Products Feature:

1 . Substantial reduction of harmonic current on power source side

SD3200 suppresses the harmonics by using a multi-pulse diode rectification system (12 to 60 pulses),thereby substantially reducing the generation of harmonics in comparison with previous models. The harmonic generation level stipulated in IEEE 519 (1992) is satisfied. This inverter is ideal for power sources.



2 . Total inverter effi ciency as high as approximate 97%

a). Because an output transformer is unnecessary, inherent losses are eliminated.

b). Multi-level PWM control minimizes switching loss.

c). Because the harmonic current on the power source side is reduced, the primary winding of the input transformer

has a reduced harmonic losses


3 . Source power factor as high as 95% or more

a). Due to full-wave rectifi cation with multi-phase diodes,operation is allowed with the source power factor (power factor on power source side) set at a high level.

b). A phase advancing capacitor and a DC reactor for improving the source power factor are unnecessary.

c). A smaller power capacity suffices for inverter operation.

4. High-reliability

a) . Higher equipment reliability is achieved by reducing the number of inverter cells by using a single-phase,3-level inverter, etc..

b). Stable operation is maintained despite load fluctuations, by the simple sensor-less vector control function.

c). The control device has a 32-bit MPU for quick response and high-accuracy.
5. Vector control

Vector control with a speed sensor is available (as an option) for equipment having high speed and torque accuracy requirements. (option)

6. Easy maintenance

a). The inverter is air-cooled, requiring no cooling water.

b). Start/stop operation, parameter setting, fault display and data monitoring are performed on the touch panel with simple loader functions.

c). Simple, built-in auto-tuning functions facilitate testing and adjustment.

d). Fault diagnoses are easily performed.

e). A dry-type input transformer is adopted.
