A compact controller, the PL/XD is used for controlling external 3-phase thyristor stacks for both DC motors and slip-ring motors.
The PL/XD makes an extremely economical solution for users of very large power DC motors wishing to separate the control and power modules. It possesses the same functionality as the PL/X range, except that the output power stage is not included.
The PLXD can be used with up to 690v AC on its 3 phase auxiliary supply inputs (EL1/2/3). The external stacks can be of higher voltages if required. The armature voltage inputs can monitor up to +/-1000 Volts DC.
The PL/XD uses the same frame size as the PL/X 5 – 50 model and hence is extremely compact. The PL/XD provides all the world-class control features of the PL/X series. The PL/XD can control a 6 pulse 2Q bridge (6 thyristors), 2 bridges in parallel (12 thyristors) or a 6 pulse 4Q regenerative anti-parallel bridge (12 thyristors).
Options for field bus systems include Ethernet, Profibus, CANbus, Modbus, DeviceNet and many more. The PL/XD is CE approved.
