Availability: High availability architecture Different running modes : hot stand-by, integrated parallel, or centralized static switch for multi-modules leading to availability architectures Compatibility: Parallel capability Multiple units can be placed in parallel to meet power capacity and redundancy requirements Output synchronization to external source UPS can be synchronized with any other independent source to use downstream static transfer switches. Economy: Advanced electrical features Excellent power conditioning, very low harmonic distortion through IGBT rectifier, input power factor correction, and high efficiency. Output Voltage Distortion Less than 2% Output Frequency (sync to mains) 50 Hz,60 Hz Other Output Voltages 380,400,415 Crest Factor 3 : 1 Output Connections: (1) Hard Wire 3-wire (3PH) (1) Hard Wire 4-wire (3PH + G) (1) Hard Wire 4-wire (3PH + N) (1) Hard Wire 4-wire (3PH - PEN) (1) Hard Wire 5-wire (3PH + N + G) Output Voltage THD < 2% linear load and
