The PL/XD makes an extremely economical solution for users of very large power DC motors wishing to separate the control and power modules.
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).
Available in 2Q (single direction) and 4Q (fully regenerative) variants, the range comprises 3 compact chassis sizes with models rated at 150% overload (standard) or 250% overload (high duty). The JL/X boasts an extremely versatile operating input voltage range of 12V – 500VAC as standard. Options are available for 600V and 690VAC input.
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.
