Estratti del catalogo

Modern aircraft are moving towards 270VDC power, yet legacy loads often require 3-phase input power. The GE Aviation Non-Linear Inverter, converts 270 VDC input power into regulated 115 VAC, 400 Hz, three-phase output and is capable of continuously providing 10,000 VA of output power to non-linear type loads. It can power loads with many different qualities; diode rectification input AC voltage, operation on single phase inputs (unbalanced loads), or highly capacitive or inductive devices. The 3-phase Inverter provides overload and short circuit protection with automatic recovery. High power density is provided using GE Silicon Carbide (SiC) modules. This enables switching frequencies of 5 to 10 times that of Silicon devices. The NLI increases power availability to the platform, thus eliminating the need to shed critical system loads to bring different systems online. Features Physical Weight: < 16 kg (35 lbs.) W - 209mm (8.26”) L - 329mm (12.97”) Environmental Coolant -400 C to +500 C, 1.5 gpm, 25 psid; 150 psig input pressure. Tailorable to system requirements.
