The following stack configurations can be driven by the PLXD:

• Two bridges connected in parallel (12 thyristors) or a six-pulse, two-quadrant bridge (6 thyristors).
• 12 thyristors in a 6-pulse, 4-quadrant regen anti-parallel bridge.
• Within the gate drive capabilities, additional stacks can be utilized simultaneously.
• Plug-in screw terminals are used for all customer control connections.

Description:

• The PLXD's three-phase auxiliary supply inputs (EL1/2/3) can handle up to 690 volts of AC.
• External stacks can be of greater voltage if necessary.
• Up to +/-1000 volts DC can be monitored using the armature voltage inputs.
• For controlling fields up to 32 amps, there is an integrated motor field bridge with independent single-phase AC supply inputs (EF2/3).
• The input voltage rating of the internal field bridge supply is 500 volts AC.
• It is possible to manage an external field using main gate pulse transformer drivers that the user supplies, as well as to provide an external field feedback signal.
• For those who would rather not provide their own components, a pulse transformer unit (Product Code LA102800) is offered at an additional cost.
• It includes every external interface part needed to integrate the PLXD with the thyristor stack and the AC current transformers that go with it.
• It consists of an armature burden rectifier network, two pulse transformer networks for an external field bridge, and twelve pulse transformer networks for two or four quadrant bridges.
• Screw terminals are used for all interface connections, and the unit is intended to be installed on a DIN rail.
