PL/XD Series

Thyristor stack controller

A digital stack controller built from the classic PL/X platform.

The PL/XD is used for controlling external 3-phase thyristor stacks for DC motors and slip-ring motors. It possesses the same functionality as the PL/X range, except that the output power stage is not included.

The PL/XD makes an extremely economical solution for users of very large power DC motors wishing to separate the control and power modules.

Based on the PL/X Drive System

The PL/XD provides the same functionality as the integrated PL/X drive, except without the power stage. 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).

State-of-the-art Digital control

The PL/XD provides gate drive pulse for driving user supplied pulse transformers with primary pulse current up to 1.5A. The PL/XD can be supplied with supply voltages up to 690VAC as standard. There is also an integral motor field bridge with independent single-phase AC supply inputs for controlling fields up to 32A or 50A. Internal field supply input voltage is set at 480VAC.

Powerful Ethernet

The PL/XD can be fully equipped with Drive.Web to enable the Industrial Internet Of Things (IIOT). Drive.Web distributed control technology uses Ethernet and powerful graphical tools to provide robust Programmable Peer Control (PPC) for drives and systems. Options for field bus systems include Ethernet, Profibus, CANbus, Modbus, DeviceNet and many more. The PL/XD is CE approved.
