The FCS Series provides high output single or three phase power. Used primarily for facility wide AC power delivery or high power test applications. Three phase systems top out at 54,000 VA, single phase systems at 72,000 VA. FCS systems come in a compact, low center of gravity cabinet that can be moved around easily to different locations. Using a highly efficient pulse width modulation DC/DC converter design, the FCS series delivers more power with higher efficiency than comparable AC power systems. Both manual oscillators and programmable controllers are available for the FCS Series of AC amplifiers. Programmable controllers offer Line Disturbance Simulation (LDS) and transients for product test applications. Options for MIL-STD704D and RTCA-DO160 tests are available for avionics applications requiring high levels of output power.
