CONVERTITORI STATICI d'ENERGIA ELETTRICA CATALOGO PRODOTTI 220Vdc INVERTER Rev.o INV220 SERIES The ELIT inverter, INV 220 series, are outcome of a long experience both in UPS and in converters field. All of our equipments distinguish themselves by the employment of advanced technological components, excellent reliability and easy maintenance. The simplicity of working is the main feature of These apparatus are studied to be employed Petrochemical and industrial plants Railway field Civil and military aviation Civil and military nautical The IGBT ELIT inverter, INV 220 series, transforms the continuous voltage into an alternating sinusoidal stabilized voltage. The PWM modulation technique used reduces the harmonic content of the output and limits voltage deviations under step load conditions. The main components that composed the IGBT conversion unit (Inverter) ■ Output insulation transformer ■ Static switch as option Manual by-pass as option Insulation transformer for emergency line Parallel kit feature as option INVERTER ELIT INV 220 COMPOSITION a) IGBT Greatz bridge type with PWM b) Output current limitation c) Output voltage detector min - max d) Heat sink temperature detector e) DC link voltage detector min - max f) Short circuit running STATIC BYPASS SWITCH fAS OPTION) The bypass static commutator transfers the load from the inverter to mains upon failure or The transfer occurs automatically without a) Min - max mains voltage monitor b) Quartz mains frequency monitor c) Mains - inverter transfer manual or automatic and vice versa d) Transfer inhibition mains - inverter after e) Heat sink temperature detector If any condition out of inverter characteristics occurs, the static bypass switches the load to the emergency line and the inverter is disconnected. When the normal conditions are restored, the inverter will be connected
