It is ruggedized and conformal coated to ensure immunity to shock, vibration and humidity, and is suitable for industrial, utility, telecom and marine environments, as well as for aviation ground support equipment, fuel cell, solar cell and wind power conversion systems. This solid state inverter incorporates microprocessor controlled high frequency PWM technology to synthesize sinusoidal outputs of 208Vrms, 380Vrms or 415Vrms (phase-to-phase) from 24V, 28V, 48V, 125V or 250VDC inputs. Total harmonic distortion at full load is less than 5%. The floating outputs are isolated from each other and can be connected in a ‘Y’ configuration or left as three individual outputs. In ‘Y’ configuration, the centre point (neutral) can be grounded.
