The PWF series is a family of programmable AC power source with wide range of adjustable frequency, developed for aerospace or military’s 400Hz and 800Hz test applications, such as lab use, compliance test, and quality assurance.


The PWF series consists of L series and M series, which have different output frequency range. L series provides 45~500Hz and 0~300V output, and M series provides 300~800Hz and 0-150V output. Users can select communication interfaces of RS-485, RS-232, and optional GPIB. The PWF series also have programming sequence functions of STEP and GRADUAL modes, three phase independent control, phase angle control, and disturbance function. 。
