PD550 Single Inverter for Motor Control
PD550 Single Inverter
for Motor Control
High-power inverter integrated with brake chopper output.
Ideal for high power drive system applications.
John Deere Electronic Solutions has created the JDES family of
inverters, designed to provide advanced control for AC motor
applications. The JDES product line covers a wide range of power
levels (up to 300 kVA) and utilizes common motor control
software for efficient control of IPM or induction motors.
The PD550 single inverter is based on high performance DSP
real-time embedded software to support advanced features such
as field-oriented control. The high-voltage, high-power modules
are designed to work at maximum efficiency with complete
monitoring capabilities to ensure control under all conditions.
The thermal management system is liquid-cooled for robust and
reliable performance over the life of the system.
