ABB S-073N 3BHB009884R5211 is a high voltage inverter phase module rack. It is mainly used in the power and industrial sectors and is designed to control the speed and operation of motors for energy saving and productivity improvements.
The S-073N 3BHB009884R5211 HV Inverter Phase Module is part of the ACS2000 series of HV inverters. It is used in conjunction with other modules, such as the S-076N 3BHB009884R0021 IGCT frame, to create complete high voltage inverter systems.
The mechanical structure of the phase module consists of the closed box and its internal structure. The enclosed box includes the frame, snap-in backplane, and front panel.
The internal structure includes an IEGT unit, a diode unit, an upper manifold, a lower manifold, and an insulating spacer.The IEGT unit and the diode unit are set on an insulating plate,
creating a double layer structure in the space. A shunt is provided below the upper and lower manifolds, and the frame on the shunt is provided with a water-cooled quick-connect.
The output bus, driver unit and grip handle are set on the front panel.
The buffer-absorption circuit consists of two series inductors, resistors, diodes and capacitors. The positive terminal of the diode is connected to the inductor L2 and the
negative terminal is connected to the resistor R. The negative terminal of the diode is also connected to the capacitor C. The diode is connected to the capacitor C at the
negative end. The other end of the capacitor C is connected to the negative terminal of the capacitor C. The capacitor C is connected to the negative terminal of the Bus.
In terms of practical applications, the S-073N 3BHB009884R5211 High Voltage Inverter Phase Module is used in various industries such as power and industry.
It is used to control the speed and operation of motors to achieve energy saving and improve productivity .
