The Pacific Power AFXT/ADFT Series Transformer Module delivers programmable AC and DC voltage transformation across laboratory, industrial, and OEM applications. This modular platform generates 0–400 Vac L-N (0–692 Vac L-L) and 0–440 Vdc outputs with extended DC capability to ±850 Vdc in series configuration. Operating from DC through 3000 Hz with optional frequency range extensions, the module executes complex transient profiles across 200 steps and 400 segments using sine, square, triangle, clipped sine, and arbitrary waveforms. Constant power operation maintains full output down to 160 Vac L-N (277 Vac L-L), enabling wider voltage and current ranges without range switching. Real-time impedance programming, phase angle control (0.0°–359.9°), and multi-phase transient generation support demanding test scenarios. Integrated protection includes programmable peak current limits, over-current fold-back, power and apparent power fold-back, and over-voltage/temperature safeguards. The module interfaces via USB, Ethernet (LAN) with LXI support, RS-232, and embedded web server. Preconfigured cabinet models span 18 kVA through 150 kVA across 15U and 28U rack heights. Operating efficiency reaches 85%.
