Sprint Electric >Products>PL/XD Series

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).

COMPACT & VERSATILE DESIGN

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.

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.
