 30,000VA. Compared to legacy PWM switching AC power sources, the LMX Series uses linear technology to offer superior performance with respect to output noise, voltage distortion, output impedance and peak current capability. The LMX Series also offers a 15Hz to 5,000Hz output frequency range, which is higher than most switch-mode AC power sources. This allows the LMX to support gyro and other navigational avionics equipment applications that require AC frequencies well above 1,000Hz. Housed in a 19" rack mount chassis, the LMX Series can be used on an engineering bench as well as easily integrated in an automated test station. LAN with LXI, USB, GPIB and RS232 Remote control interfaces are all standard and with the available PPSC Manager Windows 10® software, compliance testing to a wide range of avionics and commercial power standards is available without the need to write custom programs. This includes D0160, Mil-Std 704, Airbus ABD0100.1.8, ABD0100.1.8.1, AMD24D and Boeing B787, as well as IEC 61000-4 Grid.
